fertilizer production line

The fermentation process of 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 to produce spherical Manure or powder Manure after further drying.

The process flow of the compound fertilizer production line can be divided into: raw material batching, raw material mixing, raw material granulation, particle drying, particle cooling, particle grading, finished product coating, and finished product packaging.

Characteristics of compound fertilizer equipment:

1. Applicability and wide range of raw materials: it is suitable for direct granulation of fermented livestock manure, sugar factory filter sludge, urban sludge, paper making sludge, distiller’s grains, straw, peat and other coarse fiber organic wastes with water content of about 30%, and can produce spherical pure Manure, organic and inorganic fertilizer, and biological Manure.

2. High balling rate and microbial survival rate: The new process can achieve a balling rate of over 90% -95%, and the new technology of low-temperature and high air drying can achieve a microbial survival rate of over 90%.

3. The process flow is short and the operating cost is low. The organic raw materials used in this process do not require pre-treatment such as drying and crushing. The process flow is short and the operating cost is low (if traditional granulation processes such as disc or drum are used, the organic raw materials with a moisture content of about 30% after fermentation need to be dried to below 13% and crushed to over 80 mesh, and the amount of organic materials added cannot exceed 30%).

The production process of high concentration composite fertilizers using drum granulators, the production process of high, medium, and low concentration composite fertilizers using disc granulators, the anti caking technology of composite fertilizers, the production technology of high nitrogen composite fertilizers, and the production technology of organic and inorganic composite fertilizers using urea melt spray granulation, etc.

Crawler type composting machines are more suitable for the mechanism and process requirements of microbial fermentation material composting, and can effectively mix viscous materials with microbial agents and straw powder. Creating a better aerobic environment for material fermentation. Under this loose material property, the materials can be deodorized in 7-12 hours, heated in one day, dried in three days, and fertilized in five to seven days, which is not only much faster than deep tank fermentation, but also effectively prevent the production of hydrogen sulfide, amine gas, indole and other harmful and malodorous gases in the fermentation process, which not only meets the environmental requirements, but also can produce superior biological Manure.

The tracked composter adopts a four-wheel walking design, which can move forward, reverse, and turn, and is operated and driven by one person. During driving, the entire vehicle is mounted on a long strip fertilizer machine, and a rotating knife is hung under the machine to mix, fluff, and move the raw materials of the fertilizer machine. After passing by, a new strip pile is formed, which can be operated in an open field or in a workshop greenhouse.

The crawler type composting machine is equipped with rollers and knife shaped teeth, mainly used for flat stacking fermentation. It has dual functions of flipping and crushing. It can evenly mix materials and bacterial strains such as fecal base materials and sludge, and effectively crush the plate lumps in the fermented materials. It is an essential specialized tool in fertilizer production operations.

(1) Crawler type composting machines are more suitable for the mechanism and process requirements of microbial fermentation and composting of stored feces, which can effectively mix thick stored feces with microbial preparations and straw powder. It is not only much faster than deep tank fermentation, but also effectively prevents the production of hydrogen sulfide, ammonia, indole and other harmful and malodorous gases in the fermentation process, which not only meets the environmental requirements, but also can produce high-quality Manure.

(2) Crawler type composter has the advantages of balanced overall power, low energy consumption and high output, which reduces the survival cost of biological Manure.

(3) The overall structure of the crawler type composting machine is reasonable, with good rigidity, balanced force, simplicity, robustness, safe and reliable performance, easy operation, and strong usability on the yard. Except for the coarse frame, all components are standard parts, making it easy to use and maintain.

(4) Crawler type composting machines do not need to build grooves, and can stack fertilizers into long strips on the ground. Ground stacked fermentation is currently one of the most advanced and cost-effective fertilizer production modes for civil engineering and human resources. The composting machine regularly mixes and crushes materials, and decomposes organic matter under aerobic conditions.

