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.

Common processes for several compound fertilizer production lines

fertilizer granulator May 4, 2023

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.

Process Introduction and Maintenance Methods of Compound Fertilizer Granulator

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.

Why add straw to the pig manure organic fertilizer production line

fertilizer granulator Apr 26, 2023

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.

Types of humic acid fertilizer and organic fertilizer equipment

fertilizer granulator Apr 26, 2023

Humic acid fertilizer refers to the production of a large amount of humic acid, nitrogen, phosphorus, potassium and some trace elements required by crop growth and development by using different production methods of peat, lignite and weathered coal. Humic acid, as the raw material of organic fertilizer production equipment, plays an important role in agricultural production, such as stimulating crop growth, improving soil, increasing nutrients and strengthening soil microbial activities.

Varieties of humic acid fertilizer

1. Humic acid fertilizers can be divided into two categories: natural humic acid and artificial humic acid according to their sources. Among natural humic acids, they are divided into soil sodium humic acid (white) phytic acid, coal coal humic acid, Water humic acid and mold humic acid, etc. Humic acid can be made into solid particles by NPK fertilizer granulator.

2. Humic acid fertilizers can be divided into primary humic acid and regenerated humic acid (including humic acid in natural weathered coal and artificial oxidized coal) according to the production method.

3. Humic acid fertilizers can be classified into fulvic acid, brown fulvic acid and black fulvic acid according to their solubility and color in solvents. In the earlier literature, there were also names of grey fulvic acid, brown fulvic acid and green humic acid, which were actually separated from different solvents.

4. According to the natural binding state, humic acid fertilizer can be divided into free humic acid and (calcium, magnesium) combined humic acid. We provide humic acid processing equipment, disc granulator, grinder, dryer, etc.

5. Humic acid fertilizer can be divided into type A, type B (true humic acid), RP type and P type (immature humic acid) according to the humification degree of humic acid (such as absorption coefficient).

Process and working principle of a new type of organic fertilizer granulator

fertilizer granulator Apr 26, 2023

The working principle of the new organic fertilizer granulator: the new organic fertilizer granulator uses the high-speed rotating mechanical stirring force and the generated aerodynamic force to continuously realize the process of mixing, granulating, spheroidizing and densification of 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%. The particle diameter can be adjusted appropriately according to the mixing amount of the material and the spindle speed. The lower the mixing amount, the higher the rotation speed, the larger the particles Small, and vice versa. Scope of application: This machine is especially suitable for granulating light and fine powder materials. The finer the basic particles of the fine powder material, the higher the sphericity of the particles, and the better the quality of the particles. Typical application materials: chicken manure, pig manure, cow manure, charcoal, clay, kaolin, etc. In view of the particularity of organic fermented fertilizer and organic fertilizer raw materials such as livestock manure, manure, retting manure, green manure, sea manure, cake fertilizer, peat, soil miscellaneous fertilizer, three wastes, microorganisms and other municipal solid wastes, the particles are granules.

The qualified rate of granulation by this machine is as high as 80-90%, which is suitable for a variety of different formulations. The compressive strength of organic fertilizer is higher than that of discs and drums, and the ball rate is lower than 15%. The stepless speed regulation function of this machine can adjust the uniformity of particle size according to user requirements. This machine is suitable for the direct granulation of organic fertilizer after fermentation, saving drying process and greatly reducing production cost. Now this new type of organic fertilizer wet granulator is popular among users. The birth of new products, new production technology, energy saving and environmental protection are all trustworthy.

Disc granulator is suitable for granulation process of organic-inorganic compound fertilizer

fertilizer granulator Apr 26, 2023

In a complete fertilizer production line, granulation is the key process in the whole production process. The productivity of organic fertilizer granulator, the strength and shape of granule produced by the granulator directly affect the quality of the final product.

In many fertilizer production enterprises, the most used fertilizer granulation equipment are drum granulator, extrusion granulator and disc granulator. Among the three granulation methods, the disc granulator machine is more suitable for the granulation of organic-inorganic compound fertilizer, and the effect is ideal.

Disc granulator machine is mainly composed of granulation disc, spray system, transmission device, bracket and so on. During production, the powder raw materials are conveyed by the belt conveyor to the granulation disc in the disc granulator. The rotating disc with an inclination of 50° rotates the animal material. When the material is brought to a certain height, its own gravity and inertia Under the action of the force, it breaks away from the disc and slides down along the arc track to complete the rolling required for granulation. At the same time, the liquid injected by the spray system will be evenly sprayed on the rolling material to agglomerate into granules, thus completing The whole granulation process, according to the principles applied in this granulation process, we can call it agglomerate granulation process. With the continuous addition of raw materials, the manufactured particles fall across the edge of the disk under the action of centrifugal force and fall into the belt conveyor equipment below.

As a mature model, the disc granulator has experienced the test of various materials. However, any equipment has its advantages and disadvantages. In the face of different raw materials and production processes, there are also corresponding models. In the actual NPK fertilizer production line, the selection of granulation equipment suitable for materials can make the whole fertilizer production process play a maximum benefit.

What are the common treatment methods for farm manure? How to make organic fertilizer?

fertilizer granulator Apr 26, 2023

There are two common methods to deal with feces in farms
1. Drying treatment. It is the excrement dehydration to facilitate the use, mainly has the natural drying and the high temperature fast drying. Natural drying is to use sunlight to dry livestock manure; high temperature and rapid drying is to dry artificially through a dryer. The commonly used drum dryer can reduce the moisture content of chicken manure from 70% to 75% in a short period of time to less than 8%. However, there are some disadvantages such as the secondary pollution of odor discharged by the dryer and the poor fertilizer efficiency caused by too high treatment temperature.
2. Aerobic composting. Livestock manure contains a lot of organic matter and rich nutrients such as nitrogen, phosphorus, potassium and so on, which is a valuable resource for the sustainable development of agriculture. Therefore, aerobic composting of manure is widely used at present. According to the characteristics of manure raw materials and auxiliary materials, according to the carbon nitrogen ratio and moisture content required for composting, manure and auxiliary materials are mixed in a certain proportion. The fertilizer production machine properly controls the oxygen and temperature in the heap, so that the manure can be rapidly fermented to produce organic fertilizer. The advantages of this method are less odor, more dry, easy to package and apply. It can be used as soil amendment or organic fertilizer in agricultural production.

Steps of making organic fertilizer from manure 
1. Raw material ingredients: chicken manure, pig manure, cow manure, biogas residue and other animal manure or raw materials that can be fermented or have fertilizer efficiency after treatment are equipped in a certain proportion (according to market demand and local soil test results).
2. Mixing of raw materials: Stir the prepared raw materials evenly to increase the uniform fertilizer efficiency content of the overall fertilizer particles.
3. Raw material granulation: Feed the uniformly stirred raw materials into the fertilizer granulator machine for granulation (rotary granulator or extrusion granulator can be used).
4. Granule drying: The granules made by the granulator are sent to the dryer to dry the moisture contained in the granules to increase the strength of the granules and facilitate storage.
5. Granule cooling: The temperature of dried fertilizer granules is too high and easy to agglomerate. After cooling, it is convenient for bagging storage and transportation.
6. Particle classification: The cooled particles are classified, the unqualified particles are crushed and re-granulated, and the qualified products are screened out.
7. Finished film: Coating qualified products to increase the brightness and roundness of the particles.
8. Finished product packaging: Pack the coated particles, which is the finished product, in a ventilated place.

What are the benefits of producing composite fertilizers with roller extrusion granulators

fertilizer granulator Apr 23, 2023

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.
