There is an inevitable problem in various livestock industries, including pig farms, cattle farms, chicken farms, duck farms and other livestock industries, that is, fecal waste treatment. In the past two years, environmental protection has hit every breeding hard, especially for small farmers, it is simply a financial failure. Large fecal waste treatment equipment costs too much. Powdered Organic fertilizer production lines are small Manure production lines, with low investment, which can also bring good results, Not only has it solved environmental issues, but it has also expanded a broader outlet for various breeding farms.

The powdery Organic fertilizer production line is cheaper than the granular Manure production line, and requires less equipment. In addition, the process is simple. The fermentation part of the main equipment is mainly composed of a trough dumper. The trough dumper is suitable for one machine with multiple tanks. The crushing part is composed of a semi wet material pulverizer.

The powdery Organic fertilizer production lines mainly consists of tipping machine, drum screening machine, belt conveyor horizontal mixer, and pulverizer to form powdery Manure equipment. The processed materials mainly include feces, straw, and tree branches. Compared with the granular Manure production line, the powdered Manure production line has less granulation, drying, cooling and other processes. The process is simple, and the price is cheaper than the granular Manure production line. The cost can be recovered within one year.

At present, the market price of cow dung Manure is 500-600 yuan for powdered Manure; Granular Manure is 800-1200 yuan, mainly sold to areas where flowers and plants are planted, such as Hainan, Suqian and other areas. Organic vegetables are familiar to everyone. Their fertilizer is cow dung, also called cow dung Manure. Cow dung Manure is fermented by biological bacteria to remove odor. Reduce the generation of calories and achieve high fertilizer efficiency. The process involves rapid heating, deodorization, dehydration, and decay. The benefits of using cow manure as fertilizer are also good.

The production process of NPK compound fertilizer equipment mainly involves mixing organic solid waste with a moisture content of less than 60%, auxiliary materials (such as plant straw), microbial fermentation agents, etc. Evenly, and using pool type aerobic continuous fermentation to fully decompose, sterilize, deodorize, and remove water. The moisture content of the decomposed material is generally 30-35%. After screening and magnetic separation, it can be directly used for pelletizing to produce spherical Manure, or further drying to produce powdery organic fertilizer.

The NPK composite fertilizer production process consists of multiple processes: raw material measurement, raw material crushing, granulation, drying, cooling, screening, coating, and packaging. Each process has strict indicator control, and none is indispensable. Firstly, technical personnel develop corresponding fertilizer production formulas based on market needs or customer needs, combined with the market situation of raw materials, and refine them into the input amount of raw materials.

NPK Fertilizer Production Line Process Design Description:

1. Compound fertilizer ingredient process:

The operators strictly follow the technical personnel’s requirements for the amount of each raw material added, and add various raw materials such as N, P, K, and additives to the electronic belt scale. The addition process of raw materials requires that the raw materials be in powder or granular form without agglomeration, and the material flow should be uniform without intermittent operation. Otherwise, it will affect the measurement accuracy and control of the granulation process, as well as affect the product content. The measured material flows into the raw material crusher and enters the next section.

2. Compound fertilizer crushing process:

The mixed fertilizer that is proportioned according to the design requirements is transported to the raw material crusher for raw material crushing, with the aim of crushing various raw materials to a certain degree of fineness, basically ensuring that the particle size of the raw materials is less than 1mm, which is conducive to rolling the materials into balls that meet the standards in the granulator.

3. Compound fertilizer granulation process:

The crushed raw materials enter the conveyor belt conveyor and are transported to the drum granulator for granulation. The solid fertilizer powder to be granulated will rise with the help of the rotation of the cylinder and roll down under the action of gravity. At the same time, Adhesive will be added according to the proportion of raw materials for granulation. The material is wrapped layer by layer on the surface of the granulation nucleus, thickening layer by layer, and gradually granulating. Under the action of the above forces, the material gradually forms a core until it meets the granulation requirements and enters the drying section.