The new process of compound (mixed) fertilizer production by ammonia acid method is a new process of compound (mixed) fertilizer production rising in recent years. Compared with the general process of compound fertilizer production, it has the following characteristics:
1. The reaction heat produced by chemical reaction among liquid ammonia, sulfuric acid, monoammonium phosphate and other materials is directly used in NPK fertilizer manufacturing process of ammonia process to raise the temperature of pelletizing materials (which can make the temperature of pelletizing materials reach 70-80 ℃), reduce the moisture content of materials in the process of pelletizing, and thus reduce the dry drying strength. From the actual situation, the process scheme is about 30% – 40% lower than that of ordinary steam pelletizing process Consumption.
2. The NPK fertilizer manufacturing process by ammonia process uses the high viscosity slurry formed by the reaction of sulfuric acid and monoammonium phosphate to granulate. Compared with the general process, the pelletization rate is increased by about 50%. The production capacity of the same production system can be increased by more than 50%. The production capacity of the general 50000 T / a high concentration fertilizer production line can be up to 80000 T / a after adopting the ammonia process.
3. The product of NPK fertilizer manufacturing process by ammonia method has uniform particles, smooth and round appearance, and high particle strength.
4. The adaptability of raw materials is strong, all kinds of raw materials used in the production of general fertilizer can be used in the ammonia process, and the N-P-K nutrient distribution ratio of the product has a large adjustment range. It can produce all kinds of inorganic compound fertilizer with high and low concentration.

The npk fertilizer production line will generally crush the fermentation materials that have completed the secondary aging and stacking process and enter the mixing and mixing system. Before mixing and mixing, according to the formula, N, P, K and other trace elements will be added into the mixing and mixing system to start mixing.

The mixed materials are transported to the granulation system, and the granulation enters the cooling system after passing through the dryer. The materials are screened after reaching the normal temperature. The particles that meet the requirements enter the coating machine to wrap the film and start packaging. The particles that do not meet the requirements are crushed by the pulverizer and then returned to the granulation system to continue granulation.

Livestock manure from livestock farms and sewage from chemical plants are all sources of pollution. What we can do now is to use Organic fertilizer equipment to solve these culprits of environmental pollution, because Organic fertilizer equipment has been specially developed for livestock manure, which is made into Organic fertilizer after harmless treatment and fermentation. This not only eliminates environmental pollution, Organic fertilizer is also used to supplement organic matter to improve the soil quality, so the state strongly supports the use of Organic fertilizer, which also plays a role in protecting our health.

The Organic fertilizer production line should first control the water content of pig manure below 85%, and then add straw powder, rice bran, corn flour and other auxiliary materials to control the water content between 50% and 70%. Finally, add the special thermophilic bacteria Fermentation starter for pig manure, mix it with a mixer, transport it to the fermentation tank with a forklift, and use the Organic fertilizer composter for full fermentation and decomposition. The fermented pig manure can be granulated. During the fermentation of Manure, the water content and temperature requirements of the material shall be met by using a forklift to transport the fermented pig manure to the forklift feeder, and a belt conveyor is arranged below the feeder to transport it to the grinder for crushing, and then to the Organic fertilizer granulator for granulation. The produced particles have high water content, and then pass through the dryer for drying before entering the cooler to cool the particles and improve the particle strength. Then it is sent to the drum screening machine to screen out unqualified particles, which are then transported by the return conveyor to the secondary crusher for crushing and secondary granulation. Until the qualified particles meeting the customer’s requirements are produced, the packaging machine can be used to seal the packaging finally, that is, the commodity Manure can be sold. There are three different equipment configurations for pig manure Organic fertilizer production equipment to meet the needs of a variety of customers. For small-scale investment, simple configuration equipment can be used, while for large-scale investment, medium or full configuration can be used. The price will vary depending on the configuration.

The Organic fertilizer production line produces a wide range of raw materials for Manure, including chicken manure, pig manure, cow manure and other livestock manure. Such raw materials need to undergo biological fermentation, and then make them reach the harmless treatment standard, so as to further produce commercial Manure.

The complete set of equipment for Organic fertilizer production line is a kind of equipment that uses chicken and pig feces as the main raw materials, adds a certain amount of nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer, magnesium sulfate, Iron(II) sulfate and other substances, uses rice bran, yeast, soybean meal and sugar fermentation for a certain time as biological bacteria, and produces biological fertilizer by mixed fermentation under the effect of sulfuric acid.

The process flow of the Organic fertilizer production line is as follows: Manure raw materials (animal dung, domestic garbage, withered branches and leaves, biogas residue, waste bacteria, etc.) are fermented and then enter the semi wet material grinder for grinding, and then add elements such as nitrogen, phosphorus and potassium (pure nitrogen, Phosphorus pentoxide, Potassium chloride, ammonium chloride, etc.) to make the mineral elements contained reach the required standards, and then there is a mixer for mixing, and then enter the granulation mechanism to granulate, and dry after coming out, Sieve through a screening machine, package qualified products, and return unqualified products to the granulator for granulation.

