NPK fertilizer production line of roller extrusion granulator is widely used in powder processing. It is characterized by no need to humidify or heat the material, and the material can be directly processed into particles. It can be used for organic and inorganic fertilizer granules, as well as for the processing of feed granules.
NPK fertilizer production line adopts dry extrusion granulation process. There is no waste water, no waste gas emission and no environmental pollution. Extrusion granulation process is short, easy to operate, easy to realize automatic production control, and improve the production efficiency. There are no special requirements for the properties and particle size distribution of raw materials, so the sources of raw materials are relatively wide.

NPK fertilizer production line of roller extrusion granulator
1. According to the proportion requirements, add qualified raw materials into the mixer and mix them evenly.
2. Transfer to the disc feeder and remove metal material from the material during transmission.
3. The materials in the disc feeder evenly enter the extrusion fertilizer granulator machine. The material is forced to pass between two pressure rollers and is pressed into thin sheets. The flakes are broken into pieces by the coarse crusher under the action of the pressure roller. Sieving. The sieve material continues to be crushed and sieved.
4. Transport the semi-finished products to the finished product screening machine. The screened fine particles are directly returned to the disc feeder. The large particles are crushed by the mill and then returned to the disc feeder.
5. The screened qualified products will be transported to the automatic packaging scale for weighing, packaging and storage.

Once the diameter of the disc is determined, the height of the disc can basically be determined. Generally speaking, the larger the diameter, the higher the height of the disc. However, the height of the disc can affect the ball time of the fertilizer on the disc. The particles generated on the disc will be affected by the friction coefficient between the raw material and the disc surface. The difference produces a grading effect. Small particles stay close to the bottom of the disc, while larger particles are discharged beyond the edge. The higher the disc edge, the longer the ball formation time. The disc granulator is an organic fertilizer granulator. If the height of the disc is too low, the pelletizing time will be short, and the particles that come out are relatively small in size. Therefore, on the one hand, the height of the pan can affect the size of the particles discharged from the pelletizing pan, and on the other hand, it can also affect the output. Because if the material stays in the pan for too long, the discharge speed of the product will be slower, the larger the particles of the product, the more particles that do not meet the standard, and the lower the rate of ball formation. Therefore, it is reasonable to choose a high plate height. important.

In the fertilizer production process, since the particles will gradually grow up as they roll down along the surface of the disc, the more the material rolls in the disc per unit time, the faster the particles will grow up, that is, the working efficiency of the granulator It is proportional to the speed of the granulator. Because the basic powder fertilizer rises with the rotation of the disc with a certain slope, it rolls down under the action of gravity, and at the same time, it is thrown to the edge of the disc due to the centrifugal force, these powders collide and fuse with each other, and The liquid phase is bonded together by the surface tension. Therefore, the speed of the speed will affect the bonding and pelletizing process of the powder-grain fertilizer on the one hand. If the rotation speed is too fast, the powder fertilizer will not be formed in time, and it will be thrown out of the disc; too slow rotation speed will cause the powder particles to form a ball for too long, making the diameter of the particles overflowing the disc larger than the standard requirement; on the other hand, with the disc As the inclination angle increases, if the rotation speed of the disc is too slow, the material will accumulate in the lower part of the disc, and the drop and repeated rolling up and down will not occur, which will also affect the ball formation rate. We have some types of organic fertilizer machine.

As the speed of the pelletizing disc increases, the centrifugal force increases, which will make the particles close to the edge of the disc, preventing the particles from rolling down, and a funnel-shaped vortex will appear on the disc surface. In order to maintain the effective use of the disk surface area, the inclination angle of the disk must be increased while increasing the speed. As the inclination angle of the disc increases, the end speed of the particle rolling will increase accordingly, so the inclination angle of the disc should be maintained at a limit value to prevent damage to the rolling and granulation of the material. Therefore, the rotational speed of the disc is also a major influencing factor.

In the organic fertilizer production process, the material pelletized by the disc is generally fermented, and the fermentation tool used at this time is a compost windrow turner.

 How to properly install and use the organic fertilizer granulator?

People’s life water product increase gradually in recent years, is becoming more and more strict to the requirement of quality of life, just want to eat food, now attaches great importance to the green food, use too much synthetic fertilizers will inevitably remain some chemicals, affect the health of the people, the organic fertilizer in at this time appear in people’s field of vision is very heavy, is more and more attention and recognition, therefore organic fertilizer granulator sales, in short supply, the following is a heavy industry give you a summary of organic fertilizer granulator installation when using the matters needing attention.

