We all know that the fertilizer industry has brought us great economic development, but at the same time, it will also have a negative impact on us, which is environmental pollution, which is the so-called double-edged sword. However, the current organic fertilizer equipment industry has been changing this situation and making efforts to minimize pollution. Thus, there are improved organic fertilizer equipment that can reduce our burden a bit, and organic fertilizer equipment that can contribute to us. It is so reassuring that there is no need to worry about environmental pollution. However, relying solely on this equipment cannot play a decisive role, and it still depends on our collective efforts and collective solutions.

Process flow of powdered organic fertilizer production line:

The production process of powdered organic fertilizer equipment mainly includes fermentation, crushing, screening, and packaging. The production equipment used is organic fertilizer tipping machine, forklift silo, organic fertilizer crusher, organic fertilizer screening machine, organic fertilizer automatic packaging machine, organic fertilizer belt conveyor, etc.

When producing powdery organic fertilizer fermentation, it is generally used to use strip pile fermentation or fermentation tank fermentation. Strip pile fermentation is the process of stacking raw materials into 2.5 meter wide, 1.2 meter high, and 50 meter long strip piles on an open field, and then using a tracked tipping machine for anti fermentation. A fermentation tank is usually built with a width of 4 meters, a height of 1.5 meters, and a length of 100 meters. The tank type tipping machine is used for pile fermentation.

1. Ingredients before fermentation: When the moisture content of the raw material is too low, water or animal urine should be added to increase the moisture content. When the water content of raw materials is too high, solid-liquid separation or the addition of auxiliary materials should be adopted to reduce the water content. Auxiliary materials can be plant residues such as straw, peanut shells, etc. It is advisable to adjust the water content to around 55%.

2. After the raw materials are properly proportioned, they should be piled up into strips or placed in a fermentation tank, sprinkled with fermentation bacteria, and then stirred evenly using a flipping device. Wait for the temperature to rise and ferment. When the temperature rises to 70 degrees, the flipping machine should be immediately used for flipping, temperature control, and oxygen blowing. The temperature should be observed at any time, and the raw materials should be flipped and treated in a timely manner until they start to cool down, which can reduce the frequency of flipping. Until the raw materials are completely fermented and decomposed.

3. Raw material crushing: In order to avoid agglomeration during storage, fermented and decomposed raw materials are also finely crushed using a dedicated organic fertilizer crusher. After the first crushing, the raw materials need to be sieved once, and the incompletely crushed materials are sieved out for secondary crushing, ultimately obtaining a uniform and fine organic fertilizer.

4. At this point, the production process of powdered organic fertilizer equipment is completed and can be packaged and sold.

The fermentation of organic fertilizer production line mainly realizes the degradation and transformation of organic fertilizer, which requires a series of processes. A large amount of oxygen is needed in the conversion process. How does the organic fertilizer production line solve the oxygen problem? Today, Zhengzhou Tianci Heavy Industry will explain how to solve the oxygen problem in the organic fertilizer production line.

Trough type aerobic fermentation process is an organic fertilizer aerobic fermentation process. The principle of high-temperature aerobic rapid composting technology is actually a process of microbial decomposition of organic materials. In this process, organic materials become small molecule yellow humic acid under the decomposition of microorganisms, decompose unusable nutrients into available nitrogen, phosphorus and potassium, and convert macromolecular protein into small fraction The degradation of organic materials is a process of organic matter transformation.

The equipment of the organic fertilizer production line is actually an environmentally friendly product, and the raw materials used for organic fertilizer are also sourced from local organic waste. The raw materials include crop straw, farm manure, humic acid, furfural residue, vegetable waste, orchard waste branches, soybean meal, and other raw materials. These agricultural and aquaculture waste can be processed by organic fertilizer production equipment to produce organic fertilizers that are beneficial to our fields, This solution not only allows local materials to be sourced, but also saves costs for enterprises, and effectively helps local relevant departments alleviate environmental pressure. I believe everyone is familiar with the nutritional components contained in organic fertilizers, which have strong fertilizer effects and can effectively alleviate a series of situations such as soil compaction and the dissipation of soil microbial communities. Long term application of organic fertilizers is a necessary measure to maintain a virtuous cycle of agricultural ecology in China.

