After further granulation by drum granulator, the compound fertilizer contains nutrients required by a variety of plants, which is better than a single chemical fertilizer. So how to choose compound fertilizer?
1. Look at the packaging. Qualified products are packed in double layers to prevent moisture. There are three license numbers on the packaging surface: production license number, business license number, product quality registration certificate number, nitrogen, phosphorus and potassium content identification, and manufacturer and address. Open the outer package and there should be instructions in the bag.
2. Look at the physical properties of compound fertilizer. Compound fertilizer with good quality, uniform particle size, no caking and no pulverization.
3. Buy compound fertilizer produced by regular manufacturers. The fertilizer production line and production technology of regular manufacturers are relatively advanced, the product quality is reliable and the reputation is guaranteed.
4. Select the compound fertilizer suitable for the local area. The locally produced compound fertilizer is mostly produced according to the soil nutrient content, crop fertilizer demand law and fertilization effect in this area and surrounding areas, which is highly targeted.
5. Avoid using “dichloro” compound fertilizer for many years. “Dichloro” compound fertilizer is a compound fertilizer produced with ammonium chloride and potassium chloride as raw materials. If the “dichloro” compound fertilizer is applied year after year, the amount of chloride ions stored in the soil is large, and excessive absorption by crops will cause “chlorine damage” and soil will also cause “salt damage”.
Whether planting flowers or vegetables, we should follow the fertilization principle of “giving priority to organic fertilizer and supplemented by chemical fertilizer”. The long-term single large-scale use of chemical fertilizer is easy to cause soil hardening, soil fertility decline and soil acidification.
On the contrary, it will limit crop yield and affect product quality. Therefore, after purchasing NPK compound fertilizer granulator, we must pay attention to the treatment of various nutrient compound fertilizers.
In the process of organic fertilizer production, how to granulate the fermented raw materials is the key factor to determine whether the commercial fertilizer can enter the market. The following granulation methods are generally used.
Fertilizer production line
(1) Agglomerate granulation. Under the action of rotation, vibration and stirring, the wet powder in motion is agglomerated. Or the fluidized bed is used to coagulate dry powder and particles into suitable particles by supplying spray solution (adhesive).
(2) Extrusion granulation. It is a method of making dry powder or wet powder containing adhesive into cylindrical, spherical or sheet by mechanical processing such as extrusion, roll extrusion or pressing.
(3) Crushing and granulation. It is to crush block materials into particles of appropriate size.
(4) Melt granulation. It is a method of granulation by cooling and hardening molten liquid.
(5) spray granulation. It is a method of directly granulating solid after concentration in liquid.
(6) Liquid phase crystallization granulation. It is a method that materials crystallize in liquid phase and agglomerate into spherical particles through liquid bridging agent and stirring.
This technology is widely used in pharmaceutical industry. Because the particle shape is spherical, it is also called spherical crystallization granulation method, which is abbreviated as spherulite granulation method.
Spherulite particles are pure material particles with good fluidity, filling and compression formability. In recent years, the technology has been successfully developed. That is, polymer copolymer precipitation is added in the spherulite crystallization process to prepare sustained-release, rapid release, enteric coated, gastric coated pellets, floating hollow pellets, biodegradable microcapsules, etc. Preparation of sustained release pellets.
New dry and wet material crusher: vertical crusher and horizontal crusher. The internal chain hammer type screen free structure is adopted. Even if the materials are removed from the water, they will not be broken and stuck
Automatic multi tank batching machine – designed according to the customer’s raw material type: 2 silo, 3 silo, 4 silo, 5 silo, etc.
Mixer: including vertical mixer, horizontal mixer and double shaft mixer. The mixing structure is divided into mixing blade type, screw type, etc. the appropriate mixing structure is designed according to the characteristics of materials.
The outlet is designed for cylinder control and baffle control. Organic fertilizer granulator: including disc granulator, new wet granulator, shot blasting machine, drum granulator, etc. select the appropriate granulator according to the characteristics of raw materials.
Rotary dryer: also known as drum dryer and bio organic fertilizer dryer. Because the temperature of organic fertilizer cannot exceed 80 °, our dryer adopts hot air drying.
Cooler: similar to dryer in appearance, but different in material and performance. The dryer host is made of steam boiler steel, and the cooler host is made of carbon steel plate.
Screening machines are drum type and vibrating type. The screening machine is divided into three-stage screen, two-stage screen, etc.
Automatic metering packaging machine: including screw type and DC type, single head and double head, made of stainless steel and carbon steel, which can be customized according to customer needs.
Conveying equipment: including belt conveyor, screw conveyor, bucket elevator, etc.
In addition to the disc granulator, the fertilizer granulator is mainly suitable for the production of large-scale compound fertilizer. The investment of relevant equipment is large, the construction time is long, the energy consumption is high, the production cost is high, and there are certain environmental pollution problems.
The extrusion granulation plant for producing multi-element potassium magnesium sulfate fertilizer has the advantages of small floor area, short process flow, convenient equipment operation, less construction investment and short construction period. Therefore, the compound fertilizer production line technology project is a short, flat and fast construction project, which has a certain popularization and application value in small compound fertilizer equipment production enterprises.
Extrusion granulation of compound fertilizer production line is to extrude materials by external force. The granulation process does not need steam, which can save boiler construction investment and coal production cost. The compound fertilizer production line does not introduce water and has no drying process in the whole production process, which eliminates the large and expensive dryer in the traditional compound fertilizer production line equipment, and can be dried with fuel and drying equipment.
Therefore, the process of this compound fertilizer production line meets the needs of today’s energy-saving society.
3. In the traditional nitrogen, phosphorus and potassium fertilizer production line, hot blast stove and preheated air are used to dry the materials in the production process. Burning coal in hot blast stove will produce a certain amount of sulfur dioxide gas and pollute the atmosphere.
4. The fertilizer is less affected by the external environment (such as temperature and humidity) in the production process, with great operation flexibility and flexible process formula.
5. The compound fertilizer production line has high pelletizing rate, low moisture content, high particle strength, less system return and less caking in the production process, which has good economic benefits.
How to improve the product output and output, the key lies in the organic fertilizer granulator.
1、 According to the moisture, fineness and cohesiveness of raw materials.
