The organic fertilizer production line is an equipment for mass production of bio organic fertilizers, which plays a very important role in the development of agriculture. The organic fertilizer equipment ferments crop waste and livestock waste, such as straw, corn cob, distiller’s grains, chicken manure, pig manure, and other manure containing organic substances, to produce organic fertilizer containing a large number of microbial strains. The microbial strains in the finished organic fertilizer can improve the soil structure, increase the content of organic matter in the soil, and use chemical fertilizers and compound fertilizers to greatly increase crop yield. After a certain process flow of fertilizer production line, high-quality organic fertilizer can be processed. Below is a complete set of production process flow of organic fertilizer production line:

1. First of all, mix chicken manure with a certain amount of straw powder, the amount of which depends on the water content of chicken manure. Generally, 45% of the water content is required for fermentation, that is, knead the chicken manure into a ball by hand, see the water through the fingers, but do not drip water, and release it to disperse.
2. Then add the mixture into the blender for mixing. The mixture must be even, transparent and free of lumps.
3. The raw materials are put into the fermentation trough to add the fermentation bacteria. The fermentation trough is built into a long strip of 2.5m wide and 0.8m-1m high, which is tossed once every 2 days by the compost windrow turner (the length, width and height of the fermentation trough can be determined according to the actual site). The main purpose of the fermentation is to quickly heat up, ferment, deodorize and kill harmful bacteria. Heaped for 2 days, odorless for 4 days, loose for 7 days, fragrant for 9 days and fat for 10 days. Specifically, on the second day of composting, the temperature can reach 60 ℃ – 80 ℃ (different temperature changes in different seasons), killing E.coli, insect eggs and other pests; on the fourth day, the odor of chicken manure is eliminated; on the seventh day, the compost becomes loose and dry, full of white hyphae; on the ninth day, a kind of distiller’s yeast fragrance is emitted; on the tenth day, the compost is fermented and matured.
4. The semi wet material crusher is used for crushing.
5. Then the impurities are screened out by the screening machine, and the powdered organic fertilizer is ready.
6. It can be stored by automatic packing scale.

The Organic fertilizer agitating tooth granulator is a forming machine that can make materials into a specific shape. The wet agitating tooth granulator uses the high-speed rotating mechanical mixing force and the resulting aerodynamic force to enable the continuous mixing, granulation, spheroidization, densification and other processes of fine powder materials in the machine, so as to achieve the purpose of granulation. This granulation method has a high ball forming rate, beautiful particles, and also saves energy, which is efficient and energy-saving.

Granulated finished product: The particle shape is spherical, with a sphericity of ≥ 0, 7, and a particle size generally between 0, 3, and 3 millimeters. The particle formation rate is ≥ 90%. The size of the particle diameter can be adjusted appropriately by the material mixing amount and the spindle speed. Generally, the lower the mixing amount, the higher the rotation speed, and the smaller the particle, and vice versa.

The Organic fertilizer mixing tooth granulator uses the high-speed rotating mechanical mixing force and the resulting aerodynamic force to enable the continuous mixing, granulation, spheroidization, compaction and other processes of fine powder materials in the machine, so as to achieve the purpose of granulation. The particle shape is spherical, with a sphericity of ≥ 0.7, a particle size generally between 0.3 and 5 millimeters, and a particle formation rate of ≥ 93%. The size of the particle diameter can be adjusted appropriately by the material mixing amount and the spindle speed. Generally, the lower the mixing amount, the higher the rotation speed, and the smaller the particle, and vice versa.

Which materials are suitable for Organic fertilizer agitator granulator?

The Organic fertilizer churn granulator is applicable to a wide range of materials, such as animal manure, manure, compost, green manure, sea manure, cake fertilizer, peat, and soil. Especially suitable for granulation of lightweight fine powder materials. The finer the basic particles of fine powder materials, the higher the sphericity of the particles, and the better the ball forming quality. Typical application materials include straw carbon, sludge, cow, sheep, chicken, and pig manure fermentation, straw fermentation, drug residue fermentation, residue from mushroom cultivation, and household waste fermentation.