In today’s society, with the increasing demand of consumers for intelligent production of organic fertilizer granulator, the multifunctional organic fertilizer equipment will receive more attention and love from customers.
Facing the huge market population, the demand for organic fertilizer granulator will naturally increase. In order to better serve customers and consumers, the organic fertilizer granulator manufacturers only think about the direction of intelligence and automation, in order to better improve the production technology of organic fertilizer production equipment. Therefore, in order to make the organic fertilizer equipment better serve customers, the enterprise only needs to carry out technological innovation on the equipment as soon as possible, so that the development of the equipment is closer to the production, so that the organic fertilizer machine will develop more healthily. Only with the continuous upgrading and rapid growth of organic fertilizer machinery, can we better promote the development of enterprise economy.

So far, almost 80% of the organic fertilizer machines have completed the progress of agricultural circular development. As we know, biogas is recyclable. This development model has played an environmental protection role, effectively prevent pollution, improve the utilization rate of waste, can be said to turn waste into treasure, now the organic fertilizer granulator has also realized the function of green environmental protection.
Organic fertilizer machine is actually to convert animal manure fertilizer into organic fertilizer, in which some crop straw can be added into animal manure. Now with the continuous improvement of technology, the technical level of organic fertilizer granulator manufacturers and organic fertilizer equipment has also reached a new level. Now, the power of organic fertilizer equipment manufacturers is growing. 

1. Fermentation
The raw materials are collected and mixed with straw and chicken manure to make compost and ferment. In the process of fermentation and seed production, the use of a compost windrow turner can make the material fully ferment. Only by turning the pile in time and evenly can this be achieved. Some places are very dry, some places are very wet, which will affect the fermentation quality, so it is recommended to use a stacker.
2. Crushing and mixing of ingredients
The composted materials, inorganic fertilizers such as N, P, K and other additives are crushed, proportioned and mixed through a material crusher and a horizontal mixer in a certain proportion. The function of this system is to crush, mix and mix the composted materials, nitrogen, phosphorus, potassium, inorganic fertilizers and other additives in a certain proportion. According to many years of experience, the following suggestions are put forward for the equipment: the vertical crusher is used to crush the compost of cow manure, which is not easy to stick to the wall and block; the multi-layer turbulent chain hammer structure is used to improve the crushing performance; the continuous automatic batching system is suitable for the dynamic measurement and batching control of organic fertilizer raw materials; the mixing industry is equipped with a double shaft continuous mixer, which has good sealing performance, and the sticky and wet materials are not easy to be at the root of the mixing shaft adhere.

3. Granulation
A new type of organic fertilizer granulator was used to granulate the materials. The function of this system is to make particles from the materials which have been mixed completely. The advantages of the granulator are: wide adaptability of raw materials, wide requirements for raw material density and moisture content of raw materials, stable granulation, high forming rate of granules, uniform appearance of finished products, and no easy breakage;
Important steps in the production process of chicken manure organic fertilizer granulation.
4. Drying
Using the dryer, the granulated particles can be further removed to meet the standard requirements of moisture content of organic fertilizer.
5. Cooling
Cooling the granular materials with a cooler helps to store the particles with good quality. The hot particles from the dryer enter into the counter flow cooler from the top. The dry air enters from the lower part of the cooler under the action of the cooling fan, and carries out full cold and heat exchange with the hot and humid particles under the upper part. After cooling, the difference between particle temperature and ambient temperature is less than 5 ℃.
6. Screening
The unqualified particles are separated by drum screening machine, and transported to the crusher by belt conveyor, and then crushed and stirred for granulation again. The qualified particles are carried out in the next process.
7. Packaging
The qualified granules are packed by automatic quantitative packaging machine.
The whole organic fertilizer production process is connected by belt conveyor, bucket elevator or screw conveyor to realize the automatic production of organic fertilizer. The whole set of equipment only needs two or three workers to operate. 