Powder raw materials form spherical particles through the attachment of water. Therefore, controlling water and making water uniform have become the key factors to improve yield. The lower the moisture content, the lower the granulation rate, the higher the moisture content, the more large particles, the uneven moisture, the smaller the particle size, and the lower the yield.
2. Material fineness
It is needless to say that the material fiber has natural coarse granulation effect, rough and brittle appearance and poor formability. The higher the fineness, the better the formability and the smoother the particles.
3. Is the material sticky
In particular, organic fertilizer granulation, general raw animal manure (chicken manure, pig manure, cow manure, sheep manure, pigeon manure, etc.), straw (corn straw, straw, leaves, etc.), fungus residue, sugar residue, drug residue, monosodium glutamate residue, etc. The viscosity of general materials is poor, so some viscous fillers such as bentonite need to be added.
2、 Fertilizer granulator is selected for organic fertilizer production line.
If columnar is produced, ring mold granulator and columnar extruder are selected.
For irregular and flat ball type, select the appropriate drum extrusion granulator (depending on the die).
All kinds of granulation equipment have their own advantages and disadvantages. Different equipment shall be selected according to raw materials, investment cost (drying or not) and the needs of farmers.
Process design description of NPK fertilizer production line: 1. Batch processing:
Electronic batching or disc batching. 2. Crushing process:
The mixed fertilizer proportioned according to the design requirements is sent to the raw material crusher for raw material crushing. The purpose is to crush various raw materials to a certain fineness. Basically, the particle size of raw materials is less than 1mm, which is conducive to the material in the granulator. Roll inside to meet the standard ball.
3. Granulation process:
The crushed mixture is conveyed to the fertilizer granulator through the conveyor. The liquid phase provided by the slurry or water in the extrusion granulator makes use of the centrifugal force brought by the rotation of the fertilizer granulator to turn the material into organic fertilizer. At present, it is better to use the disc granulator to produce organic fertilizer. The granulation rate of disc granulator can reach more than 90%, but the table output is low. 4. Drying process:
The granular materials are transported to the rotary three drum dryer through the conveyor. The hot blast stove is set at the inlet of the dryer to provide heat for the drying of materials in the dryer and evaporate the water in the formed materials into water. The steam is introduced into the dust collection chamber through the fan to remove dust. After the material enters the dryer, the liquid phase of the material is high and the ball strength is low. In order to ensure the sphericity of the material, we used it in the design of the dryer. 5. Cooling process:
The moisture content of materials after drying generally can not meet the water content requirements of organic fertilizer. Cooling in the cooler is very important for the NPK fertilizer manufacturing process. 6. Screening process:
The cooled organic fertilizer still has a certain temperature. After the organic fertilizer material enters the screening machine, the organic fertilizer material is roughly classified, and the screened fine powder is directly returned to the granulator for granulation. After screening, the screened coarse material is crushed by the return chain crusher, and then returned to the granulator for re granulation. The finished product is directly sent to the silo of the packaging scale. On the other hand, compound fertilizer materials are also used for screening projects. Cooling engineering plays a certain role in reducing temperature and preventing material caking. 7. Packaging process:
The coated finished organic fertilizer enters the silo of the packaging scale, automatically counts according to the set quantity, then puts it into the packaging bag, and then through the automatic sewing system, the sewn compound fertilizer can be stacked in the silo. Warehouse. In principle, the height of each stack shall not exceed 8 bags and the height shall not exceed 10 bags. The ground must be damp proof.
From a technical point of view, the important factor in the formulation design of extrusion granulation products in NPK fertilizer production line is the characteristics of materials. Next, we discuss another aspect of the influencing factors, that is, the influence of the type of raw materials on the formula.
1. Material compatibility
Theoretically, any proportion of NP or K base fertilizer can be prepared, and trace elements and even pesticides should be added if necessary. However, materials must be limited by compatibility. The substances in the formula shall not have chemical reaction in the process of fertilizer manufacturing, and occasional reaction shall not be allowed.
2. Effect of urea on formula
The international fertilizer center has done a lot of experiments on the effect of urea on the performance of compound fertilizer, although the report does not mention the same example as the product formula we are studying, and most experiments do not carry out granulation on extrusion. Yes, but its conclusion is still useful to us.
Because urea absorbs moisture easily, the critical relative humidity of NPK compound fertilizer decreases significantly. At the same time, the international fertilizer center also found that this effect is more serious when potassium chloride is used as the potassium source of compound fertilizer.
The production capacity of the dryer must be determined by many factors. Some urea based NPK fertilizers begin to soften at 70 ℃. If the outlet temperature of the dryer is higher than this temperature, the fertilizer particles will be too soft, the granulation process will be out of control (the particles are too large), and the internal scabs will form. Drying causes difficulties in screening and transportation.
In the same report, the international fertilizer center also tested other aspects of urea, such as water absorption, moisture permeability, water holding capacity, particle integrity, fluidity and agglomeration. The result is negative, which will have an adverse effect.
In short, the formula design test and production of extrusion granulation products in compound fertilizer production line show that the use of urea in compound fertilizer will encounter great trouble, not only because it affects the storage and transportation performance of products, but also because it also has a certain impact on the production process.
The production process of organic fertilizer is mainly to granulate and dry the organic waste with water content of about 30% decomposed by fermentation, prepare round organic fertilizer by granulation and drying, add functional bacteria to produce biological organic fertilizer, and add nitrogen, phosphorus and potassium (total nutrient content is less than 15%) to produce organic and inorganic fertilizer.
After screening the fermented organic waste, the binder raw materials and other components to be compatible are measured and proportioned in proportion, and quickly mixed by the bucket elevator into the fertilizer mixer for rapid mixing.
The material slides out of the mixing bin and is evenly and continuously fed into the flat die extrusion fertilizer granulator by the disc feeder to form columnar particles; Cylindrical particles (equal in diameter and length) are polished by a circular particle polishing machine. The spherical particles are sent to the drying, cooling and screening machine by belt conveyor.
The particles are dried at low temperature and large air volume in front of the drying cooling screening machine, and then enter the cooling section for air blowing. The cold and completely cooled materials enter the screen installed at the end of the cylinder, screen out the powder and large particles, and return to the mixed granulation system; The finished product particles are transported to the finished product silo by the elevator, measured, packaged and warehoused.