4. Compound fertilizer drying process:

The dryer adopts a cylinder edge drive, flange connection, and direct heat transfer method, suitable for drying compound fertilizers after granulation. The materials that need to be dried enter the sheet drying area equipped with a special combination. Due to the tilting movement of the body and sheet, the materials are continuously lifted by the sheet for sufficient scattering and longitudinal movement. At the same time, they undergo sufficient heat exchange with the high-temperature furnace gas from the hot air furnace, evaporate water, and dry the materials. Materials and flue gas need to be dried and operated in a forward flow and micro negative pressure manner.

The dryer is equipped with a secondary granulation area, which can perform secondary granulation on some non granulated materials, which is beneficial for improving the granulation rate of the system. During the drying process, it is necessary to monitor at all times and adjust the temperature of the dryer head and tail according to the process requirements by adjusting the temperature of the hot air stove and the air volume of the exhaust fan, so as to achieve the drying target of the dried material. The materials that have completed the drying operation are transported by a belt conveyor to the fifth section.

5. Composite fertilizer cooling process:

The rotary cooling machine is mainly used for cooling composite fertilizer products after drying, which can quickly cool hot granular materials to near room temperature. The material entering the cooling machine continuously moves forward under the rotation and tilting action of the body, while the induced draft fan introduces air from the tail of the cooling machine to the head and meets the material countercurrent, taking away the heat of the material. During the cooling process, the cold air also carries some moisture away.

The cooled material is easy to pack in a timely and fast manner to prevent clumping during storage. This machine adopts micro negative pressure operation, reducing pollution and improving the working environment. It has the characteristics of reasonable structure, stable operation, and strong adaptability. The cooled material is transported by a belt conveyor to the sixth section.

6. Compound fertilizer screening and large particle crushing process:

The screening section mainly separates fine powder, finished products, and large particle materials from the materials. Firstly, separate the fine powder in the semi-finished product, and then separate the large particles.

The separated large particles are crushed by a large particle crusher and together with the separated fine powder, they enter the return belt and return to the granulator for granulation. The finished product enters the seventh section.

7. Composite fertilizer packaging process:

The finished product is lifted by a leather elevator to the material bin on the packaging machine, unloaded into the measuring scale and automatically weighed according to the set weight. The weighed material enters the sewing and packaging section through a conveyor for sewing and packaging operations and enters the finished product warehouse.

The complete set of NPK fertilizer equipment includes: automatic batching system, new vertical crusher, rotary granulator, drum screening machine, dryer, cooling machine, packaging scale, etc. The volume size and yield of the compound fertilizer production line equipment vary to some extent, so the price of the compound fertilizer production line equipment naturally varies. The higher the yield, the slightly higher the price.

The trough compost windrow turner can not only ventilate and oxygenate composting materials, but also accurately control the temperature and humidity of composting, so that the composting materials can mature rapidly and basically meet the requirements of large-scale composting production of organic manure. More than 95% of the particles that meet the requirements enter the next process, about 5% of the particles are sent to the pulverizer for crushing and granulation, and the particles that meet the requirements are coated by the coating machine, and the packaging machine is automatically packaged after coating. In this way, the organic fertilizer can be processed and packaged and sold in the warehouse.

The functions of trough compost windrow turner in composting production are as follows
1. Mixing function in raw material conditioning. The main raw materials and various auxiliary materials roughly stacked together according to the proportion can be stirred by the machine to achieve the purpose of tempering.
2. Adjust the temperature of raw material pile. During the operation of the organic fertilizer machine, the raw material pellets are fully contacted with and mixed with the air, and a large amount of fresh air can be kept in the pile, which is conducive to the active production of fermentation heat by aerobic microorganisms, and the stack temperature is increased; when the temperature is high, the fresh air supplement can reduce the stack temperature.
3. Improve the permeability of raw material stack. The turning system can process the material into small lumps, making the thick and dense material pile become fluffy and elastic, and form appropriate porosity
4. Adjust the moisture content of raw material pile. The suitable moisture content of raw material fermentation is above 55%, and the moisture standard of finished organic fertilizer is below 20%. Therefore, in addition to evaporation formed by heat conduction, the forced steam emission will be formed when the material is turned by the compost windrow turner.
5. Realize the special requirements of composting process. Such as the crushing of raw materials, giving a certain shape to the raw material pile or realizing the quantitative displacement of raw materials.