The configuration of the organic fertilizer production line is high or low. The configuration of the organic fertilizer production line with an annual output of 50000 tons is roughly as follows:
Step 1: organic fertilizer fermentation
The fermentation of organic fertilizer collects the excrement, mixes with hay and rotten silage to make compost and ferment it. In the process of fermentation, the compost windrow turner is used to fully ferment the feces and make aerobic composting. It is a method to make the organic fertilizer stable, harmless and then turn into high-quality fertilizer by using the compost windrow turner and fermentation bacteria under aerobic conditions
Step 2: crushing and mixing of ingredients
The composted materials, such as N, P, K and other inorganic fertilizers, and other additives are crushed, proportioned and mixed in a certain proportion through the material grinder and horizontal mixer by using the batching bin.
Step 3: Granulation
A new type of organic fertilizer granulator is used to granulate materials.
Step 4: screening and return system
There is a certain difference in the particle size of the particles output from the pelletizing and molding system, which requires screening and grading. The selected roller screen is used to screen the particles.

The investment price of organic fertilizer production equipment can be more or less. If we want to produce powdered organic fertilizer processing, we only need to invest in one fermentation equipment, crusher and screening machine. The investment is 60000 yuan. If we want to produce granular organic fertilizer, we need to add organic fertilizer granulator, dryer, annual output of 10000 tons of organic fertilizer generally do not need cooling machine. About 200000 yuan has been invested. The plant site can be large or small. Generally, the total site needs 3 to 5 mu of land.

The annual output of 2000-5000 tons of small-scale organic fertilizer machine production process needs about 100000 yuan, including organic fertilizer compost windrow turner, crusher, mixer, organic fertilizer granulator, screening machine, conveyor complete equipment. The traditional fertilizer granulation production process, such as disk granulation or drum granulation, requires a dryer, cooler and other complete equipment at a price ranging from 200000 to 300000. The pig manure organic fertilizer production process covers a small area, saves money, labor and has a good effect, which is the best choice for many initial small investment.

Production process of pig manure organic fertilizer:
The production of organic fertilizer by pig manure fermentation needs good (consumption) oxygen fermentation. Therefore, in the process of operation, oxygen supply measures should be increased to make sure that it is well mixed, turned over frequently and aerated. Otherwise, it will cause anaerobic fermentation and produce odor, which will affect the effect of fertilizer. Fermentation complete. Generally, 48 hours after the pig manure is piled up, the temperature rises to 50-60 ℃, and on the third day, it can reach above 65 ℃. In this high temperature, it can be turned over once by the fermentation compost windrow turner of Zhengzhou Huaqiang Heavy Industry generally, there will be two times of high temperature above 65 ℃ in the fermentation process. Turning over twice can complete the fermentation, which can be completed in a normal week or so. The material was dark brown, and the temperature began to drop to normal temperature, indicating that the fermentation was completed.
Industry development drives the improvement of economic level, which is the law of market development and an inevitable result. As an important pillar of the agricultural machinery industry, organic fertilizer equipment has always been ahead of the industry. In recent years, it has reached a higher technical level with the support of high-tech. In fact, through analysis, it can be found that the development of the agricultural industry is closely related to the organic fertilizer equipment industry. Through the promotion of organic fertilizers by the Ministry of Rural Agriculture, everyone has also understood that organic fertilizers are necessary for planting green organic food. Understanding this relationship, some friends have seen business opportunities and have invested in the organic fertilizer processing industry. However, when purchasing organic fertilizer equipment, they found that the prices of organic fertilizer equipment are diversified, ranging from within 100000 to millions of organic fertilizer production lines.