(1) The new technology of flat die extrusion granulation and rounding and finishing can produce “spherical” pure organic fertilizer, organic-inorganic fertilizer and biological organic fertilizer. The process is short, the operation cost is low, the organic fertilizer particles are uniform and round, the surface is smooth, the compressive strength is high, the fluidity is good, the microbial survival rate is > 90%, the granulation rate is 85-95%, and the particle size is 3.5-4mm.
(2) The new process of flat die extrusion granulation and rounding finishing has strong adaptability to raw materials and can solve the key technical problems that are difficult to be solved by traditional granulation processes such as disc or drum:
1. The fermented organic matter can be directly used for granulation without pre drying and crushing.
2. The amount of organic materials can be increased to more than 95%.
Steps and equipment required for making organic fertilizer:

9. Enter the dryer and cooler for drying and cooling.
Maintenance method of organic fertilizer granulator:
1. Start preheating and replace grease.
2. Replace the gear oil.
3. Reasonable maintenance, full and reasonable maintenance is very necessary.
4. Replacement of vulnerable parts. Vulnerable parts are the main working parts of the new organic fertilizer granulator.
5. Humanized production. The humanized culture and humanized operation of the equipment is a warm measure to ensure the normal operation of the machine.
Introduce the steps and equipment required for making organic fertilizer and the maintenance knowledge of the equipment. Hope to help you.
The configuration of organic fertilizer production line shall be selected according to the processed raw materials. A good organic fertilizer production line will affect the overall operation and later production benefits.
Organic fertilizer manufacturing process includes fermentation compost dumper, semi wet material crusher, horizontal mixer, fertilizer granulator, organic fertilizer dryer, cooler, drum screening machine, quantitative packaging scale, etc. Organic fertilizer granulator is an important link in the manufacturing process of organic fertilizer.

The quality of the granulator directly affects the organic fermentation granules, and most consumers are visual users. The plump, compact and smooth granules will be loved by customers.
Organic fertilizer granulator has different models and prices, but it is also more suitable for users with different production needs. Now the national policy is also promoting the development of organic fertilizer operators, and there are also equipment purchases.
Subsidized services and organic fertilizer production can help solve the problem of livestock manure pollution recovery, which is also a key project promoted by the government.
We produce different types of organic fertilizer granulator, new organic fertilizer granulator, disc granulator, flat mold granulator and ring mold granulator.
The particles of the first two granulators are round. The particles of the latter two granulators are cylindrical, which can be selected by customers according to their actual needs. The right is the best.
Nowadays, like other organic fertilizer production equipment, organic fertilizer granulator is a matter of concern to farmers, because it is not only related to the rational utilization of resources, but also related to the environmental pollution of agricultural waste and livestock manure. The best way to solve these pollution sources is to return organic fertilizer to the field through processing equipment, which can not only raise land but also make money.
1. The strain and fermentation raw materials are mixed for fermentation, and the pile is turned over by a dumper during fermentation.
2. The mature raw materials are crushed and screened after decomposition, and then enter the granulation workshop through the elevator.
3. After the organic fertilizer is mixed by the raw material premixer, it enters the fertilizer granulator for granulation.
7. The dust generated during drying and cooling is divided by the air entering the dust removal device.
8. The cooled particles are then transported to the screening machine by the conveyor.
9. The dispersed organic fertilizer particles enter the quantitative packaging equipment for packaging through the conveyor belt to become finished organic fertilizer.
There are many kinds of organic fertilizer production equipment in the above organic fertilizer production process, such as fertilizer granulator, including disc granulator, flat mold granulator, new organic fertilizer granulator, etc.
Bbfertilizer is a special fertilizer made by simple BB fertilizer production equipment sx, which adjusts the proportion of mixed base fertilizer according to local soil conditions and crop nutrient demand. BBF formula is a kind of fertilizer which is more convenient and easy to be popularized.
The utilization rate of BBF is high, which has a significant effect on crop yield. Taking a common peanut as an example, the peanut with bbfertilizer had rapid emergence, early flowering period, stable growth in the whole growth period, no early senescence in the later stage and less diseases. The special BB fertilizer for peanut can improve the appearance of peanut, increase the number of effective branches, increase the number of saturated fruits, reduce the number of dried fruits and increase the yield of peanut.

Organic fertilizer is a kind of organic fertilizer made from poultry manure, combined with fermentation bacteria, straw and other auxiliary materials, using traditional fermentation methods or organic fertilizer production equipment.
For commercial organic fertilizers on the market, two more popular forms of finished organic fertilizers are powdered and granular. What is the processing technology of powdery organic fertilizer and granular organic fertilizer? Which is better?
In the process of making a series of special fertilizers, inorganic nutrients and minerals should be added according to different soil conditions and different crops. These minerals are concentrated in organic matter and trace elements, so that the fertilizer contains various nutrients needed for plant growth, such as nitrogen, Phosphorus, potassium, sodium, manganese, zinc, copper, etc.
According to the formula, nitrogen, phosphorus, potassium and fermentation material are mixed by computer and transferred to granulator for granulation. We mix organic and inorganic materials according to different series of products, and mix them well in blender. Assume that the proportion of organic materials is 12%, about 12 tons.
The production process should not be exposed to high temperature and other characteristics due to the poor formation conditions of bio fertilizer mainly composed of organic matter and cellulose and the viable bacterial population with the function of making fertilizer.
Disc granulation and drum granulation are not suitable for building materials, because these two technologies require fine grinding of raw materials, high moisture content of granulation, and generally the moisture content is about 30%, so the load is relatively large. There are different types of fertilizer granulators for your fertilizer granulation process.
For drying, the loss of effective bacteria is great, and the pelleting rate is low (about 60% – 70%), the dust is heavy, and the operating environment in the production process is poor.
Therefore, through the extrusion environment, the requirements of raw material crushing are low, the molding rate is high (more than 95%), the water content of formed particles is low, the drying load is low, the environment is dry, and the production of organic biological functions should be better. Can reduce the loss of effective bacteria, less dust and good working environment.
70 tons of organic fertilizer raw materials, using organic fertilizer special granulator. After granulation, the material is sent to the dryer by belt conveyor for drying. The particle size is 3.0-4.0 mm, and the granulation rate is more than 70%.
The recommended pelletizer is a new type of pelletizer for organic fertilizer.