1, organic fertilizer granulation machine installation should pay attention to balance, installed on the flat ground, the foot is fixed, fixed is not in the work of shaking accidents.

2. Pay attention to the horizontal vertical between the main engine and the ground during installation.

3. After installation, please check whether the screws of the machine are loose and whether the door air cabinet of the main engine barn is fastened. If so, please reinforce it to avoid accidents.

4. Connect the wires of the machine according to the instructions, and check whether the control switch is in good condition.

5. Test some aspects of the machine before use, and the production can be carried out after normal test run.

6, fertilizer granulator is the most important fertilizer equipment in the fertilizer production process, some fertilizer granulator can only be used for organic fertilizer granulator, but some fertilizer granulator can not only for organic fertilizer granulator can also be compound fertilizer granulator.

Organic fertilizer granulator includes flat mold organic fertilizer granulator, ring mold organic fertilizer granulator, double roller organic fertilizer granulator, hammer type organic fertilizer granulator, disc type organic fertilizer granulator, drum type organic fertilizer granulator Fertilizer granulator, drum type organic fertilizer granulator, etc., almost include all organic fertilizer granulators except tower granulation and condensation granulation, covering the common organic fertilizer granulation in the industry equipment. In fact, organic fertilizer powder is the best suitable fertilizer for crops. This kind of fertilizer has a simple production process, low processing cost, less harmful ingredients, and fast absorption by crops. However, with the popularization of mechanized fertilization and the existence of powder transportation People are slowly approaching organic fertilizer granulation because of the disadvantages of this. Therefore, the organic fertilizer granulator was born.The traditional organic fertilizer granulator is a disc-type organic fertilizer granulator, a drum-type organic fertilizer granulator, and a drum-type organic fertilizer granulator. These equipment play the role of connecting the past and the future for the later organic fertilizer machine. It has made great contributions to the accumulation of experience in organic fertilizer granulators. The advantages of disc granulator, drum granulator and drum type organic fertilizer granulator are simple process, convenient operation, less equipment failure and high output, but these organic fertilizer granulators have high moisture content in the finished granules. , Small particle density, high bagging rate of broken, high dust content during processing, uneven particle size and other defects. Through these defects, people gradually carried out equipment transformation and renewal.

The common organic fertilizer granulator on the market now is a combination of a flat die organic fertilizer granulator and a disc-type organic fertilizer granulator. The flat mold organic fertilizer granulator has the characteristics of high pressure, easy adjustment of the gap of the mold pressing wheel, high density of pressed particles, low dust content in the working environment, low particle moisture content, and easy drying of the finished product. The granulator can only compress columnar granules and is almost powerless for machine-seeded spherical granules. Combining the flat mold organic fertilizer granulator and the disc-type organic fertilizer granulator can reflect the superiority of the production of organic fertilizer particles, especially spherical particles. The basic use process is to use the rotation of the disc organic fertilizer granulator to polish and polish the columnar particles extruded by the flat-die organic fertilizer granulator, and finally produce spherical organic fertilizer particles. Different fertilizer granulators are selected for different fertilizer production process.

The role of bio-organic fertilizers Bio-organic fertilizers have different functions due to the different types of microorganisms contained. In summary, they have the following effects.

⑴ Nitrogen fixation, such as root nodules and nitrogen-fixing bacteria, they can fix nitrogen in the air under suitable environmental conditions and provide nitrogen nutrition for crop growth. It is estimated that the annual biological fixation of nitrogen by crops can reach 101 million tons.

⑵Nutrient release effect Microorganisms decompose some substances in the soil that are difficult to be absorbed and utilized by crops and convert them into effective nutrients that can be absorbed and utilized by crops. For example, silicate bacteria can not only decompose difficult-to-decompose minerals such as potassium feldspar and mica in the soil, and release the fixed potassium, but also promote the conversion of insoluble phosphorus in the soil into a form that can be used by crops.

⑶ Growth-promoting effect After applying microbial fertilizer to the soil, it not only increases the nutrient content in the soil, but also promotes the synthesis of various vitamins, enzymes and other substances beneficial to crop growth, stimulates the growth of crops, and assists crops in absorbing nutrients. In the fertilizer production process, the addition of biological agents is before the fertilizer packaging.

