Particle drying is an essential step in the production line of nitrogen, phosphorus and potassium fertilizer. The state requires that the moisture content of compound fertilizer must be less than 30% to meet the national standard. Then in the process of compound fertilizer production, the water content of organic fertilizer after granulation reaches about 50%.
Sometimes even higher, the moisture content of dry particles has become an important link in fertilizer production.
In the drying process of fertilizer manufacturing process, it is very important to pay attention to the drying method. The fertilizer produced by the compound fertilizer equipment is full dry fertilizer. So how does compound fertilizer equipment produce dry fertilizer? What are the methods?
1. Mechanical dewatering method: mechanical dewatering method is to pressurize materials and then extrude some water. Common methods include pressing, sedimentation, filtration, centrifugation, etc. Mechanical dehydration is only used for the initial dehydration of raw materials. This method is not suitable for the production of particles.
Therefore, the moisture content of materials after mechanical dehydration is still high, generally 40-60%. However, mechanical dehydration is the most economical method, which is most suitable for the dehydration of poultry and animal feces.
2. Heating and drying method of compound fertilizer dryer: This is what we often call drum dryer drying method. It uses heat energy to enter the dryer barrel, and the temperature in the barrel reaches about 150 degrees. According to different materials, the temperature can be adjusted to evaporate the water in the materials.
A certain amount of heat energy is required to remove the water in the materials. This method usually uses air to dry the material. The air is preheated and sent to the dryer to transfer heat to the material, so that the water in the material evaporates to form water vapor, which is brought out of the dryer with the air.
The material can be heated and dried to remove the combined water in the material, so as to achieve the water content required by the product or raw material. This method can be applied to a variety of industries, and it is also one of the simplest methods to meet the requirements.
3. Chemical dehumidification method: this method uses hygroscopic agent to remove a small amount of moisture in gas, liquid and solid materials. Due to the limited dehumidification capacity of hygroscopic agent, it is now only used to remove trace moisture in materials. Therefore, this method is rarely used in production.
Typical application materials: chicken manure, pig manure, cow manure, charcoal, clay, kaolin, etc. This machine is most suitable for direct granulation of organic fertilizer after fermentation, eliminating the drying process and greatly reducing the manufacturing cost.
The new organic fertilizer granulator uses the mechanical stirring force of high-speed rotation and the generated aerodynamic force to continuously mix, granulate, spheroidize and densify the fine powder materials in the machine, so as to achieve the purpose of granulation. The particle shape is spherical, the sphericity is ≥ 0.7, the particle size is generally between 0.3-3mm, and the granulation rate is ≥ 90%.
Organic fertilizer raw materials (animal manure, domestic waste, dead leaves, biogas residue, waste bacteria, etc.) are fermented into a semi wet material crusher for crushing, and then nitrogen, phosphorus, potassium and other elements (pure nitrogen, phosphorus pentoxide, potassium chloride, ammonium chloride, etc.) are added to make the mineral elements meet the specified standards, then stirred with a mixer, and then enter the granules of the new organic fertilizer granulation mechanism.
After drying, the screened qualified products are packaged by the screening machine, and the unqualified products are returned to the granulator for granulation.
Now this new type of organic fertilizer wet granulator is deeply loved by the majority of users. Our wet organic fertilizer granulator is in short supply. The birth of new products, new fertilizer manufacturing technology, energy conservation and environmental protection, trustworthy.
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.
The technical content of biological fertilizer project is high. In addition to the biological agents that promote the maturation and decomposition of organic matter in the maturation process, in order to achieve targeted maturation and deodorization, microbial products with specific functions need to be added to enhance the effect of the products.
At present, bio organic fertilizer is included in the category of microbial fertilizer in China, and more strict management measures are implemented than organic fertilizer to promote the healthy development of organic fertilizer.
1. The production process of bio organic fertilizer production enterprises registered with the Ministry of agriculture is basically engaged in the production of microbial fertilizer. In the process of fermentation production, tank stacked fermentation is mostly used, and there are other fermentation methods, such as flat stacked fermentation and fermentor fermentation.
In the process of fermentation and maturation, the adjustment of material moisture, carbon nitrogen ratio and temperature and the use of curing agent are the production process. The key is that the application of fungicide directly affects the fermentation cycle and the maturity of materials. The ripening material basically achieves the harmlessness of the product and is also conducive to the survival of the functional bacteria added in the post-treatment process.
2. In terms of post-treatment of fermentation materials, most enterprises add functional bacteria for compound molding. The dosage form of the product is mainly powder, and some are granulated by rotary drum fertilizer granulator or roller granulator. Granular products prevail over powdered products. The disadvantages of poor appearance and low grade not only improve the commerciality of the product, but also increase the production cost of the enterprise, which has a certain impact on the survival of effective bacteria.