(4) Drying (fertilizer dryer)
In the production process of biological fertilizer, not only does the moisture content of granules generally exceed the index after molding and need low-temperature drying, but also the moisture content of organic matter after fermentation is about 30% – 40%, and the granule after granulation is generally between 15% – 20%, which needs drying treatment, because the moisture content of fertilizer quality index is less than 14%.
The drying stage is an essential and important process in the production of biological fertilizer, which directly affects the yield, quality and energy consumption. It is very important to choose the type and specification of dryer and control the process conditions.
In order to avoid the death of effective living bacteria due to the high temperature in the drying process, the drying temperature of materials should not be higher than 60 ℃ (usually about 50 ℃). Therefore, the temperature of hot air in contact with materials should be different.
For the moisture content of different materials, generally not more than 130 ℃, it is better to control the hot air temperature by stages, which can not only improve the thermal efficiency, but also effectively avoid the death of living bacteria.
According to these characteristics, the belt dryer is suitable, because it is suitable for low temperature and low humidity drying, and it can control the temperature of hot air in sections to ensure that the material temperature is not higher than the drying temperature, and maintain the highest temperature in the whole process.
The tail of the dryer can also add natural air cooling part, and cool the material immediately after drying, It can be used many times.
It is very suitable for granular biological fertilizer, with drying permeability, stable and uniform drying of materials, no damage to particles, adjustable residence time and feeding speed to achieve the best drying effect, because most of the thermal circulating air has high thermal efficiency, and the heat source can be used.
There is a secondary granulation area in front of the steam dryer provided by the biogas boiler, The material can be granulated there. Then, the material is lifted up through the plate to be completely dried. The exhaust machine exhausts the humid hot air through the pipe at the end of the dryer, and the air enters the precipitation chamber for precipitation.
After precipitation, the tail gas is removed by the washing tower, and the ejected water is pumped out for recycling. After secondary dust removal, the waste gas is discharged into the atmosphere through the chimney.
(5) Cooling (drum cooler)
The dry material is cooled by belt conveyor and sent to cooler. The cooling process mainly includes using fan to send natural air to cooler through pipe to cool the material.
The wind direction in the cooler is counter current. The waste gas pumped into the settling chamber by fans and pipes is treated and discharged into the atmosphere as dry waste gas
After cooling, the material is screened, the crushed large particle material and the screened powder are transported to the granulator through the return belt for granulation, and the final product is packaged in the automatic packaging system.
Crops are good organic fertilizers. But we often find that when using crops, fertilizer sometimes leads to a large number of soil diseases and insect pests, And it increases year by year. I have been doing tests for several years and achieved good results. Now I have become a common element in fertilizer treatment to be faithful to agriculture.
1. Flatten poultry feces, dry in the sun, mash fine powder, and mix 1 kg of thiophene per cubic meter. After the round table is piled up, mix evenly and smear with flat mud for 15-20 days.
2. Mix fresh cow dung and sheep ash with 30% ash, then spread to 10 cm thick and spray 1 kg liquid per square meter. Liquid preparation: water 1605, carbendazim ratio 100:0.2:0.3.
3. When exposed to the sun, half human manure should be piled into a truncated cone of 50cm in the shape of a high platform, with flat mud paste, and several drugs on the top of the cork should be used to penetrate the hole, with the depth of 40cm, and then filled with liquid.
Liquid preparation: the ratio of water to trichlorfon was 100:0.5.

It is an ideal product for the majority of users. The project has also won the approval of the soil durable fertilizer Station of Henan Provincial Department of agriculture, which is a national environmental protection technology promotion project.
The advantages of organic fertilizer processed by organic fertilizer manufacturing equipment are as follows:
(1) Organic fertilizer is a kind of agricultural fertilizer processed by the equipment system of organic fertilizer production line. Organic fertilizer not only contains a large number of nutrients and trace elements necessary for plants, but also contains rich organic nutrients such as humic acid, Vitamins, auxin, antibiotics and small molecule compounds of organic nitrogen and phosphorus.
Therefore, organic fertilizer is the most comprehensive fertilizer. In addition, the amount of organic fertilizer allowed varies widely and usually does not harm crop growth. The use of organic fertilizer not only increases the crop yield in the current season, but also remains effective after several years, and the effect of fertilizer is slow and lasting.
(2) Organic fertilizer can improve soil physical and chemical properties and soil fertility. Organic fertilizer contains a lot of organic matter, generally about 200g / kg. Organic matter is an important material basis of soil fertility. Humus is the main part of soil organic matter, accounting for 50% – 65% of the total soil organic matter.
Humus is a complex organic colloid, which can adjust and buffer soil pH. Increasing the amount of soil cation substitution can improve the soil fertility retention; Increasing the content of soil organic matter is conducive to the formation of good soil structure, especially water stable aggregates. Increasing soil structure can improve soil compactness, aeration, water holding rate and thermal conditions, which have a good effect on water and determine soil fertility by fertilizer, gas and thermal conditions.
It is beneficial to improve the physical and chemical properties of soil and improve soil fertility.
(3) Organic fertilizer promoted soil microbial activity. Soil microorganism plays an important role in the transformation of organic matter, and is one of the important indicators to measure the level of soil fertility.
For example, the mineralization process of organic matter in soil, the effective process of organic nitrogen and phosphorus in soil and the biological nitrogen fixation process of beans are all related to the role of soil microorganisms.
Therefore, on the one hand, the application of organic fertilizer increased the number and quantity of beneficial microorganisms in soil, on the other hand, it provided good environmental conditions for soil microbial activity, and significantly enhanced soil microbial activity.
Secondly, it is necessary to use semi wet material crusher equipment of organic fertilizer to crush livestock manure and raw materials. Raw material matching is one of the important processes of organic fertilizer production line.
The complete organic fertilizer production line includes three processes
2. It is especially suitable for high viscosity materials. The material of fertilizer granulator should meet the production requirements of pressure, temperature and catalyst resistance, and keep the product clean. Due to the different materials of fertilizer granulator, the production process and structure of fertilizer granulator will be different, so it can be divided into steel, lining equipment, etc.
The complete organic fertilizer production line includes three processes
3. High temperature energy can be obtained after the raw materials are dried, and the next step is to cool them at low temperature. Since water cannot be used for cooling, it is necessary to separate the contact between material and water through cooler. The screening machine will screen unqualified organic fertilizer particles. The screening equipment has the advantages of high efficiency and easy operation. More details, go to https://organicfertilizerplants.com/organic-fertilizer-production-process/
A lot of garbage produced by residents every day can be used, and can be processed into organic fertilizer raw materials after secondary treatment. The market position and broad development prospect of organic fertilizer production equipment can be predicted. Automatic organic fertilizer production line is the most skilled equipment in the industry.