The drum dryer is one of the important equipment in the compound fertilizer production line. The main function of the drum dryer is to remove excess moisture from the raw materials. The entire equipment is installed on a horizontal plane, with the feeding and discharging ends forming an inclined angle. By rotating the internal lifting plate, the material is transported from one end to the other end. The internal lifting plate evenly sprays the material inside the dryer, making it better in contact with hot air, Accelerate the evaporation of water.

The processed organic fertilizer particles to be dried are transported by a belt conveyor to the feed inlet of the feeder, and the particle material flows into the drum dryer barrel along the feeder chute. The feeder is embedded on the outer side of the drying cylinder. As the deceleration drive system drives the overall rotation, the granular material moves backwards with the rotation of the drying cylinder, and the feeder end is filled with heated hot air. Directly contact the material in the drying cylinder to evaporate its water vapor and dry it. During the drying process, the deceleration drive system is adjusted by a frequency converter to adjust the speed of rotation based on the degree of material drying. The material is dried dry, accelerating the value of the frequency converter to quickly pass through the integrated device of drying, cooling, and screening. If the drying effect is not good, lower the value of the frequency converter to make the drying, cooling, and screening integrated device rotate slowly, and the material stays inside for a longer time. The middle induced draft hood draws the dried water vapor out of the drying cylinder. Then, the dried material enters the cooling drum as it rotates. Under the action of the middle induced draft hood, natural air enters the cooling drum from the unclosed end of the cooling machine. As the cooling drum rotates, it picks up the material and directly lowers the temperature of the material to the natural temperature. Afterwards, the granular materials enter the drum screen, and the unqualified materials are screened out from the drum screen. The qualified materials directly enter the next packaging section.

The heat source of the dryer can be coal, electricity, natural gas, biomass particles, biomass oil, etc. The use cost of coal is lower, and the use cost of electricity is higher.

The current drum dryer is well made and has mature manufacturing technology. It not only has high output and lower energy consumption, but also uses high-temperature air generated by a hot air stove to evenly dry materials and is equipped with dust removal technology, which can better meet environmental requirements.

Adding non-toxic and harmless sawdust or coarse rice bran and other auxiliary materials (accounting for 10% – 15% of the total amount of fermented pig manure) in fresh pig manure, or try to mix chicken manure to regulate water content, ventilation and carbon nitrogen ratio, so as to control the water content of pig manure at about 60%. The C / N ratio is between 30 and 40.

The second is to add superphosphate, which accounts for 5% of the total fermentation material, to adjust the pH of pig manure to about 7.5. The additives must be mixed evenly with pig manure, stirred by organic fertilizer machine, and then stacked in a ladder shape in the pretreatment plant. The stacking trapezoid is 2m in width at the top and 3M in the bottom. The stacking strip is in the same direction as the gradient of the ground, so that the exudate can flow into the small ditch on the low side. The stacking time in the pretreatment plant was 7 days in summer and autumn, 10 days in winter and spring, and then it was fermented in fermentation trough.

The pretreatment process of pig manure organic fertilizer production process is as follows: fresh pig manure – adding fermentation bacteria – adding sawdust, rice bran, chicken manure – adding calcium superphosphate – uniform mixing – trapezoidal stacking for 7-10 days – sent to the fermentation workshop 

The conditions for pig manure fermentation and fermentation products

1. There should be some suitable microorganism.

2. To ensure or control the various conditions of microbial metabolism (medium composition, temperature, solubility, pH, etc.).

3. There should be equipment for microbial fermentation.

4. There should be methods and equipment for extracting strains or metabolites and refining them into products.

The organic fertilizer granulator machine is a key equipment for producing granular organic fertilizer. After granulation, powdered organic fertilizer can not only flexibly adjust the fertilizer formula, but also increase the price per ton by 1-2 times, making the profit of organic fertilizer greater.