The birth of the straw production line of Organic fertilizer can solve the problem of straw burning innocuously. This equipment can quickly and innocuously solve agricultural wastes such as straw, wheat straw, corn stalk and other crop straws that are randomly abandoned in the field and rotted and smelly or burned in the open air, completely kill diseases, pests and weeds in agricultural wastes, and quickly convert them into excellent Organic fertilizer.

Technological process of straw Organic fertilizer production line:

1. Ingredients: Various animal excrement such as chicken manure, pig manure, cow manure, biogas residue, or raw materials that can be fermented or have fertilizer effects after treatment shall be prepared in a certain proportion (based on market demand and soil testing results in different regions).

2. Mixing of raw materials: Mix the prepared raw materials evenly to improve the overall uniformity of the fertilizer particles.

3. Raw material granulation: The evenly stirred raw material is fed into a Organic fertilizer granulator for granulation (either a drum granulator or an extrusion granulator can be used).

4. Particle drying: The particles made by the granulator are fed into the dryer to dry the moisture contained in the particles, increasing their strength and facilitating storage.

5. Particle cooling: The dried fertilizer particles have a high temperature and are prone to clumping. After cooling, they are easy to pack, store, and transport.

6. Particle grading: Grading the cooled particles, crushing and re granulating the unqualified particles, and screening out the qualified products.

7. Finished film: Coating qualified products to increase the brightness and roundness of particles.

8. Finished product packaging: Bag the coated particles, also known as finished products, and store them in a ventilated place.

The new Organic fertilizer production line uses a unique process of three in one machine to complete the whole process of low-temperature drying, cooling and screening at one time, with less equipment investment and low operating costs. The survival rate of microorganisms is>90%. Organic fertilizer production equipment is widely used in animal husbandry, large, small and medium-sized breeding plants, feed plants, and organic waste re granulation in brewing, sugar making, paper making, medicine, tobacco factories and other industries, and is the ideal equipment preferred by biological Organic fertilizer production enterprises.

The production line of chicken manure organic fertilizer is a complete set of production equipment which uses fresh chicken manure as raw material and processes a series of organic fertilizer machine to produce natural organic chicken manure fertilizer. The production and processing of chicken manure organic fertilizer need two steps: the early fermentation and treatment part and the deep processing granulation part. The supporting equipment of chicken manure organic fertilizer needs fermentation compost windrow turner, organic fertilizer crusher, roller screen machine, horizontal mixer, organic fertilizer granulator, rotary dryer, cooler, screen machine, coating machine, packaging machine, conveyor and other equipment.

In the chicken manure organic fertilizer production line, fresh chicken manure with water content of 65% – 85% and a certain amount of auxiliary materials (dry straw, broken grass, dry chicken manure, etc.) are placed in the fermentation pile, and at the same time, the fermentation equipment (compost windrow turner) is used for full mixing; the compost windrow turner is continuously pushed to adjust the water, carbon and nitrogen ratio (C / N); the mixed fresh chicken manure is fermented for 7 days under the appropriate temperature and oxygen conditions; then it is fed into the organic manure In the fertilizer dryer, the chicken manure block is in full contact with the hot air and quickly loses the surface moisture; because the dryer is equipped with high-speed rotating crushing equipment, the chicken manure block is constantly broken and dehydrated to complete the drying process; the organic fertilizer granulator is used for granulation; the dryer evaporates the moisture in the particles; the cooler quickly reduces the particle temperature; the screening machine selects the unqualified particles Re crushing and granulation; coating of qualified particles; quantitative packaging of final organic fertilizer products. 

It is a win-win way to process livestock manure into organic fertilizer, which can not only meet the requirements of environmental protection, but also achieve the value-added income. The problem of livestock manure pollution has aroused strong concern of the society. Under the pressure of environmental protection, more and more farms begin to solve it, trying to change the current passive situation.
It has been proved that organic fertilizer can be produced by using animal manure. It is an effective harmless treatment and resource utilization way for large-scale pig farm. According to the requirements of customers, we can design 10000-200000 tons of pig manure organic fertilizer production line and workshop design, and provide a complete set of pig manure organic fertilizer machine.
Pig manure organic fertilizer products can be made into granules or powders, which depends on market demand. In order to balance nutrients and be suitable for transportation and storage, it is suggested that pig manure organic fertilizer should be made into granular products with cylindrical and spherical shape.