It can work independently without help, and has high precision, avoids the waste of resources, improves the qualified rate of products, and improves the qualified rate of products. Save a lot of unnecessary economic expenditure. It can not only save costs for the company, but also create greater economic benefits for the company, with higher output, so that the goods can enter the market at the fastest speed and the best time, and obtain a higher market share. sales volume.
Today, the development of organic fertilizer production equipment has expanded to high-speed, complete set, highly automated and diversified fields. The diversified development of organic fertilizer production equipment is inseparable from the efforts and struggle of enterprises, because in the face of such a development environment, if we want to further the development of enterprises, we must let the domestic market organic fertilizer production equipment is moving towards the road of automation.
The equipment needed for the production of biological fertilizer will make a difference in the limited market. Some technologically backward, smaller manufacturers will be driven out of the market and forced to shut down. Therefore, if you want to have a larger application group forever, you must do a good job in communication with customers, do a good job in market research, and finally make the organic fertilizer production equipment better meet the demand and serve the public.
So is organic fertilizer. In the past, farmers used accumulated organic fertilizer directly. Nowadays, with the improvement of living standards, high-tech equipment is also used for large-scale production of organic fertilizer. Is to make life more convenient production of production equipment.
Organic fertilizer production line uses organic fertilizer fermentation technology to process animal manure into harmless fertilizer, involving two kinds of probiotics, one is mature bacteria, the other is functional bacteria, which play different roles.

igh efficiency! It has the following functions:
1. Treatment of harmful bacteria in animal feces.
Through continuous high temperature and microbial balance, harmful bacteria, insects, eggs, grass seeds and other crop pests in feces can be quickly and completely killed, and the reproduction of pathogens is inhibited.
2. Deodorize and improve environmental quality
Deodorization is one of the main characteristics of organic fertilizer fermentation. Rotting bacteria can decompose organic matter, organic sulfide, organic nitrogen and so on, which can inhibit the growth of rotting microorganisms and greatly improve the environment of the site.
3. Rich nutrients
In the process of treatment, nutrients change from ineffective and slow effective state to effective and fast action state. To form natural materials with excellent water absorption and retention characteristics, prevent the loss of fertilizer and water, and become a good natural protective film of soil, so as to achieve the role of nutrient enrichment.
In the process of organic fertilizer production, powder materials are transported to disc granulator by belt conveyor. The inclination angle is 50 ° The turntable rotates with the material. Like rotary drum granulators, disc granulators use wet granulation to shape particles.
When the material reaches a certain height, its gravity and inertia separate from the disc, slide along the bending path, and complete the rolling required by granulation under the action of force.
At the same time, the liquid sprayed by the spraying system is evenly sprayed on the rolled material to condense into particles, so as to complete the whole granulation process.
Granular organic fertilizer is a complex production process in organic fertilizer. Therefore, the required organic fertilizer production process equipment is more complete. In order to make the production rhythm more smooth and ensure the quality of organic fertilizer, the quality and application effect of the production equipment of organic fertilizer are relatively strict. Therefore, it is recommended that users choose equipment from large factories to ensure the quality of organic fertilizer. The following is the introduction of the whole set of organic fertilizer production process equipment.
1. fermenting compost equipment: fermentation compost flipper is an essential equipment in the process of organic fertilizer fermentation, and fermentation is also the most important process in organic fertilizer production, which directly determines the success of organic fertilizer production. The main function of the tipper is to speed up the fermentation speed of raw materials, so that the raw materials can be fermented more evenly. The other is to control the fermentation temperature during fermentation.
2. semi wet material crusher: semi wet material crusher can break the fermented raw materials into powder. It is the necessary equipment for the production of powdery organic fertilizer, and also the necessary pretreatment equipment for the production of granular organic fertilizer.
What kind of equipment is needed to produce granular organic fertilizer?
4. organic fertilizer granulating machine: This is the most important equipment in the production line of granular organic fertilizer. There are many types of granulator, which is designed for different types of raw materials. In order to improve the success rate of granulation or meet the special needs of users.
5. Organic fertilizer dryer: the dryer is mainly used to dry the excess water in the granular organic fertilizer particles. The dried particles have high strength and are not easy to deform and degrade during transportation and storage.
6. organic fertilizer Cooler: because of the high temperature of dry particles, rotating cooler must be used to cool particles quickly, eliminate the hot gas of particles, and accelerate the cooling and forming of particles.
7. drum screen: the main function of the screen separator is to classify the particle size, and the qualified particles will enter the next process, and a small part of the particles that are too large or too small will be returned. The corresponding process is treated twice, thus forming a complete process production.
8. automatic packaging machine: even if qualified particles are transported to the finished product workshop, they shall be quantitatively packed by the packaging machine to improve the production efficiency.
The above is a complete set of equipment for the production process of granular organic fertilizer. Please pay attention to learn more about organic fertilizer equipment!
Organic fertilizer production line is made of fresh chicken manure and pig manure, and it does not contain any chemical components. However, chicken and pig have poor digestion ability, which can only consume 25% of nutrition, while 75% of the other nutrients in feed are discharged with feces.
Therefore, the dry products contain nitrogen, phosphorus, potassium, organic matter, amino acid, protein and other components.
The reason of fermentation in organic fertilizer production line
(1) In the fermentation process of organic fertilizer production line, the odor produced by compost should be prevented and controlled, and secondary pollution should be avoided. Adding fermentor or fast decomposing bacteria in compost can reduce odor in a short time, and the sensory effect is good. Or the odor produced by composting plant can be treated by biological deodorization technology.
On the one hand, the carbon nitrogen ratio, temperature, humidity, pH value, oxygen content and other nutrients needed for the growth and reproduction of each microorganism strain were satisfied by various factors; On the other hand, different nutrient content will produce different fertilizer effects.
For example, high carbon content can increase soil fungi, nitrogen elements help increase soil bacteria, and calcium has a significant effect on the resistance of crops.
(3) Strictly control the heavy metal content in raw materials to prevent microbial poisoning in the later production process, and the heavy metal content in the organic fertilizer products exceeds the standard, and pollutes the soil and crops.