Equipment process of chicken manure Organic fertilizer production line:

1. The slot type tipping machine, or mobile tipping machine, does not limit the site. The slot type tipping machine needs to build a slot (the length and width of the slot are planned and designed according to the actual size of the site), which is cleaner, healthier, and more environmentally friendly. Materials can be directly stacked in the fermentation tank. With a slot type tipping machine, multiple fermentation tanks can be flipped and fermented through a transfer car.

2. The fermented Manure is moved to the semi-finished product stacking area with a forklift, and the fermented Manure is thrown over by the dumper to facilitate the next step of processing and production every day.

3. The screening machine is used to screen the fermented Manure and sort out the large blocks and sundries in it for further crushing and packaging.

4. The grinder is used to sort out the large sundries and stones in the screened Manure and then crush them, so as to ensure the beauty and quality of the product.

5. The premixing machine can premix the screened and crushed Manure to ensure the stability of product quality, and at the same time, it plays a mixing role in the production of special fertilizers and various compound fertilizers when adding fertilizers and trace elements.

The medium-sized Manure production line with an annual output of 30000 to 50000 tons is the need of developing a circular economy, building a resource conserving and environment-friendly society, conforms to relevant national industrial policies, is conducive to the sustainable development of the company’s production, and can promote the company’s production on the right track of modernization, scale and standardization.

The new type organic fertilizer granulator is one of the commonly used organic fertilizer granulator. It is made up of many spirally arranged agitators with internal structure. It is also called internal rotating agitator granulator. It is also called wet granulator because it is suitable for the granulation of many raw materials with large water content. It is widely used for the granulation of organic fertilizer chemical raw materials.
The working principle of the new organic fertilizer granulator: the new organic fertilizer granulator uses the mechanical stirring force of high-speed rotation and the resulting aerodynamic force to continuously realize the mixing, granulation, spheroidization, densification and other processes of fine powder 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 properly adjusted by the material mixing amount and the spindle speed. Generally, the lower the mixing amount is, the higher the speed is, the smaller the particles are, and vice versa.
Application scope: the new organic fertilizer granulator is especially suitable for the granulation of light and fine powder materials. The finer the basic particles are, the higher the sphericity of the particles is and the better the quality of the pellets is.
Typical application materials: chicken manure, pig manure, cow manure, tanli, clay, kaolin, etc. It is specially used for granulating organic fermentation fertilizer with organic fertilizer raw materials, such as manure and urine of livestock and poultry, compost fertilizer, green fertilizer, sea fertilizer, cake fertilizer, peat fertilizer, soil manure, three wastes, microorganism and other urban domestic wastes. The particles are pellets.
The qualified granulation rate of the new organic fertilizer granulator is more than 80-90%, which is suitable for various formulations. The compressive strength of organic fertilizer is higher than that of disc and drum, and the big ball rate is lower than 15%. The particle size uniformity can be adjusted by the stepless speed regulation function of the machine according to the user’s requirements. The machine is more suitable for granulating organic fertilizer directly after fermentation, saving drying process and greatly reducing manufacturing cost. 

Animal manure production Organic fertilizer equipment Animal manure is a relatively high-quality Manure, which contains about 1.63%, 1.54% and 0.085% of pure nitrogen, phosphorus (P2O5) and potassium (K2O). Livestock and poultry manure must undergo decomposition with a decomposition agent before application. Parasites and their eggs, as well as infectious bacteria, present in livestock and poultry manure, are inactivated and deodorized through the process of decomposition. The production process of Manure from livestock and poultry manure is closely related to the equipment configuration of Manure production line. Generally, the complete set of equipment for Organic fertilizer production line is mainly composed of fermentation system, drying system, deodorization and dust removal system, crushing system, batching system, mixing system, granulation system, screening system and finished product packaging system.

The Organic fertilizer production line equipment has the following advantages: low energy consumption, small floor area, no odor in the operating environment, zero pollution, good ventilation, deodorization only takes 1-2 days. The production line of Organic fertilizer has a compact structure and advanced technology. It uses harmless living bacteria preparation to treat livestock and poultry manure, and carries out biological fermentation under the action of a variety of beneficial microorganisms. After fully decomposing the organic matter in it, nutrients are released. The formed bio heat and high-temperature fermentation process can kill bacteria and eggs, detoxify and deodorize, purify the environment, achieve harmless, resourceful and industrialized treatment, low energy consumption, and stable product quality. The Organic fertilizer production line equipment is the production line equipment used for the factory construction, which is based on the customer’s factory construction site, local raw material sources, land nutrition and planting conditions. As the Manure production line on the market at present, the small Manure production line is convenient to build, and the raw material storage and transportation distance is relatively close. At the same time, it also avoids the drawbacks of super small family workshop Manure processing enterprises. It is the main investment direction for planting and breeding enterprises, as well as fertilizer processing enterprises.