⑷Disease resistance After some microorganisms are inoculated in the soil, they multiply in the roots of crops and become the dominant bacteria in the rhizosphere of the crops for a period of time, inhibiting or reducing the reproduction opportunities of pathogenic microorganisms, and some microorganisms will also have resistance to pathogenic microorganisms. Although microbial fertilizer can provide nutrients for crop growth and stimulate and promote crop growth, its role is still limited after all. In crop production, organic fertilizers and chemical fertilizers are mainly used to provide nutrients for crop growth. According to the different organic fertilizer materials, the selected organic fertilizer granulator is also different.

⑸Many raw materials in nature contain many beneficial microorganisms, but once these raw materials are applied to the soil, the microorganisms in them will be eaten by countless microorganisms in the soil. Therefore, it cannot survive stably in the soil, and its effect is difficult to show. However, if the beneficial bacteria are added to the fermented organic fertilizer after fermentation, the fermented organic fertilizer itself is the expansion medium, which will cause the bacteria to proliferate in large numbers. At this time, applying microbial organic fertilizer to the soil will quickly form a dominant population in the soil, which can play a good role in the root system of the crop. Fermented organic fertilizer has a good effect on exerting microbial activity. Welcome to buy our company’s organic fertilizer machine.

In many farms, pig manure is dirty and odorous, making it difficult to treat. However, pig manure is actually a very good organic fertilizer material, which is rich in a large amount of organic matter and nutrients required for making organic fertilizers. The pig manure organic fertilizer production line is a series of production equipment that uses pig manure as raw material and ferments and processes it through organic fertilizer equipment to produce organic fertilizer. It is equipped with equipment such as fermentation tipping machine, organic fertilizer crusher, horizontal mixer, organic fertilizer granulator, rotary dryer, cooling machine, drum screening machine, coating machine, packaging machine, and belt conveyor. Using pig manure organic fertilizer production line to process commercial organic fertilizer requires three steps: pre fermentation, deep processing powder making, and deep processing granulation.

The workflow of pig manure organic fertilizer production line:

1. Raw material fermentation, using a fermentation tipping machine to flip and toss the raw materials during the fermentation process irregularly.

2. Use a forklift to shovel the fermented raw materials into the silo, where they are transported by a belt conveyor to a semi wet material crusher for crushing.

3. The crushed material is transported to the organic fertilizer horizontal mixer through a belt conveyor, where the raw materials and auxiliary materials are uniformly blended and then transported to the granulator through a belt conveyor.

4. The granulator converts raw materials into particles and then sends them to a drum dryer through a belt conveyor. After drying, the materials are sent to a cooling machine through a belt conveyor for cooling.

5. The cooled particles are fed into the screening equipment through a belt conveyor, which has three discharge ports: small particles, qualified particles, and large particles. Small particles are returned to the granulation process through a belt conveyor, while large particles are fed into the crushing process through a belt conveyor. Qualified particles are fed into the organic fertilizer automatic packaging machine through a belt conveyor and packaged into bags.

Organic fertilizer equipment can effectively solve the environmental pollution caused by organic waste in industries such as livestock and poultry breeding, reduce the eutrophication of surface water caused by pollution, improve the safety and quality of agricultural products, and lay a good foundation for human comprehensive consumption of green and organic food. The ecological and environmental benefits are quite significant. The pig manure organic fertilizer production line has a high degree of automation and smooth production rhythm, which not only improves work efficiency but also saves a lot of manual labor. Pig manure organic fertilizer can improve the chemical and biological characteristics of soil, improve soil water retention, fertilizer retention, and permeability, and the profit per ton ranges from 300 to 500 yuan.

Compound fertilizer granulator is a molding machine that can manufacture materials into specific shapes. Compound fertilizer granulator is one of the key equipment in the compound fertilizer industry, suitable for cold and hot granulation, as well as large-scale production of high, medium and low concentration compound fertilizers. The main working method is wet granulation of pellets. By using a certain amount of water or steam, the basic fertilizer is humidified in the cylinder and undergoes a thorough chemical reaction. Under certain liquid phase conditions, with the help of the rotational motion of the cylinder, the material particles are squeezed and agglomerated into balls. The cylinder of this machine is lined with special rubber plates or acid resistant stainless steel plates, achieving automatic scar removal and tumor removal, eliminating the traditional scraper device. This machine has the characteristics of high ball forming strength, good appearance quality, corrosion resistance, wear resistance, low energy consumption, long service life, and convenient operation and maintenance.