3. The utilization of strains and microbial strains is the core of bio organic fertilizer products. In the production process, there are generally two links related to the utilization of microorganisms:
First, add decomposition bactericide to promote material decomposition and decompose and deodorize in the decomposition process. It is mainly composed of complex strains.
Common strains include photosynthetic bacteria, lactic acid bacteria, yeasts, actinomycetes, Penicillium, wood fungi, etc; Second, the functional bacteria added after material decomposition, generally nitrogen fixing bacteria, phosphorus solubilizing bacteria, silicate bacteria, lactic acid bacteria, Pseudomonas, actinomycetes, etc., play a specific role as fertilizer in the product.
Therefore, the selection and use of microbial strains for the production of bio organic fertilizer is a core technology. Only by mastering this key technology can we accelerate the decomposition and maturity of materials, Ensure the application effect of the product.
4. Ignite the hot air oven to preheat the dryer and start the dryer at the same time. Do not rotate the cylinder to prevent the cylinder from bending.
5. According to the preheating condition, the wet material is gradually added into the drying cylinder, and the feeding amount is gradually increased according to the moisture content of the discharged material.
6. The preheating of the dryer needs a process, and the hot blast stove should also have a preheating process. Sudden fire is prohibited. Prevent local overheating and uneven thermal expansion and damage.
7. Fuel combustion value, thermal insulation quality of each part, moisture content of wet material and uniformity of feeding amount affect dry product quality and fuel consumption. Therefore, it is an effective way to improve economic benefits to make each part reach the state as much as possible.
8. In the working state, the roller frame shall be filled with cooling water.
9. All lubricating parts shall be filled in time.
10. During shutdown, the hot blast stove shall be closed first, and the drying cylinder shall continue to rotate until it is cooled to close to the outside temperature.
Any material applied to the soil or sprayed on the ground of crops, which can directly or indirectly supply nutrients to crops, increase crop yield, improve product quality or soil properties, and make the soil fertile, is called fertilizer. Fertilizers that directly provide essential nutrients for crops are called direct fertilizers, such as nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer, trace element fertilizer and compound fertilizer.
Other fertilizers, mainly used to improve the physical, chemical and biological properties of the soil, so as to improve the growth conditions of crops, are called indirect fertilizers, such as lime, gypsum and bacterial fertilizers.

According to chemical composition, fertilizers can be divided into organic fertilizer and chemical fertilizer. Today I will introduce the basic information of organic fertilizer and chemical fertilizer.
Organic fertilizer is a kind of natural fertilizer which is used in rural areas, such as animal and plant residues or human and animal manure, and applied in situ or planted directly. It is also called farmyard manure.
What is chemical fertilizer? How to make chemical fertilizer by your own? Go to https://www.fertilizer-plants.com/compound-fertilizer-production-line/ for more.
In a narrow sense, chemical fertilizer refers to chemical fertilizer; In a broad sense, chemical fertilizer refers to all inorganic fertilizers and slow effect fertilizers produced in industry. Therefore, some people only call nitrogen fertilizer, but it is not comprehensive to call chemical fertilizer. Fertilizer is the general term of nitrogen, phosphorus, potassium and compound fertilizer.
In chemical fertilizer, the fertilizer containing two or more main nutrients such as nitrogen, phosphorus and potassium is called compound fertilizer. Therefore, NPK compound fertilizer is a kind of chemical fertilizer.
Our factory mainly produces organic fertilizer production and NPK fertilizer production equipment, such as dumper, mixer, crusher, granulator, etc.
1. Before transplanting, plant according to the standard, the aperture (top) is 13-15cm, 10-12cm, mix the fertilizer used in the whole growth period, evenly apply it to the bottom of the fertilizing hole, dig the pool for 8 times, fertilize – 10cm in front of the hole, transplant cabbage seedlings, and cover the soil with fertilizer by the way.
The distance between root planting and hole fertilization is always 8-10cm, which is easy to absorb and will not cause seedling burning.
2. After transplanting or 15-20 days after transplanting, a fertilizing hole with a depth of 13-15cm and a diameter of 10-12cm was dug in the center of every 4 plants. During the whole growth period, all the chemical fertilizers were mixed evenly and then applied to the bottom of each fertilizing hole, and the soil was immediately covered.
Cabbage in the preparation, the whole growth period of fertilizer should be fully mixed, evenly spread on the cultivated land, through repeated rake, fertilizer soil fully mixed, to achieve the whole surface soil fertilizer mixed, the preparation and transplanting.
Now, let me introduce the drum granulator.