The cow dung processing Organic fertilizer equipment is a complete set of equipment that processes Manure with cow dung as raw material. The cow dung in the dung pan can be pumped into the equipment by the cow dung processing machine through the mud pump, and then dehydrated by the equipment. After treatment, the water content is about 40%.

The method of deep processing cow dung into Manure is very simple. First, select a spacious place, pour the ground with cement, then put the cleaned cow dung on the cement ground to dry, and close the surrounding area with a sunscreen to dry; The purchase of Manure treatment equipment can treat cow dung into granules, which is suitable for sowing, transportation, etc., killing two birds with one stone.

Technological process of cattle manure processing Organic fertilizer production line:

1. Due to the high moisture content of livestock and poultry manure, it is necessary to add crop straw, such as wheat, corn straw, rice straw, peanut seedlings, etc., which are crushed by a straw crusher and mixed with livestock and poultry manure. Hold the livestock and poultry manure in your hand to prevent any leakage of open water.

2. Adding biological strains, the function of biological strains is to quickly heat up, kill harmful bacteria, and achieve deodorization. Generally, after adding biological strains, a temperature of 65 ℃ can eliminate more than 95% of harmful strains. In order to fully ripen and flip evenly, the slot flip machine can perform one flip.

3. At this time, there is animal hair in the fermented Manure, which has a long maturity period, which will affect the granulation effect. At this time, a screening machine is required for screening. In order to protect the environment, a dust cover can be added at this time.

4. Mixing: according to the national requirements for the content of Manure, the content of nitrogen, phosphorus and potassium accounts for 5%. At this time, nitrogen, phosphorus and potassium need to be added, and the mixer needs to be used for mixing.

5. After granulation, the finished product is dried with a moisture content of less than 30% and subsequently packaged for sale.

According to the new national policy, we will accelerate the construction of modern animal husbandry and promote the green development of animal husbandry in the future. Focusing on reducing the generation, harmless treatment, and resource utilization of livestock and poultry breeding waste, we will implement the creation of a demonstration county for green development of animal husbandry, promote the comprehensive utilization of waste throughout the county, and achieve regional agricultural and animal husbandry circulation and zero emissions. Based on the characteristics of small-scale, large-scale, and industrialized livestock and poultry farming in China, adhering to the combination of energy and fertilizer utilization, based on fertilizer utilization, supplemented by energy utilization, and synchronously promoting the resource utilization of livestock and poultry farming waste is the fundamental way to solve the pollution problem of livestock and poultry farming.

Chicken manure has high nutritional value. It is processed into chicken manure Manure for sale, which is a form of recycling aquaculture emissions. It can promote the improvement of environmental protection problems in the aquaculture industry, and can bring additional economic benefits to the farm.

The fertilizer production line for chicken manure production of Manure includes five links:

1. Chicken manure Organic fertilizer fermentation equipment:

The main function of the fermentation part of the Manure production line is to initially reduce the water content in the raw materials of Manure. As we all know, the raw materials of Manure are mainly chicken manure, pig manure, cow manure, sheep manure and other animal manure. Cow manure and sheep manure are OK, and the humidity of chicken manure and pig manure is too high. Especially, the initial humidity of chicken manure is generally above. Such high humidity cannot be directly treated, and must be fermented in a fermentation tank first.

Generally speaking, after about a week of fermentation, the humidity of fresh chicken manure can be reduced to below. Another tip to share is that during the fermentation process of chicken manure, some coarse fiber materials such as bran and wheat bran can be added to reduce the fermentation time and costs.

2. Crushing equipment:

Fermented animal excrement will be caked, and block materials are not easy to dry directly. Therefore, it is recommended to use a small grinder to crush them first before moving on to the next step. In Manure equipment, the crushing part is often necessary.

3. Drying equipment:

Seeing this, some friends may want to ask, why do we need to dry it again if there is no fermentation process ahead. In fact, the fermentation can only control the humidity around. To make Manure granules, the moisture must also be controlled. Therefore, the drying process is also essential.