The fertilizer produced by Organic fertilizer equipment can not only save agricultural production investment, increase soil fertility, but also improve yield and optimize crop quality. It is an ideal fertilizer for promoting green food and green agriculture in the world. The Organic fertilizer production equipment we produce is based on the formula to produce all kinds of fertilizers required in the market. It is a fully automated work. With relatively low energy consumption and less labor, it can create higher economic benefits. In the development of modern agriculture in China, Manure equipment has integrated various advanced technologies. With our professional technology and rich production experience, user use will no longer be a problem. We have always regarded user use and equipment quality as prerequisites for production. Only when users have confidence in their use can manufacturers feel at ease.

The rapid fermentation of chicken manure Organic fertilizer equipment to make Organic fertilizer requires the addition of biological fermentation bacteria, and the aerobic fermentation of chicken manure fermentation composter is adopted. Biological fertilizer Fermentation starter can ferment pig, cow, sheep, chicken, duck, quail and other animal feces to produce Manure, and can also ferment and decompose various straws, fallen leaves, withered grass and so on to produce biological Manure, so it is very convenient to obtain materials.

The fermented biological Organic fertilizer in the chicken manure Organic fertilizer production line is a complete fertilizer. It is rich in organic matter, not only nitrogen, phosphorus, potassium and other elements, but also calcium, magnesium, sulfur, iron, manganese, zinc, copper, boron, molybdenum, chlorine and other trace elements. The functional bacteria in the biological Organic fertilizer can not only decompose the mineral phosphorus in the soil, but also the mineral potassium in the soil, releasing phosphorus, potassium and other nutrients, Can provide a continuous supply of nutrients to crops in a sustainable manner.

The process flow of the complete livestock manure production line is as follows: Manure raw materials (animal manure, domestic garbage, dead branches and leaves, biogas residue, waste bacteria, etc.) are fermented and then crushed in a semi wet material grinder, and then elements such as nitrogen, phosphorus and potassium (pure nitrogen, Phosphorus pentoxide, Potassium chloride, ammonium chloride, etc.) are added to make the mineral elements meet the required standards, and then Organic fertilizer mixer is used for mixing, Then enter the Organic fertilizer granulation machine for granulation, dry it after coming out, screen it through the screening machine, pack the qualified products, and return the unqualified products to the granulation machine for granulation.

How to select chicken manure Organic fertilizer production line?

1. The equipment selection of chicken manure Organic fertilizer production line shall adhere to the principle of “high starting point, one-step”, and make selection based on full understanding of Organic fertilizer equipment. According to the characteristics of the project, the production equipment is proposed to be the equipment produced by domestic manufacturers specializing in the production line of chicken manure Manure;

2. The key to equipment selection of chicken manure Organic fertilizer production line is to ensure the requirements of production process, ensure that the products meet the quality standards and the realization of production guidelines, and strive to achieve short process, low energy consumption, easy operation and mature technology.

The higher the production capacity, the greater the investment in Organic fertilizer equipment, and the lower the production capacity, the smaller the investment. If conditions permit, it can be directly made into efficient organic and inorganic compound fertilizer on the basis of Manure, and the market benefit is many times that of Manure.

In the powdered pig manure fertilizer production process, pig manure is firstly collected, mixed with hay and rotten silage to make compost and let it ferment. Fermentation process is divided into: composting, heating, tossing, odorless, loose, composting. When composting, 80% of livestock and poultry manure, 20% of straw, are crushed and mixed. The mixing ratio of straw and manure can be determined according to the moisture content of manure. Generally, 65% of the water content is required for fermentation, that is to say, when the hands are squeezed into a ball, the fingers can see the water, but there is no water dripping, and the solution can be released as soon as the hands are released. Then add corn flour or rice bran and strain, the function of corn flour is to increase the sugar content for strain fermentation, so that the multi-dimensional complex enzyme bacteria quickly take the absolute advantage. Add the prepared mixture into the mixer for mixing, and make sure that the mixture is uniform, transparent and free of lumps.