Working principle of drum granulator:
The working principle of this series of drum granulator is: the main motor drives the belt and pulley, which are driven to the transmission shaft through the reducer, and work together through the open shaft installed on the gear and the large gear teeth fixed on the body.
The material is fed from the feeding end through the cylinder. Through the function of the internal structure of the cylinder, the particles are made and finally come out through the air outlet. With the continuous entry of materials, the continuous rotation of granulator, in order to achieve mass production.
This machine is the main machine of NPK fertilizer production line.
Advantages of NPK fertilizer production line:
1. Raw materials are widely used
2. The spheroidization rate is high and the survival rate of biological bacteria is high.
3. The process is short
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.
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.
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/
The special granulator for organic fertilizer is a kind of fertilizer granulator. After fermentation, it is used for pelleting various organic substances. There is no need to dry and crush raw materials before granulation. Spherical particles can be directly processed by batching, which can save a lot of energy.
Organic fertilizer granulation equipment is an important equipment in organic fertilizer production line. If the production of granular organic fertilizer is not good, it will directly affect the quality and effect of organic fertilizer. Then the granulator of organic fertilizer should pay attention to the production of organic fertilizer. Do you have any details?
1. The organic fertilizer granulator shall be equipped with two powder boxes for granulation, so that the granulator does not need to stop when changing the formula.
5. The finished granular organic fertilizer should be packed in the finished product warehouse. Pay attention to the storage environment, so as not to affect the use effect of organic fertilizer.
The above are some details that should be paid attention to during the operation of organic fertilizer granulator. It not only saves a small amount of power input, but also effectively reduces the cost, and improves the efficiency, convenience and speed of the task.
The new organic fertilizer granulator also realizes higher organic content and the exclusive production of pure organic fertilizer.ra
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.
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.

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!
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.

2. Raw material mixing: evenly mixing the prepared raw materials to improve the uniform fertilizer efficiency of the whole fertilizer particles. In the production of NPK fertilizer granulator, roller granulator can be used to complete the fertilizer production process.
And series fertilizer equipment can also be used in the production process of organic fertilizer.
Bio organic fertilizer production line technology is a kind of organic fertilizer produced by harmless treatment of specific functional microorganisms and mainly from animal and plant residues (such as livestock manure, crop straw, etc.) and fermentation equipment.
Organic materials. It is a kind of fertilizer with the function of both microbial fertilizer and organic fertilizer. Organic fertilizer produced by biological organic fertilizer production line equipment contains a variety of nutrients, nutrient balance, and fertilizer use time is long. Organic fertilizer contains a large number of beneficial microorganisms, which can promote the biotransformation process in the soil, and is conducive to the continuous improvement of soil fertility.
Bio organic fertilizer production line technology. Organic fertilizer granulator equipment can be used as a stirring toothed granulator. By using the high-speed rotating mechanical stirring force, the resulting aerodynamic force and the resulting aerodynamic force, the fine powder material can enter the machine continuously to realize the mixing process, granulation, spheroidization and densification, so as to achieve the purpose of granulation.
Pay attention to the use of bio organic fertilizer manufacturing equipment:
1. It is forbidden to put iron, stone, wood and other sundries into the machine to avoid damaging the equipment. During granulation, it is forbidden for the pressing roller and the template to contact idling.
2. If the particles are cracked or compressed insufficiently, the coarse fiber material formula should be reduced to less than 50%.
3. When pelleting occurs, if there is no pelleting or organic fertilizer is not discharged, the template should be replaced, and some fiber materials can be added to restart pelleting.
4. Check the belt tightness frequently. If the transmission leaks oil, replace the oil seal in time.
Due to the integrity of various nutrients in organic fertilizer, and these substances are completely non-toxic, harmless and pollution-free natural substances, it provides the necessary conditions for the production of high-yield green food. Organic fertilizer contains many kinds of sugars. The use of organic fertilizer will increase the kinds of sugars in the soil. For carbohydrates, with the release of a large amount of energy in the process of organic matter degradation, the growth, development and reproduction of soil microorganisms have energy. More info on bio fertilizer production, go here.
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.
Granulators used to convert organic fertilizer into thread and teeth can make various materials into specific shapes. This is a special molding equipment. The equipment uses the aerodynamic force formed by the internal high-speed rotating mixer to realize the mixing, spheroidizing and densification process of fine powder in the machine.
Conversion granulation is the wet granulation of agglomerates by a certain amount of water or steam, so after adjusting the humidity, the basic fertilizer will have a complete chemical reaction in the barrel. Under certain liquid conditions, the rotation of the barrel will squeeze the material particles. The pressure condenses back into a ball.