4. Granulation equipment:

Organic fertilizer granulator is the core link of the whole Manure production line. Generally speaking, we recommend using a combination of granulators and ball shaping machines to achieve granulation functions, and do not recommend using traditional disc granulators. The advantage of doing so is that the particle forming rate is high and the compactness is good.

5. Cooling and packaging equipment:

The cooling and packaging processes can be ignored for small volume users. Small production users can directly air dry and manually bag. Only the complete set of Organic fertilizer production lines with large output need automatic packaging machines.

What is explained here is that a complete chicken manure Organic fertilizer production line is generally not composed of a single equipment, but usually consists of two or three equipment combinations, so the price of chicken manure composting equipment is more difficult to determine, usually between 100000 and millions, depending on the actual situation. As long as the equipment is properly matched and the manufacturer is selected correctly, it can ensure that the user’s investment is small and the later profits are higher.

a. Particle size of raw materials: in order to achieve the granulation particle size of organic fertilizer granulator, the particle size of pig manure and auxiliary raw materials should be less than 10 mm, otherwise they need to be crushed;
b. Suitable material moisture: the optimum fermentation humidity of composting microorganisms is 50 ~ 60%, and the limit humidity is 60 ~ 65%. Therefore, the moisture content of composting materials should be adjusted to 55 ~ 60%. When the moisture content is more than 65%, there is a higher probability of dead tank fermentation.

c. Control of pig manure and auxiliary materials: according to the local agricultural conditions, the production process of pig manure fertilizer can use straw, corn stalk, peanut stem and other organic materials as auxiliary materials. The ratio of pig manure and auxiliary materials can be adjusted according to the requirements of fermentation moisture. (generally 3:1), the raw materials with carbon nitrogen ratio of 20 ~ 80:1 can be selected as the auxiliary materials for composting. Therefore, dry rice straw, corn stalk, deciduous leaves, soybean stem, peanut stem and other organic substances commonly used in rural areas can be used as auxiliary materials for composting and fermentation.
d. Fermentation cycle: after the pig manure, auxiliary materials and inoculated materials are mixed in the tank, the first turning is recorded as the start time of the fermentation cycle. Generally, it goes through a heating period of 3-4 days (5-7 days in winter) to enter the high-temperature fermentation stage. According to the temperature standard, when the temperature of the compost is over 60-70 ℃ for more than 24 hours, the compost windrow turner can be used to turn the pile, and the turning times vary with the seasons. The fermentation cycle is 15 days in summer and 25 days in winter.
e. If it is found that the temperature in the fermentation tank does not exceed 40 ℃ after 10 days in the tank, it can be judged as dead tank and the fermentation start-up fails. At this time, it is necessary to measure the water content in the tank. If the moisture content is more than 60%, it is necessary to add auxiliary materials and inoculating materials and mix them with organic fertilizer machine; if the moisture content is lower than 60%, consider whether the amount of inoculated materials is not enough.
After the pretreated livestock manure enters the organic fertilizer stirring and fermentation device for fermentation, an appropriate amount of nitrogen, phosphorus, potassium and other elements are added according to a certain proportion to make the trace elements meet the organic fertilizer production standard, and then the livestock manure is processed into high fertilizer efficiency, convenient transportation and Use safe and affordable organic fertilizers.

Cow manure is the most troublesome thing for friends in the aquaculture industry, which is equivalent to the problem of dealing with agricultural straw, which is the biggest headache for us people in the agricultural industry. Collect cow dung and add crop straw in a certain proportion. After being decomposed, it can be used as raw material for Manure production, and its value will be greatly increased. Cow manure contains a lot of organic matter nutrients, and crop straw absorbs nutrients from the soil for a long time, so straw also has a certain amount of nutrients. Therefore, when these two materials are mixed to ferment Manure raw materials, they will be rich in more organic matter nutrients.

Operation steps of cattle manure straw Organic fertilizer production line:

1. Organic fertilizer dumper: collect cow dung and add straw in a certain proportion for fermentation. During the fermentation process, a composting machine is used to ferment cow manure thoroughly. Only timely and uniform composting can achieve this. After the material has fully matured and fermented, it can proceed to the next processing step.