Pig manure organic fertilizer production line is a series of production equipment which uses pig manure as raw material, ferments and processes with high-tech equipment to produce organic fertilizer.
There are two steps for pig manure to process commercial organic fertilizer: the first step is fermentation and treatment, and the second step is granulation. The pre-treatment part is also called powder organic fertilizer processing equipment, which includes fermentation compost windrow turner, organic fertilizer grinder, roller screen and other equipment. The pelletizing production part includes: mixing mixer, organic fertilizer granulator, rotary dryer, cooler, roller screen, coating machine, automatic weighing and packaging machine. Through the organic fertilizer production line, the manure of livestock and poultry, straw and rice husk, biogas sludge, kitchen waste and urban waste are processed into organic fertilizer, which can not only reduce environmental pollution but also turn waste into treasure.

In order to ensure that we all have clean domestic water, almost every city has a sewage treatment plant. However, the domestic sludge generated by sewage treatment plants has always been a headache for environmental protection departments, as these sludge are rich in a large amount of organic matter and pathogenic bacteria, insect eggs, weed species, and heavy metal ions, which are prone to producing foul odor, breeding mosquitoes and flies, and polluting the environment. At present, three treatment methods are mainly used, namely, landfill, reclamation and incineration. The existing treatment methods are very easy to cause secondary environmental pollution and waste a lot of Organic fertilizer resources. After microbial fermentation treatment, domestic sludge can be turned into biological Organic fertilizer material, which is suitable for trees, flowers, lawns and used as the substrate for tree container seedling raising. Good growth effects have been obtained, and the physical, chemical and biological properties of soil have been improved. Thus, the resource utilization of domestic sludge has been completely realized.

The municipal sludge Organic fertilizer production line has good automatic and continuous operation, simple process structure, less equipment, and greatly reduces investment. The automation level of the process has been greatly improved by using metal thermometers for temperature measurement, electromagnetic speed regulating motors, rotary level sensors, and electronic continuous measurement sensors.

Introduction to the production line process of urban sludge Organic fertilizer material:

1. Transfer dehydrated sludge with a moisture content of about 40% (suitable viscosity) to a disc homogenizer, and add evenly mixed materials to the rotating disc of the disc granulator through uninterrupted rotation of the disc.

2. Transport to an efficient dryer and complete the preliminary drying of the fertilizer at high temperatures after treatment with a jet induced draft fan. After drying, the moisture content is controlled at 10% to 15%.

3. It is delivered to the Organic fertilizer material screening machine. The special design of the screening machine can completely solve the problem of screen adhesion.

4. The qualified particles after screening are sent to the metering silo, and the large particles are sent to the metering silo after being crushed by the Organic fertilizer material grinder to meet the requirements.

5. Qualified raw materials such as nitrogen, phosphorus, potassium, and fillers are transported to their respective measuring silos.

6. The weighed raw materials are transported to the drum granulator, and saturated steam (or water) is introduced. The materials form a rolling bed with the friction generated during the rotation of the drum granulator. The squeezing force generated by the rolling causes the materials containing a certain liquid phase to aggregate into small particles, which become the core and adhere to the surrounding powder to form qualified particles.

7. It is delivered to the Organic fertilizer material dryer for heat exchange with the heat from the hot blast stove.

8. Transported to the hot screening for particle separation, fine particles are directly returned to the drum granulator as the core and continue to participate in particle adhesion and balling.

9. The screened semi-finished particles are sent to the Organic fertilizer cooler, and the fertilizer is cooled by natural or forced cold air.