What are the common production methods of compound fertilizer?

1. Production of compound fertilizer. Put pork ribs, lamb ribs, short ribs, etc. into the pressure cooker, steam for 30 minutes, then mash them into powder. Mix well in the ratio of 1 part bone shavings to 3 parts river sand to make flower base fertilizer. Place it on the bottom of the flowerpot 3 cm with a layer of soil, and then plant the flowers.

2. Nitrogen and phosphorus compound fertilizer. Take 0.5 kg of ammonium bicarbonate and 0.15 kg of potassium chloride. Zinc sulfate 0.025 kg, human excrement 2.5 kg, cow excrement 1 kg (or pig excrement 5 kg), red stone bone powder 20 kg, divided into 5 equal parts, and then spread a layer of red stone bone powder (4 Kg), sprinkle other fertilizers on it, pat it tightly with a wooden board, and then close it with straw or a film cover. After 20-25 days, it will become a nitrogen and phosphorus compound fertilizer.

3. Ammonium phosphate humate. Take 1 kilogram of decomposed biogas residue, add 0.05 kilograms of phosphate rock powder, mix and mix well and pile into a pile, paste a 3-5 cm thick layer of thin mud mixed with cow dung, and then sprinkle with a layer of fine soil, and seal for 40 days It is made into humic acid phosphate fertilizer. Then turn the humic acid phosphate fertilizer into a fine pile, re-pile and paste with thin mud, and then make holes in the pile around the top of the pile, and then pour ammonia water at the ratio of 1 kg of humic acid phosphate fertilizer to 0.05 kg, and use mud The hole is tight. After 8-10 days, it succeeds when there is no smell outside the cave. This compound fertilizer is used as a base fertilizer, and the effect is obvious.

In the above simple npk fertilizer manufacturing process, there is no fertilizer production equipment.

Single fertilizers include nitrogen fertilizer, potassium fertilizer, and phosphorus fertilizer. In fertilizers, fertilizers containing two or more components of N, P, K, and other elements are called compound fertilizers, abbreviated as compound fertilizers. A binary compound fertilizer contains two main nutrients, a ternary compound fertilizer contains three main nutrients, and a multiple compound fertilizer contains three or more nutrients.

The advantages of compound fertilizers include high active ingredients and a variety of nutrients; Less side components and minimal adverse effects on soil; Low production cost; Good physical properties. In modern agriculture, different types of compound fertilizers have been produced for graduate students based on the characteristics of different crops. Whether it is fruits and vegetables, grain crops, or trees, compound fertilizers have become one of the unavailable fertilizers.

Compound fertilizer granulator is a molding machine that can manufacture materials into specific shapes. Compound fertilizer granulator is one of the key equipment in the compound fertilizer industry, suitable for cold and hot granulation, as well as large-scale production of high, medium and low concentration compound fertilizers. The main working method is wet granulation of pellets. By using a certain amount of water or steam, the basic fertilizer is humidified in the cylinder and undergoes a thorough chemical reaction. Under certain liquid phase conditions, with the help of the rotational motion of the cylinder, the material particles are squeezed and agglomerated into balls.

This machine has the characteristics of high ball forming strength, good appearance quality, corrosion resistance, wear resistance, low energy consumption, long service life, and convenient operation and maintenance.

The use and maintenance of common compound fertilizer granulators in organic fertilizer granulator equipment:

1. Pay attention to the normal operation of various parts of the machine, check the wear level of easily worn parts, and always pay attention to replacing worn parts.

2. The bottom frame plane of the movable device should be cleaned of dust and other objects to prevent the movable bearing from moving on the bottom frame when the machine encounters materials that cannot be broken, resulting in serious accidents.

3. If the bearing oil temperature rises, it should be stopped immediately to check the cause and eliminate it.

4. If there is any impact sound during the operation of the rotating gear, it should be immediately stopped for inspection and eliminated.

In the rural pig industry, environmental inspections are becoming more and more stringent. Many pig farms have installed pig manure treatment equipment. After the pig manure is separated from solid and liquid, the dry manure must undergo aerobic composting to sell at a good price. In order to reduce the cost of composting, the fermentation time of composting should be shortened as much as possible. In the process of aerobic fermentation in farms, the choice of filler is very important.