(4) After analysis and detection, the content of trace elements such as organic matter, humic acid, nitrogen, phosphorus, potassium and the number of living bacteria should meet or exceed the national standards.
Different types and series of organic fertilizer machines will be equipped during the fertilizer manufacturing process. It will be equipped with a fermentation compost dumper to complete the fermentation process, and will be equipped with fertilizer mixer, fertilizer different types of crusher to deal with raw materials. There, if we produce bio organic fertilizer into granulator, we can use fertilizer granulator to complete the granulation process, design the type of fertilizer granulator into different types, and choose the appropriate type of fertilizer granulator to complete the granulation process.
For example, in the organic fertilizer production line, we can use drum granulator, disc granulator and new type organic fertilizer granulator to complete the production process, We can use the roller granulator to produce NPK fertilizer by extrusion. In the process of bio fertilizer production, the flat mold granulator can be selected to complete the production process and complete the granulation process. Different types of fertilizer granulator can be used in different types of fertilizer production process, and its working principle is different.
In order to achieve the goal of directional maturity and deodorization, we must also add microorganisms with specific functions to improve the effect of products. At present, bio organic fertilizer has been listed in the category of microbial fertilizer in the world, and more strict management measures are implemented than organic fertilizer to promote the healthy development of organic fertilizer.
China has a vast territory and rich raw material resources for organic compost equipment. It is understood that the final urine excreted by a pig in a year can be combined with bedding material to produce 2000-2500kg of high-quality organic compost, which is enough for one mu of land to use chemical compost throughout the year. The content of components is more than 6%, and the content of organic matter is more than 35%, which is higher than the national standard.
In the organic compost production line, we can use the drum granulator, or we can equip the drum granulator in the organic compost production line to complete the production process of NPK compost granulator. The granulation method completes the production process. This is different from rolling compost granulator, which usually uses dry granulation method to produce compost granulator.
In the bio organic compost production line, different types and series of compost equipment should be equipped to complete the production process. These machines play different roles in the compost manufacturing process.
In the production of compost granulator, the compost granulator should be designed and equipped on the production line to manufacture bio organic compost granulator. In the biological compost production line, we can use the flat mold granulator to manufacture the biological organic compost granulator, and we can also use the drum granulator. Complete the granulation process on the production line.
In addition, if you want to produce high quality NPK fertilizer granules in a simple step, our factory will provide you with fertilizer granule mixer. You just need to batch NPK fertilizer according to the formula, and then our bbfertilizer mixer will mix them evenly. Finally, you can get a good mix of NPK fertilizer particles.
What role does composter play in daily production, especially in composting? What kind of equipment is composter? The following is a brief introduction of organic fertilizer composter. Carry out daily production more effectively to improve economic benefits.
The organic fertilizer dumper has three main functions in the daily fertilizer manufacturing process
1. In the process of organic fertilizer tipping bucket, in the process of raw material compounding, various raw materials can be effectively integrated to make the raw materials fully integrated.
2. In the process of daily chemical fertilizer production, the organic fertilizer tipper can make the raw material fully contact with the air to adjust the temperature, and make it more fully ferment through continuous stirring.
3. The organic fertilizer hopper can change the permeability of raw materials in the mixing process, thus greatly improving the nutrition of raw materials.
In the whole compost fertilizer production process, the composter, which is usually used in the production line of organic fertilizer, helps to ferment the raw materials of organic fertilizer and plays the role of fermentation.
It is one of the indispensable equipment in the whole fermentation process. The use of equipment not only requires its excellent quality, but also requires a full understanding of the equipment and its use methods.
Only a deeper understanding of the equipment and the service life of the equipment, the final result can effectively increase profits, only faster and effectively improve production efficiency, can more directly increase revenue. Therefore, after purchasing fertilizer equipment, it is necessary to understand the use of the equipment and its role in the production process. Equipment.
The fertilizer machine manufacturer of the organic fertilizer production line will tell you the reason for the caking of organic fertilizer. The sx manufacturer of the organic fertilizer production line said in the last article that in fact, the premise of prevention is to find out the cause of caking. Everyont also knows that caking is not conducive to the use of organic fertilizer, and has a certain impact on the production and use of organic fertilizer. Want to answer why pig manure organic fertilizer production line caking.
We usually use the materials for fertilizer production, such as ammonium salt, phosphate, trace element salt, potassium salt, etc., most of which contain crystal water and are easy to absorb water and caking, such as ammonium sulfate, which is easy to caking in use. When urea meets with trace element salt, it is easy to agglomerate when releasing water, mainly because urea replaces trace element salt. The crystal water becomes mushy and agglomerates.
In the process of chemical fertilizer production, chemical fertilizer production is generally non closed. In the production process, the higher the air humidity is, the easier the fertilizer is to absorb water and caking. If the weather is dry or the raw materials are dry, the fertilizer will not agglomerate easily.
Organic fertilizer production line
The higher the room temperature of extruder granulator, the easier to dissolve. Generally speaking, raw materials will dissolve in their own crystal water, leading to caking. The higher the temperature of nitrogen, the water will evaporate and not caking easily. The temperature is usually higher than 50 ℃. We usually need heating to reach this temperature.
The greater the pressure applied on the fertilizer, the easier the contact between the crystals and the easier the agglomeration; the smaller the pressure applied, the less the agglomeration.
The longer the fertilizer is placed, the easier it is to agglomerate. The shorter the time, the less likely it is to agglomerate.
The organic fertilizer production line from sx organic machines is designed for the production of organic fertilizer granulator. In the process of organic fertilizer production, different types of fertilizer equipment are equipped to complete the production process. Here, we introduce the characteristics of organic fertilizer.
Among them, the technology of powdery organic fertilizer is relatively simple
1. Check the ingredients of your raw materials (such as plant ash, furfural residue, humic acid, etc.) to understand the accurate nutritional composition and proportion of each raw material, which plays an important role in the production of organic fertilizer;
2. The general production process of organic fertilizer requires the content of nitrogen, phosphorus and organic fertilizer granulator or disc granulator or roller granulator; the production process of organic fertilizer requires the content of nitrogen, phosphorus and potassium to be more than 4% and the content of organic matter to be more than 30%. So organic fertilizer can be mixed, crushed and packaged.
