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
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!
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.
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.
Raw materials for NPK fertilizer production: raw materials include urea, ammonium nitrate, ammonium chloride, ammonium phosphate, potassium, chloride, etc., which are provided in a certain proportion.
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.
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.
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.
At present, the growth of agricultural production generally depends on chemical fertilizer. On the one hand, it will cause environmental pollution. In fact, the non-point source pollution in rural areas is very serious, which has become a problem. On the other hand, it will affect the quality of agricultural products.
Therefore, people gradually realize that when using chemical fertilizer, we must increase the proportion of organic fertilizer, especially for vegetables, fruits, tobacco and other economic crops. The use of biological fertilizer can not only increase yield, but also improve quality and protect crops. Ecological environment, extensive use of municipal waste, sludge, livestock manure, orange and other waste. How to turn these organic materials into fertilizers, go to https://organicfertilizermachines.com/
The new technology of biological fertilizer production technology is used to produce biological fertilizer, which makes “grain fertilizer grain” form a virtuous circle chain. Therefore, biological fertilizer has become a new fertilizer and new fertilizer industry for the development of ecological home industry.
Organic fertilizer has the following characteristics:
1, rich in nutrients, high content, containing all kinds of nutrients needed for crop growth.
2. The effect of chemical fertilizer lasts for a long time, with both pre effect and post effect, which can fully meet the needs of various nutrients for crops in the whole growth period, but not in the late growth period. Interested in organic chemical fertilizer production？ Go here.
3. It is simple and convenient to use. It can be used as base fertilizer at one time. The method is simple, labor-saving and time-saving.
4. The cost is low, and the price of similar goods is the lowest.
5. High efficiency, input ratio is more than 1:10-30.
6. It is widely used in all kinds of soil and crops, including all kinds of greenhouse vegetables, fruit trees, cash crops, food crops, medicinal materials, flowers, lawns, seeds, etc.
Conditions for plant construction:
Reliability of raw material supply. The main raw material of this product is animal manure. Auxiliary materials include: peat, sawdust, straw, soybean cake, corn flour and other wastes. No more than 70 tons of raw material should be used per day.
Process of organic fertilizer production line:
The main ingredients include rice straw, pig manure, charcoal, etc.
The production process of organic fertilizer mainly includes: inoculation and fermentation of organic matter, main fermentation, crushing, ingredient mixing, drying, grading, cooling, screening, metering and packaging, etc.
In the granulation process, we need to pay attention to the design of different types of fertilizer models for different raw materials and fertilizer production lines. For example, in the organic fertilizer production line, we can use the disc granulator to produce the organic fertilizer granules, or we can choose the drum granulator, which is usually used in the NPK fertilizer manufacturing process to produce the compound fertilizer granulator to produce the organic fertilizer granulator Fertilizer granulator.
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.

When using a complete organic fertilizer production line to produce organic fertilizer granulator, it usually needs three parts. Share with you. For different types of organic fertilizer granulator or organic fertilizer powder plant, the fertilizer production process is different, and different types of fertilizer equipment are needed. Line.
There are two main parts of the equipment in the process of organic fertilizer production. Because of the relationship between production time, they are independent, interrelated and inseparable. The first part is the fermentation part, also known as the fermentation trilogy.
The main equipment sequence is: the first step is premixed equipment, which is based on the ratio of carbon to nitrogen, the ratio of carbon to phosphorus, the ratio of carbon to potassium, the mixture of water and bacteria; the second part is the flipping part, namely the equipment in the flipping fermentation tank, which is turned over according to the compost temperature, water content and air permeability in the fermentation tank; the trilogy is a refining equipment, also known as semi wet material crusher, which is carried out after fermentation Because mycelium is connected with each other, it is impossible to directly granulation, so special crusher is used for crushing.
The second part of the equipment is the granulation part. The main equipment includes automatic batching machine, pulverizer, granulator, dryer, cooler, screen separator, coating machine, automatic packaging machine, conveyor, auxiliary equipment, including induced draft fan, dust removal equipment, heating equipment, etc. are not very different from those in fertilizer manufacturing process. These two parts are independent, because fermentation takes a certain time and process. The granulation part requires a specific process.
These machines can be used in the production of NPK fertilizer in addition to the production line of organic fertilizer, but also for the production of NPK and compound fertilizer granulating machine. In addition to these types of fertilizer equipment used in the production line, there are other types of fertilizer. In designing fertilizer production line, we will design the appropriate fertilizer production line according to the type of raw materials and other factors.