2. Semi wet material crusher: After the above equipment has completely fermented and decomposed, the fermented and decomposed materials can be crushed using a crusher. The reason is that the newly fermented and decomposed materials are too large to be processed in the next stage, so a professional crusher is needed for processing. Here we will tell you about the commonly used types of crushers: semi wet material crushers, dual axis horizontal crushers, vertical hammer head crushers, etc.

3. Horizontal mixer: The materials processed by the crushing equipment can be transported to the horizontal mixer for mixing operations. During this period, mixing the materials evenly is a key factor, and the most important thing is which nutrients we want to add to it. During the mixing process, it is the most suitable stage.

4. Organic fertilizer granulator: the stirred materials can be transported to the granulator, thus entering the important granulation stage. I hereby recommend the disc granulator, which is a large and medium-sized granulator and is also the most commonly used equipment. In addition to this equipment, there are also wet stirring toothed granulators and roller extrusion granulators. As for which device to use, you can choose according to the customer’s needs.

5. Organic fertilizer dryer: the reason for passing through the drum dryer is that the moisture content in Manure granules is large, so it needs to be controlled within a certain range;

6. Rotary cooler: the reason for using the rotary cooler is that the processing temperature of Manure particles has reached a very high level through a series of equipment, so we need to use the rotary cooler to reduce the temperature;

7. Rolling screening machine: after being cooled, Manure particles can be screened out from Manure particles of different sizes using a drum screening machine for secondary crushing processing;

8. Organic fertilizer coating machine: the function of the coating machine is to wrap a layer of transparent coating on the surface of Manure particles, and to wrap a layer of coating without affecting the fertilizer efficiency of Manure particles so that the particles are not easy to be crushed and packed; By now, the production of Manure granules has been completed;

9. Organic fertilizer packing machine: the function of the automatic packing scale is to pack and sell the produced granules to the market.

It is not only helpful to improve the surrounding ecological environment, but also to further expand the economic and social benefits of pig farms.
Pig manure composting is a common treatment method. After 10-15 days of accumulation and fermentation, pig manure can be made into high-grade high-quality organic fertilizer; or through drying, it can be further made into organic and inorganic biological formula fertilizer, which can be sold commercially.

The common solution of pig manure is to use Organic fertilizer production lines to process Organic fertilizer
The solid organic wastes, such as pig manure and bedding grass, are piled up in a certain proportion. Under the action of microorganisms, biochemical reactions are carried out to naturally decompose them. With the increase of temperature in the heap, the pathogens, eggs and pupae of the larvae are killed, and harmless and become high-quality organic fertilizer.
At the same time, adding pig manure in batches can make the composting microorganisms in the composting shed rapidly propagate, which can reduce the amount of feces, dehydrate and harmless in a short time. Rapid aerobic composting technology requires the use of organic fertilizer machine ventilation, composting and raising the fermentation temperature, at the same time adding accelerated fermentation microbial strains.
For large and medium-sized pig farms, industrialized fermentation and drying method can be adopted, while for small-scale pig farms or farmers’ self-care, the method of providing fermentation bacteria and farmers’ own composting and fermentation can be adopted.
Pig manure organic fertilizer is different from chemical fertilizer in the market. It can not only prevent and control the damage of various diseases and insect pests on crops, but also improve the soil, reduce the harmful residues of nitrate and heavy metals caused by the large use of chemical fertilizers in the products, inhibit and kill pathogenic bacteria, and provide the nutrition needed by crops Ingredients, coordinate the proportion of nutrients, promote the reasonable growth of crops, create green pollution-free food for you.

The raw materials of Manure come from a wide range of sources, including livestock and poultry dung, fungal spore dregs, distiller’s grains sludge, tobacco, etc., which can be targeted as raw materials of Manure. In the past, these raw materials were troublesome wastes, and the purchase price was relatively low, making the finished Manure more profitable. The production equipment of Organic fertilizer takes granulation equipment as the core to produce finished particles so that the fertilizer can be effectively recycled. A large amount of livestock manure produced by the farm is used to produce green Manure. Manure is returned to the field to plant organic agriculture. Agricultural wastes and agricultural fruits are fed to various livestock and poultry to form a natural green ecological biological chain and maintain Balance of nature.