The filler can provide carbon source, increase the porosity of the stack, and adjust the moisture content of the material. Fresh pig manure has high water content, is easy to agglomerate, and has less free space, which is not conducive to aeration and oxygen supply. Therefore, it is easy to make fermentation in an anaerobic state and produce odor, which cannot achieve the purpose of aerobic digestion. Simple pig manure has relatively few carbon sources, which is not conducive to the growth and reproduction of microorganisms. The moisture of fresh pig manure is generally 70-80%. For composting, the humidity is too high and must be adjusted. In the fertilizer production process, pig manure is a commonly used organic fertilizer raw material. However, the process of fertilizer production has certain requirements for moisture.

 In rural areas, there is a large amount of unused corn stover, which can be used as a filler for pig manure fermentation. In addition, wood chips, sawdust, and rice husk are also ideal conditioners. In the United States in recent years, many composting plants have used waste paper as a filler. Like corn stover, furfural residue and mushroom residue are also common solid wastes, which are produced in a large amount and easily cause environmental pollution. If they can be used reasonably in high-temperature composting, waste can be turned into treasure.

In addition, in order to reduce the production cost of organic fertilizer produced by pig farms, especially the use of deep tank fermentation to produce organic fertilizer, the compost composting time is often shortened in production, so corn stalks or other fillers cannot be added too much to the extent that carbon The source is too high.

Pig manure fermented composting is just that organic fertilizer granulator is generally used for fertilizer granulation. The organic fertilizer granulator has a high granulation rate, complete models, and can also be customized.

The extrusion granulation method requires less equipment for double roll granulation machines, resulting in a relatively low project investment. The scientific research conducted by the International Fertilizer Development Center (NFDC) in developed countries in 1987 showed that the annual yield of 12 × The project investment for 104t granular N, P, and K fertilizer equipment is only 50% of slurry granulation or chemical granulation, which is 20% less than steam granulation; Squeezing granulation does not require heating and humidification of raw materials, saving project investment and energy consumption. It can incorporate granulation with heat-sensitive raw materials such as potassium nitrate and some organic compounds as seasoning; No sewage or exhaust emissions during the production process, making it less prone to environmental pollution; The extrusion granulation production process is short and the actual operation is simple, which is conducive to completing the automation of production machinery and improving productivity; There are no special regulations on the characteristics and particle size analysis of the raw materials, so the raw materials come from a wider range and are more convenient for production and manufacturing. If the product promotion plan needs to be changed, it is more convenient and beneficial for small-scale and large-scale production of organic compound fertilizers; The particle size analysis of the product is uniform, with high strength, and it is not easy to cause concrete segregation or agglomeration.

The appearance design of the extrusion granulator is not as smooth as traditional methods such as disc granulator and slurry granulator for producing fertilizer pellets; It is highly likely to cause smoke and dust during the entire transportation process. But if a special process is added in the steps and the surface of the product is hard bottomed, improvement can be achieved. In addition, if chemical changes occur again between the seasoning components within the product particles, it is highly likely to cause particle fragmentation.

The roll extrusion granulation method is the entire granulation process that uses working pressure to immediately squeeze raw materials into finished products, especially when integrating into the granulation of thermistor raw materials. There are generally two types of extrusion machinery equipment: one is an elbow type granulator; Another type is a rotary roller extrusion granulator. The two types also have various forms due to their different structures. The water content in the feed of the elbow type extrusion granulator is generally 5% to 8%. After extrusion, cylindrical materials are obtained, and compound fertilizer products with a water content below 5% are obtained through refrigeration. The water content in the feed of the gelatinous rotary roller extrusion granulator can be lower, with overseas reports ranging from 0.5% to 1.5%. The strip shaped raw materials obtained through extrusion are crushed by the crusher, and small or angular compound fertilizer products are selected through two layers of screening. The crushed ultrafine powder is returned to the extruder for granulation and return, and the coarse blocks are then returned to the crusher for crushing. Because the moisture content of the product is low, there is no need to carry out drying.

The roller extrusion granulator has a wide range of applications and can granulate a variety of raw materials. Therefore, it is also known as the ammonium sulfate composite fertilizer dry extrusion granulator, two-layer roller extrusion granulator, potassium magnesium fertilizer double roller extrusion granulator, calcium chloride roller extrusion granulator, dry ammonium sulfate roller granulator, compound fertilizer roller granulator, ammonium sulfate granulator, and compound fertilizer extrusion granulator.