In addition, fertilizer equipment such as drum granulator, organic fertilizer granulator, disc granulator or roller granulator is required for organic fertilizer granules. The production of organic fertilizer requires the same raw materials as powder fertilizer, but after adding binder (bentonite or green palygorskite), the final particles need to be dried by rotary dryer.
Organic fertilizer production line
There is also an organic fertilizer with livestock manure, domestic waste and plant straw as the main raw materials.
The production process of the organic fertilizer is as follows: raw material drying, crushing, fermentation, mixing (mixed with chemical fertilizer). And other organic or inorganic substances, so that nitrogen, phosphorus, potassium content into particles (or not into particles, powder) and then packaging.
If the raw material is humic acid or peat, the organic fertilizer will not be fermented in the production process, and there is no need for fermentation. Other steps are the same as above.
As a professional fertilizer machinery manufacturer, we mainly produce all kinds of fertilizer equipment to complete the fertilizer production process. Our main products include not only fertilizer granulators, but also different types of fertilizer production lines.
With the continuous development of economy, various negative effects caused by environmental pollution also follow. If we can not solve the problem of air pollution for the time being, the consequences will be more serious. While bringing adverse effects to people’s lives, it also directly leads to more dangerous diseases, which makes more and more users use the production process of organic fertilizer and worries many manufacturers. At the same time, users themselves are more worried about this situation. How does the organic fertilizer machine, disposal , welcome go to https://www.wastetofertilizer.com/
The use of users is more concerned by enterprises. In the development of new products, also according to the use of improved. When tracking the after-sales situation, manufacturers usually send appropriate manpower to interview users who purchase organic fertilizer equipment, and record various situations encountered in use, so as to facilitate future production and provide corresponding opinions to users. The use of users directly leads to the research and development direction of new products.
The main problem occurs in the normal use of the process, so it is necessary to conduct proper after-sales tracking. We give users a certain sense of security, provide them with suitable NPK fertilizer granulator, let users know their own equipment, the error will be reduced to a small.
Since the mid-1980s, extrusion method has been greatly developed, and more and more industrial production equipment has been established in various places. Now, extrusion granulation compound fertilizer production line technology has become an international fertilizer research center. A new production technology of compound fertilizer was recommended.
Working principle of extrusion granulation of compound fertilizer production line:
The material is fed into a pair of counter rotating roll gaps (bite zones) of the roll granulator. To form a compact sheet of material under extrusion. After crushing and sieving the flake, the granular product with the required size can be obtained.
The formation mechanism of extruded pellets in compound fertilizer production line is as follows
At present, the general explanation of the material forming mechanism in the extrusion process is that after the material is compressed, the particles will be rearranged, and the air between the particles will be removed, so as to remove the voids in the material.
After further compression of the material, due to their different characteristics, the material particles will be in the following two situations: when the material is fragile, some particles will break, thus filling the remaining gap. In addition, if the atoms or molecules in the environment can not be rapidly decomposed into new particles, the free chemical bonds on the broken new surfaces will form strong recombination bonds when the new surfaces contact each other.
In the extrusion process of pelletizer used for fertilizer, the particles of material can also form solid bridge. The energy supplied to the system in the form of pressure will generate heat energy at the contact point of the material particles, thus melting the material. When the temperature of the material decreases, a solid bridge is formed.
Main equipment of extrusion granulation compound fertilizer production line
1. Forced feeder
One of the advances in extrusion granulation compound fertilizer production line technology is the use of forced feeding in fertilizer granulator, which is usually achieved by the driving force of screw. The extrusion process adopts the form of gravity free feeding.
Forced feed, easy to control the feed speed and reduce the slip phenomenon in the bite area. More importantly, the material can be partially degassed and compacted in advance in the forced feeder, thus greatly improving the product quality.
2. Crushing equipment
The flakes obtained by extrusion must undergo a so-called granulation process, such as crushing and sieving, to obtain the desired size of particles. The progress of pelletizing equipment is mainly due to a lot of experience gained in the relationship between the form of crushing equipment and products.
Zhengzhou SX Granulator Manufacturing Factory vigorously promotes energy-saving, environmental protection, high-efficiency new extrusion granulation compound fertilizer production line technology, and continuous progress and improvement.
The production process of organic fertilizer is suitable for the production of organic fertilizer in chicken manure, duck manure, goose manure, pig manure, cow manure, sheep manure, pigeon manure, rabbit manure and other common animal manure. If 10-20% plant straw is added, the effect will be better.
2. Production method: Sprinkle 20-30cm fertilizer. Sprinkle with grass powder, then sprinkle with manure thinner. Sprinkle fertilizer, rice straw powder and diluted bacterial solution again. After turning over, check the drying humidity of fermentation materials.
The drying humidity is about 60%, that is to say, hold the fermented material tightly with your hand, and feel the watermark on your hand, but there is no water drop. If the fermentation material is too dry, sprinkle appropriate amount of water when turning again. If the fermentation material is too wet, add dry manure or dry soil.
After mixing, pile up and cover with a layer of straw or film for fermentation. Use compost turning machine to process fermentation materials on time.
3. Fermentation time: 7-10 days in summer, 10-15 days in spring and autumn, and fermentation in plastic greenhouse in winter. The organic fertilizer after fermentation was dark brown, and the odor was reduced.
Fermented organic fertilizer
1. Mix the starter and fermentation material in proportion to start fermentation.
2. The fermentation process needs oxygen supply. Composting trucks are used to turn over materials and increase oxygen supply. Generally, fermentation can be completed in 5-7 days.
The organic fertilizer fermented in this way can be directly used as basic fertilizer for crops. If further treatment is carried out, other organic fertilizer equipment, granulator granulation, drying, cooling, bagging and selling as commercial fertilizer are required.

Microbial fertilizer can also be produced in the process of fertilizer manufacturing. As a new type of organic fertilizer, it can be produced through the production line of biological fertilizer, and its price is far higher than that of fertilizer and organic fertilizer. So almost all people who have used microbial fertilizer will choose to buy it again. What is the reason?
1. Deterioration of soil environment
The long-term use of single fertilizer leads to the deterioration of soil environment. Soil degradation will affect the reproductive and metabolic capacity of beneficial microorganisms and even lead to death. Some harmful microorganisms will take the opportunity to reproduce in large quantities. , invade the root of the plant and spread to the whole plant. Because of the growing of crops in soil, there are problems in the soil, which has a great influence on crops.