Equipment and process of Organic fertilizer production line to process manure and produce fertilizer:

1. Organic fertilizer dumper: industrialized fermentation treatment of organic solids such as animal manure, domestic garbage, sludge and crop straw. This equipment conducts comprehensive fermentation on the uniformity of fermentation materials. This allows the front of the fermentation tank to be freely fed or taken out, and waste such as feces can be retained for a long time.

2. Semi wet material crusher is a professional crushing equipment for high humidity, multi fiber materials. Utilizing high-speed rotating blades to crush fibers with good particle size and high efficiency. The semi wet material grinder is mostly used in the production and processing of Manure. It has good effect in crushing chicken manure, humic acid sodium and other raw materials.

3. The mixer has fast mixing speed and good uniformity, and can mix viscous materials with 30% added liquid. During operation, there are two opposite rotating blades and rotors stirring in the middle. Due to the multiple special angles of the blades, regardless of the shape of the material. What is the size and density. Can mix quickly and effectively. Adopting a lower door for fast unloading speed and minimal residue.

4. Granulation: the selection of granulation mode is very important in the production of Manure. The production of granulators of various models and specifications, disc granulators, Manure agitating teeth granulators, new type agitating teeth rotary granulators, and Organic fertilizer granulators has the advantages of uniform granulation particles, stable performance, and long service life. They can produce both Manure and inorganic fertilizer and organic inorganic compound fertilizer. The disc granulator is selected for this process.

5. Drying: Although most of the materials after granulation have already formed particles, the moisture and strength of the particles do not meet the standards, and drying treatment must be carried out. A rotary dryer is a rotating cylinder filled with lifting plates inside. Under the action of the plates, the material is fully lifted to exchange heat with the hot air generated by the hot air furnace. As a result, the temperature of the material is raised, and the moisture in it will quickly diffuse outward due to the temperature and steam partial pressure difference. The diffused moisture is carried away by the wind, achieving the effect of drying the material and improving its strength.

6. Cooling: The dried material is transported to the cooling machine through a belt, and the rotary cooling machine is also a rotating cylinder filled with lifting plates inside. Under the action of the plates, the granulated material is lifted and exchanged with the cold air sucked into the cylinder for heat exchange, cooling to near room temperature, further improving particle strength and reducing moisture.

7. Screening: After cooling, there are powdery materials present. A screening machine is used to screen out all the fine powder and large particles. The fine powder is directly returned to the mixer through the return belt conveyor and mixed with the raw materials before participating in the granulation process again. After the large particles are crushed, they are returned to the mixer through the same return belt conveyor as the fine powder. In this way, a complete production cycle is formed, and the semi-finished products enter the coating process.

8. Packaging: Qualified finished products are packaged using a scale for manual weighing or an automatic packaging machine.

9. Conveyor: Configure belt conveyors, bucket elevators, or screw conveyors according to the actual needs of customers.

Manure is the main source of pollution in chicken farms. Organic fertilizer machine can perfectly solve the problem of fecal emissions, and the treated manure can also bring extra income to the chicken farm. Chicken farms can sell the treated chicken manure to organic fertilizer producers. After a series of processing, the manure can be processed into nutrient rich ecological organic fertilizer.

The fertilizer production process of chicken manure organic fertilizer is as follows:
1. The ratio of raw materials per ton is used to stack strips with unlimited length;
2. Compost fermented by powder;
3. Adding bacteria agent for mixing;
4. Comminution after mixing;
5. Granulation, drying, cooling and grading;
6. The moisture content of the newly made granules is relatively large, so it is necessary to dry the moisture content below 20% of the organic fertilizer standard. After cooling the dried granular organic fertilizer through the cooler, the organic fertilizer particles that meet the requirements can be directly packaged. On the contrary, further grinding, granulation, drying and cooling are needed.
Organic fertilizer equipment is specialized in the treatment of livestock manure, so it can effectively reduce the environmental pollution caused by livestock manure, so as to achieve the purpose of environmental protection. Moreover, the organic fertilizer produced by the organic fertilizer production equipment can effectively regulate the soil, improve the quality and solve the problem of soil hardening.