Production technology of organic fertilizer machine for powdered pig manure
1. Rump fermentation
Use the compost windrow turner to turner the strip stack. When the temperature rises above 55 ℃, pile up once every 1-2 days. After fermentation at 55 ℃ for 10-15 days, put up the pile. (the purpose of turning over the reactor is to promote water evaporation, oxygen entering the reactor, bacteria entering the reactor and rapid propagation and fermentation)
2. Material crushing
Fermented materials can not be sold directly as commodities, because long-term stacking will cause caking and other phenomena. At this time, the bulk material left by the screen needs to be finely crushed by the high humidity material crusher, and the powdered organic fertilizer will be obtained after crushing. (for the early stage fermentation of the powder fertilizer production line, in order to speed up the fermentation process, the auxiliary materials can be added into the pulverizer for crushing)
3. Screening and grading
In order to improve the sales phase, the powdered organic fertilizer can be re screened and the uniform powdered material can be packed. After operating according to the above steps, the pure powder organic fertilizer will be formed after being screened by the roller screen.
4. Packaging of finished products.
The powdered organic fertilizer can be directly put into storage and sold after being packaged by automatic packing scale.

According to incomplete statistics, a cow weighing 600 kilograms has a daily fecal output of 20 kilograms, a urine output of 34 kilograms, and a flushing water volume of 500-800 kilograms (head/day) in the cattle farm. Untreated cow dung is piled up and discharged at random, some directly into rivers, lakes, ditches, ponds, some directly piled up outside the pen and beside the road. In rainy days, a large amount of dung water overflows, causing serious pollution to the surrounding environment, roads, land, water and air, resulting in black and smelly water, dirty air, disease spread, endangering the safety of human and livestock drinking water, and increasing the risk of zoonosis, Seriously endangering human and animal health and even life safety, cow manure has seriously restricted the development of the dairy farming industry.

The powdery Organic fertilizer production line has simple process and low input cost, which is suitable for small and medium-sized enterprises and farmers. It only needs to be equipped with: trough fermentation dumper, semi wet material grinder, drum screening machine, automatic quantitative packaging scale, which can meet the production needs.

Process flow of powder Organic fertilizer production line:

The whole production process of powdered Organic fertilizer can be simply divided into three processes: pretreatment, one-time fermentation and post-treatment. The process flow of the whole powdery Manure production line specifically includes physical dehydration of fresh crop stalks → crushing of dry raw materials → screening → mixing (bacteria+fresh livestock manure+crushed crop stalks are mixed in proportion) → composting and fermentation → temperature change observation → blowing and turning → moisture control → screening → finished products → packaging → warehousing.

1. Pretreatment stage of powdery Manure: after the compost raw materials are transported to the storage yard and weighed by the scale, they are sent to the mixing and stirring device, mixed with the production and domestic organic wastewater in the plant, added with compound bacteria, and the moisture and carbon nitrogen ratio of the compost are roughly adjusted according to the raw material composition. After mixing, the next process is started. If the Manure raw materials are mixed, the C/N ratio is controlled at 23-28, and the water content of the materials after mixing is controlled at 52% -68%. Raw material stacking requirements: height of meters, width of meters, length of any length, and attention should be paid to a naturally ventilated area.

2. Primary fermentation stage of powdery Manure: the mixed raw materials are fed into the primary fermentation tank with a loader to form a fermentation pile. The fan is used to force ventilation from the bottom of the fermentation tank to the top for oxygen supply. The temperature rises to above 60 degrees, and the pile is turned after 48 hours (but when the temperature exceeds 70 degrees, the pile must be turned immediately). When turning the pile, it must be uniform and thorough. Lower layer materials should be turned into the middle and upper parts of the pile as far as possible to fully mature, Determine the number of times the material is flipped based on its degree of maturity. At the same time, the pile will be flipped for about 2 days and supplemented with water (mainly organic wastewater from production and domestic use) and nutrients. The fermentation temperature will be controlled between 500 ° C and 650 ° C for aerobic fermentation. The fermentation cycle for this project is 8 days, with one tank of raw materials entering and one tank of semi-finished products exiting each day. After the fermented semi-finished products are discharged, they are ready to enter the next process.

3. Post treatment stage of powdery Manure: further screen the finished compost, and treat the undersize according to the water content. After sieving and granulating, the material is sent to a dryer heated by biogas in the biogas digester for drying. After adding medium and trace elements in proportion, it is stirred and mixed to make a finished product, which is then packaged and stored for sale. The screened material is returned to the crushing process for reuse.