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.
Drum granulator is the key equipment of NPK fertilizer granules production line, which is suitable for cold and hot granulation in large and medium-sized compound fertilizer plants. It and ordinary fertilizer granulator are wet granulation. By adding a certain amount of water and steam, the raw materials in the drum will become even and moist in the granulation process. Then, as the drum rotates, the material will combine and roll into particles. The fertilizer particles are spherical with a diameter of 3-4mm.

1. High granulation rate, drum granulator can adjust speed and control granulation.
2. Using solid granulation method, raw materials are easy to obtain and processing is relatively simple.
3. Liquid and steam injection is easy, and pipes and frames are provided.
4. Low investment, low production cost and high return.
5. The drum granulator uses the corrosion-resistant rubber engineering plastic as the lining to better protect the material from drum damage.
6. The particles produced belong to the secondary processing of base fertilizer, so there is almost no environmental pollution problem.
7. High quality steel and gear, stable operation, low noise.
8. Equipped with armrest shovel to help clean the roller.
After humidifying in the tank, use a certain amount of water or steam to make the basic fertilizer fully react. Under certain liquid phase conditions, with the help of the rotation of the cylinder, the material particles are extruded. The pressure condenses back into a ball.
The drum granulator of organic fertilizer equipment is filled with steam, ammonia or phosphoric acid or nitrogen solution, ammonia phosphorus slurry, and heavy calcium slurry to complete the chemical reaction and heating granulation process of compound fertilizer in the barrel; or a small amount of water is added to make the compound fertilizer cold granulation.
The material to be pelleted is rotated through the cylinder and bonded to form a ball under certain humidity and temperature to complete the pelleting process.
In the pelletizing process of drum fertilizer granulator, the powder material is mainly cladding type, so the material circulation volume needs to be large, so that the material can form large particles in the cladding process. When the water content in the material is large, the water injection should be reduced to make the fertilizer made into granules absorb less water.
When granulating with this combination method, if the water content in the material is small, more water injection is needed. Because the materials are combined with each other, the gap between the powder particles needs to be filled with water. As the understanding of granulation process has been deepened, some suitable monitoring tools have been developed, so the granulation process can be simulated and controlled automatically by computer.
What is bio organic fertilizer granulator? What is the difference between NPK and NPK? What are the advantages of bio organic fertilizer granulator? In this article, we get the answer.
What machines can be used for bio fertilizer granulation?
Bio organic fertilizer refers to the combination of specific functional microorganisms and organic matter, which is mainly composed of animal and plant residues (such as livestock manure, crop straw, etc.), and organic matter after harmless treatment and decomposition. Fertilizer has the function of increasing fertilizer.
The use of bio organic fertilizer is also different, and the nutrients of bio organic fertilizer are complete. Chemical fertilizer is only one or several nutrients of fertilizer. Bio organic fertilizer can improve the quality of products; bio organic fertilizer can improve the rhizosphere microflora of crops and improve the ability of plants to resist diseases and pests. Chemical fertilizer is a single crop microorganism, which is easy to produce diseases and pests. Bio organic fertilizer can improve the rhizosphere microflora of crops and improve the ability of plants to resist diseases and pests. Chemical fertilizer is a single crop microorganism, easy to produce diseases and pests.
Difference in manufacturing process
Finally, the manufacturing process is much simpler. Because the biological fertilizer granulator equipment is also a kind of organic fertilizer granulator, the organic fertilizer granulator sometimes needs drying and cooling.
What are the advantages of bio organic fertilizer granulator?
1. Bio organic fertilizer is completely decomposed without burning roots or rotting seedlings; refined organic fertilizer is not decomposed and directly decomposed in soil after use, which may cause combustion.
2. Bio organic fertilizer decomposes at high temperature, killing most pathogens and eggs, reducing the occurrence of diseases and pests
3. Adding beneficial bacteria to bio organic fertilizer can reduce the diseases caused by the occupation of bacteria
4. Bio organic fertilizer has high nutrient content, and its odor is light and almost tasteless after deodorization.
The fertilizer machine manufacturer not only designed two kinds of fertilizer production lines, but also designed the organic fertilizer production process to produce the organic fertilizer granulator.