The combination of the two granulation methods makes the prepared particles have higher sphericity and more beautiful appearance. At the same time, it saves energy and has high energy efficiency.
Main features of drum granulator:
1) Low investment, good economic benefit and reliable performance;
2) Low energy consumption, no three wastes emission, stable operation, convenient maintenance, reasonable process layout, advanced process and low production cost;
3) The ball has high strength, good appearance quality, corrosion resistance, wear resistance and low energy consumption;
The working principle of the drum granulator is that the belt and pulley are driven by the main motor and transmitted to the drive shaft through the reducer. The driving gear meshed with the big gear ring is fixed on the vehicle body. Work with each other.
Material is added from the feed end through the cylinder. Through the function of the special structure inside the cylinder, it is made into particles, and then flows out through the outlet. Due to the continuous entry of materials and continuous rotation of granulator, mass production can be realized.
The whole fertilizer granulator can be divided into five parts
1) Support: the whole rotating part of the organic fertilizer drum granulator is supported by the support, which bears greater force. Therefore, the supporting wheel frame of the machine is welded with medium carbon steel plate and channel steel, which has passed the strict quality control and special process requirements and achieved the purpose of the machine.
In addition to fixing the bracket on the shelf, considering that it will cause greater friction with the rolling belt of the car body, our factory specially selects anti-corrosion and wear-resistant materials to greatly extend the service life of the machine. Casting integration technology is also used. In addition, there are hooks on the four corners of the roller carrier, which is convenient for loading and unloading.
2) Transmission part: the transmission part of the whole granulator is very important to the whole body. The transmission frame is welded by channel steel and has passed the strict quality requirements. Installed on the gearbox, the main motor and reducer of our company use ISO products with reliable performance and reliable quality. The motor drives the pulley, V-belt and reducer to the spindle to make the body work. The transmission reducer is connected with the working parts of the main shaft through a nylon shaft pin connector.
3) Big gear: fixed on the body, with gear pinion, the opposite drive body work, using high-tech wear-resistant materials, so that the service life of the machine is longer.
4) Rolling belt: fixed on both sides of the fuselage, supporting the whole fuselage.
5) Body part: the body part of the whole granulator is particularly important. It uses high-quality medium carbon steel plate, built-in special rubber lining or acid resistant stainless steel lining for welding, in order to achieve automatic scar removal and tumor removal, eliminating the traditional scraper equipment, and through strict quality control and special process requirements, to achieve the purpose of this machine.
The production of organic fertilizer or bio fertilizer granulating machine can use fertilizer manufacturing technology, and a complete fertilizer production line is designed to produce pelletizer, and different types of fertilizer machines are equipped in the process of fertilizer manufacturing.
The so-called bio organic fertilizer production line is actually the ordinary organic fertilizer production line. The main reason for the difference between biology and common organisms is that in the process of production, the production line of bio organic fertilizer increases the link of adding microbial agents, which leads to the final production of organic fertilizer and bio organic fertilizer.
The production line is organic fertilizer fermentation. In order to better explain the difference between the two production lines, let us first understand the difference between the production process of organic fertilizer and the production process of biological organic fertilizer.
Flow flow of organic fertilizer production line:
The basic process of the production line is as follows: the use of fermentation compost dumper to collect raw materials, and then stack and ferment raw materials can save more time. Next, the raw materials are crushed by the fertilizer pulverizer, and then screened by the screening machine. Raw material, then premixed. Next, the granulator is made by a fertilizer granulator. After granulation, the granulator is treated with a dryer and a cooling machine. Finally, the screening machine is used to screen and pack the high quality fertilizer.
Process flow of bio fertilizer production line:
In the process of bio organic fertilizer production line, raw materials shall be collected first, then bio fermentation with organic fertilizer starter shall be used to complete fermentation of semi-finished organic fertilizer products, then premixes shall be crushed and then pelletized, and then the granulator shall be dried and cooled by the fertilizer dryer dryer and cooling machine. Finally, the second screen and the pelletizer are packed.
From the above two kinds of organic fertilizer production, we can see that fermentation is the first and most important link of organic fertilizer production, because the final use effect of the organic fertilizer is in this link.
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.
1. In the solid granulation process of rotary drum granulator, urea, ammonium chloride, ammonium sulfate, potassium chloride and other single base fertilizers are used as raw materials and mixed in a certain proportion (mainly determined by the local market demand and soil test results)).
3. The material is sent to the drum granulator by belt conveyor, and agglomerates to form particles through a series of humidification and heating processes.
4. The particles here are only semi-finished products. They need further treatment, including drying, screening, cooling and packaging. After all these steps, high quality compound fertilizer products can be obtained.