10. Transported to the finished product screening machine, the large particles are crushed by the crusher and returned to the drum granulator to continue participating in balling.

11. The qualified products after screening are transported to the coating machine for coating treatment.

12. Transport to a fully automatic packaging scale for weighing, packaging, and warehousing.

13. Drying, cooling, and workshop dust are discharged after three stages of treatment: cyclone dust collector, labyrinth dust chamber, and wet washing.

The manure of the farm is piled up everywhere and the sewage is discharged at will, which not only pollutes the surrounding environment, but also directly affects the health and epidemic prevention of the farm itself, reduces the quality of livestock products, and causes the occurrence and spread of some diseases. According to the obvious decline of organic matter in agricultural cultivated land, a large number of organic fertilizers are urgently needed to improve the soil. On the other hand, a large number of livestock and poultry manure produced by large-scale breeding can not be effectively used, which not only wastes resources, but also pollutes the environment, bringing adverse effects on the surrounding environment and residents’ lives.

The research and development of fertilizer production process will be conducive to promoting the formation of the industrial chain of harmless treatment, resource utilization and commercialized management of livestock and poultry manure, achieving the goal of industrialization, marketization and large-scale production, and effectively promoting the development of ecological agriculture and circular economy. The resource utilization of livestock and poultry waste is included in the “No.1 Project”. Focusing on large-scale animal husbandry counties and large-scale farms, with agricultural organic fertilizer and rural energy as the main utilization direction, ensure that the comprehensive utilization rate of livestock and poultry manure is more than 75%, the equipment matching rate of manure treatment facilities and equipment of large-scale farms is more than 95%, and the equipment matching rate of manure treatment facilities and equipment of large-scale farms is 100%.

The fertilizer equipment of the organic fertilizer production process mainly consists of fermentation equipment, drying equipment, deodorization and dust removal system, grinding equipment, batching system, mixing equipment, organic fertilizer granulator and finished product packaging equipment. Fermentation equipment includes: feed conveyor, biological deodorizer, mixer, special throwing machine, oxygen supply system and automatic control system.  

The organic fertilizer machinery of Zhengzhou Huaqiang Machinery Ltd has been greatly improved in terms of environmental protection, capacity and reliability of equipment. Why the purchase of organic fertilizer machine should be customized? This is a reasonable and appropriate choice for the project investor. How to determine the quality reliability of the customized organic fertilizer machine?
On the one hand, the better choice to develop the organic fertilizer production line is to customize the equipment. The reasons for choosing organic fertilizer equipment to be customized are as follows: in terms of work efficiency, customized processing can improve the work efficiency of workers. In terms of equipment quality coordination, customized coordination is better. In terms of equipment area, the customized organic fertilizer equipment occupies more reasonable space and does not waste space.

1. The customized organic fertilizer machine improves the working efficiency of workers. The customized equipment takes the workers’ vision into full consideration from the production process layout. The distance to be moved when working on the production line can effectively reduce the moving time of workers between different equipment, so as to improve the efficiency. From the perspective of workers’ vision, the working position can effectively observe the situation of the section in charge of it, and also improve the efficiency of workers.
2. In terms of coordination in the work of organic fertilizer equipment, Zhengzhou Tianci Heavy Industry Machinery Ltd believes that the customized organic fertilizer machine is more coordinated. Customized equipment, fully considering the suitability of various aspects of process and raw materials, as well as conveying and feeding and main equipment. Let each equipment according to the established production capacity, not fast or slow, moderate production, so as not to cause production congestion.
3. In terms of the floor area of the organic fertilizer processing equipment, the space utilization rate is higher. From project approval to equipment inspection and process finalization of organic fertilizer processing project, organic fertilizer equipment manufacturers will comprehensively design equipment size and transportation distance according to site area, shape, raw material quantity, planned output, and design reasonable process equipment layout through calculation. So as to increase the occupation of working area by equipment.