Organic fertilizer granulator machines are divided into various types:

1. Agitator granulator: Utilizing the high-speed rotating mechanical stirring force and the resulting aerodynamic force, the fine powder material is continuously mixed, granulated, spheroidized, and compacted in the machine 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 ≥ 95%. 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. Suitable for various organic fertilizer raw materials such as animal manure, sludge, clay, etc. Stirring teeth granulator

2. Disc granulator: The disc granulator has a novel and reasonable structure, with reduced weight and height. The process layout is flexible and convenient, suitable for the renovation of old factories. The inclination angle of the large plate can be adjusted. Adopting angle washers for flexible and convenient adjustment. The use of a unique unpowered combination scraper integration reduces auxiliary power consumption. The large plate is composed of a plate body and a plate section. Reduce the power of the main motor. The disc section can be adjusted up and down along the disc body. The end of the disc joint is an edge flange, which ensures that the material ball is not pulled or torn when it is discharged from the disc. A brand new desilting design, consisting of a combination of unpowered scraper for edge and bottom cleaning, angle cleaning scraper for corner cleaning, and unique disc processing technology. The desilting and ball forming effects are good, without large mud balls. The diameter of the feed ball is 90% between 3-5mm.

3. Roller extrusion granulator: Produced using a non drying room temperature process, this equipment has low investment and good economic benefits. The complete set of equipment has a compact layout, scientific and reasonable design, energy conservation and consumption reduction, no discharge of three wastes, stable operation, reliable operation, and convenient maintenance. Wide adaptability of raw materials, suitable for granulation of various raw materials such as compound fertilizers, chemicals, feed, etc., with high product granulation rate. It can produce various concentrations and types of compound fertilizers (including organic fertilizers, inorganic fertilizers, biological fertilizers, magnetized fertilizers, etc.). Its advantage is that there is no need for drying treatment, and equipment investment is greatly reduced.

4. Organic fertilizer drum granulator: It 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 new generation rotary drum granulator has been developed by our company’s technical personnel, who have accumulated years of experience in the production of compound fertilizers. This machine has the advantages of high ball forming strength, corrosion resistance, wear resistance, simple operation, low energy consumption, long service life, and convenient maintenance. It is currently a relatively advanced granulation equipment in China.

Organic fertilizer is a good project for many people, but they don’t know much about this industry. Therefore, it needs to be investigated for a long time before it can be put into the production of organic fertilizer. The investment in the production of organic fertilizer can be large or small. If you only consider the treatment of livestock and poultry manure, a fermentation compost windrow turner can be used, Many small-scale organic fertilizer plants only need fermentation equipment, crusher, mixer, organic fertilizer granulator, screening machine and quantitative packaging scale to put into production. However, this mode of production requires a lot of human operation, such as the fermentation of raw materials in the early stage and the drying after granulation, which needs manual turning and drying.
The complete set of organic fertilizer plant production line only needs five or six people. It doesn’t need too much investment in human resources, but it needs to expand the investment in organic fertilizer machine. Investment in organic fertilizer is not only in equipment, but also in site and infrastructure. Therefore, the investment in organic fertilizer ranges from tens of thousands to hundreds of thousands.

The simple configuration of organic fertilizer machine includes: fermentation compost windrow turner, organic fertilizer crusher, horizontal mixer, organic fertilizer granulator, drum screening machine and quantitative packaging scale. These five equipment can make organic fertilizer put into production. If it is necessary to reduce the input of labor cost, several belt conveyors can be added. In this set of equipment, it is necessary to manually turn over the organic fertilizer fermentation and dry the organic fertilizer after granulation. This simple configuration of organic fertilizer machine is suitable for small organic fertilizer processing plants or farms. Under the premise of small equipment cost, the production of organic fertilizer can run normally.