Most plants are suitable for the micro acid and micro alkali environment. However, the existence of a large number of acid ions makes the root system unable to absorb and secrete substances normally, which leads to the root nutrition can not keep up with, which affects the growth of the whole plant.
The utilization of fertilizer decreased. The long-term use of this fertilizer in fertilizer production leads to the deposition of a large number of elements such as phosphorus and potassium in the soil. When applied again, it will not be absorbed by the soil, but it will leach along the water, resulting in acidizing the soil environment.
2. The environment of Rhizosphere Microorganism worsens
Rhizosphere is a part of the soil micro soil region which is different from soil in physical, chemical and biological characteristics due to the influence of plant root activity. The difference between soil and soil is pH value, microbial activity change, etc. Here are solutions for you to make qualified bio fertilizer products.
The microorganisms that grow and propagate under the influence of plant roots in soil can transform organic matter into organic matter and provide nutrition for plants; meanwhile, they can secrete vitamins, etc., so as to promote the growth of plants.
The increase of acid iron content in soil will affect the change of micro ecological environment of roots, worsen the living environment of microorganisms, reduce the decomposition ability of organic matter and secretion, make the root malnourishment and affect the growth of plants.
Picture of NPK fertilizer production line and organic fertilizer production line to be designed:
3. Advantages of microbial fertilizer:
Microbial fertilizer is a product with special fertilizer effect caused by the life activities of microorganisms. It has many functions that other fertilizers do not have.
1) Improve soil fertility: nitrogen fixing microorganisms can increase nitrogen sources in soil; phosphorus and dissolved potassium microorganisms can decompose insoluble phosphorus in soil to absorb and use crops; in addition, the application of bacterial fertilizer can rapidly propagate and form a powerful beneficial plant flora, fundamentally improve the ecological structure of soil and make the hardened soil loose and permeable.
2) Enhance the resistance and worm resistance of crops: the growth and propagation of beneficial microorganisms in fertilizer can form the dominant population of the micro ecosystem of rhizosphere soil of crops, and inhabit the growth and reproduction of other harmful microorganisms; microorganisms can stimulate the growth of crops and improve the ability of agricultural products to resist adverse environment; the strains in fertilizer can induce the production of superoxide dismutase And eliminate the harmful factors in the environment, can improve the resistance of crops and reduce diseases.
3) Improve the ecological organic matter of crops. Microbial fertilizer can stimulate the fixed potassium, calcium, zinc and other micronutrients in the soil, and produce a variety of plant elements, stimulate and regulate the growth of crops, improve the quality of crops, improve taste and keep fresh. It is long and more resistant to storage.
Want to make bio fertilizer from manure wastes, here are guidelines for your reference.
Whether it is microbial fertilizer or organic fertilizer, we can design various fertilizer production lines through fertilizer equipment to produce various types of fertilizer. As a professional fertilizer mechanism manufacturer, we can not only produce organic fertilizer machine or NPK, but also can design different fertilizer production lines to produce various types of fertilizer granulator. For example, a bio fertilizer production line designed to produce a bio organic fertilizer granulator.
Processing sulfur coated urea in 15 t / h NPK fertilizer production line
Sulfur coated urea is a kind of coated slow release nitrogen fertilizer. In the process of NPK fertilizer production line, spherical urea is coated with a layer of molten sulfur to improve the physical properties of urea.
Sulfur coated urea is increasing in agricultural applications. With the increase of high concentration fertilizer application rate, the application amount of sulfur-containing super phosphate was relatively reduced, and the crop yield increased. The amount of desulfurization in soil increases, and the area of sulfur deficient land is expanding at home and abroad.
Therefore, the application of sulfur coated urea can not only improve the utilization rate of nitrogen, but also supplement the sulfur in soil.
Sulfur urea fertilizer production line equipment
Zhengzhou SX Heavy Industry Technology Co., Ltd. produces various NPK fertilizer production lines, organic fertilizer production lines and fertilizer granulation production lines. As shown in the figure, our plant specially designed a 15 t / h sulfur coated urea fertilizer production line. Sulfur urea production line equipment: 1 loader feeding hopper, 3 large angle belt conveyors, 1 rotary drum heater, 1 coating machine, 2 rotary drum powder machines and 1 fertilizer packaging machine for npk.
Processing technology of sulfur coated urea in NPK fertilizer production line
Urea particles are heated by a heater and then coated with a sulfur-containing outer film. After urea coating, it is sent to powder machine by large angle belt conveyor. The powder machine sprays particles to seal the cracks of the coating and reduce the biodegradation of the sulfur coating. Two series of machines are used to ensure the quality of fertilizer. The coating of NPK fertilizer production line on the outer layer of urea ensures the slow release of fertilizer efficiency.
The outer envelope provides a physical barrier for urea, so that urea is slowly permeated by water and decomposed by microorganism. In the soil environment, urea gradually diffuses through the envelope, and releases nutrients slowly through the envelope cracks and the structure formed naturally on the envelope surface.
Roller granulator is a new dry granulation process for compound fertilizer production. Drying and normal temperature process are not used in production. After molding, the powder material with water content less than 15% is compressed into pieces. After comminution, granulation and screening, the flake material becomes the granular material meeting the requirements of use.
The roller granulator is produced by a process without drying and normal temperature, forming a primary. The equipment has the advantages of less investment, quick effect and good economic benefit.
Production technology of compound fertilizer with roller granulator
1. The qualified raw materials are added into the mixer according to the proportion requirements and mixed evenly;
2. In the process of conveying, it is transported to the disc feeder to remove iron from the material;
3. The material in the disc feeder enters the fertilizer granulator evenly, and the material is forced to pass between the two pressure rollers and extrude into a thin plate. The thin plate is broken into pieces by the coarse crusher under the pressure roller, and the materials on the screen continue to be broken and screened;
4. The semi-finished products are transported to the finished product screening machine; after screening, the fine particles are directly returned to the disc feeder; the large particles are crushed by the pulverizer, and then returned to the disc feeder,
5. After screening, the qualified products are transported to the automatic packaging scale for weighing, packaging and storage
The shape and size of the ball on the drum skin can be selected in a wide range according to the needs of users. The spherical shape includes pillow shape, semicircular particle shape, rod shape, ball shape, walnut shape, flat spherical shape and square strip shape. At present, the shape of flat ball is adopted.
