Current mainstream manure processing equipment:

Zhengzhou Huaqiang Heavy Industry Technology Co., Ltd. independently developed and produced a complete set of organic fertilizer machine, such as manure processing equipment, fermentation equipment, drying equipment, granulation equipment, screening system, and batching system, suitable for the production of organic fertilizer and bio-organic fertilizer. 

The current mainstream manure processing equipment:

1. Dry and wet separator

The wet and dry separator is mainly used for the treatment of manure in animal husbandry. It can separate solid manure and liquid manure from manure, reducing the difficulty of manure treatment, and reducing manure transportation and treatment costs. At present, cow dung can be used as bedding for cow houses after wet and dry separation, which realizes recycling and saves the cost of newly purchased bedding for cow houses. Both pig dung and cow dung can be used as compost after wet and dry separation. Organic fertilizer or return directly to the field. At present, the German FAN company is a leader in this industry, and its product market share is in a leading position. In the fertilizer production process, before the material is decomposed, if there is too much moisture, a dry-wet separator is needed to dehydrate the material.

2. Biogas slurry returning equipment

This equipment is one of the most important equipment for manure treatment. There are many production companies, which are basically tractor-driven, using tractors. Today, the self-propelled liquid return machine produced by the Dutch Prog company is relatively rare. After its launch in 2015, the market responded well, and the order has been queued until 2019.

3. Manure throwing machine

Manure spreaders are also commonly used equipment for manure treatment. Now we will introduce a piece of equipment from Picorite in the United States. This equipment is currently owned by a relatively large amount of equipment in China. It adopts hydraulic push mode. Compared with other manufacturers’ chain methods, it is malfunctioning. Low rate, strong and reliable.

4. Turning and throwing machine

The turning machine is used for the fermentation and turning of organic waste such as livestock manure, sludge, sugar factory filter mud, slag cake and straw sawdust, and is used in organic fertilizer plants, compound fertilizer plants, sludge plants, Fermentation and dewatering operations in gardening farms and bisporus mushroom plantations. When fertilizer granulation, the organic fertilizer granulator is the core fertilizer equipment.

The compost windrow turner in the manure processing equipment is suitable for aerobic fermentation and can be used in conjunction with solar fermentation chambers, fermentation tanks and moving machines. It can be used with the moving machine to realize the function of one machine with multiple slots. The matching fermentation tank can be used for continuous discharging or batch discharging, with high efficiency, stable operation and uniform turning and throwing. The control cabinet is centrally controlled, which can realize manual or automatic control functions. The shovel is sturdy and durable, has the functions of breaking and mixing materials, and the limit travel switch plays a role of protection and limit.

In the past, when people did not pay enough attention to environmental protection, a large amount of chemical fertilizers were used, which not only caused serious soil pollution but also led to a large number of chemical pollution sources in the fertilizer industry. This not only harmed the soil but also posed a threat to people’s physical health. Therefore, for environmental protection, we currently need to solve the primary problem. Therefore, the country is vigorously controlling pollution and advocating the use of organic fertilizers. At present, the application of organic fertilizers in agricultural production is becoming increasingly widespread, and organic fertilizer equipment has gradually become an indispensable mechanical equipment. The development of agriculture and modern industry also occupy an extremely important position. Advanced organic fertilizer equipment is an important way to accelerate the development of ecological agriculture and is also an important equipment for the treatment of livestock and poultry manure.

The organic fertilizer production line can organically treat various livestock and poultry excrement and sewage. Through effective drying and density solidification, it can be converted into high-efficiency granular fertilizer, and can also effectively replace various chemical fertilizers. The organic fertilizer equipment has good economic, social, environmental, and sustainable development benefits and value. It is an ideal, reliable, and environmentally friendly renewable energy machinery worth owning. Organic fertilizer equipment itself has significant advantages and characteristics, which have a very convenient, beneficial, and positive promoting effect on the development of China’s environment and the orderly promotion of comprehensive governance. Currently, organic fertilizer equipment has been widely used by various large, small, and medium-sized manufacturers for comprehensive use, and is a green, environmentally friendly, circular, and energy-saving efficiency machinery.

The disc granulator is a small organic fertilizer granulation equipment suitable for small production units, with a production capacity generally not exceeding 50000 tons/year. It is the primary stage of drum granulation; The suitable raw materials for drum ammoniation granulation are the production process using thermal phosphoric acid and sulfuric acid as raw materials. The liquid phase of the raw materials is relatively large, but the materials generated after neutralization of these liquids exist in solid form, requiring a small drying amount, but the particle strength is small and the appearance is uneven; Spray granulation can fully utilize the concentration device of phosphoric acid and ammonium slurry from the original ammonium slurry granulation, reducing the process cost of producing composite fertilizer raw materials and greatly reducing costs; Spray granulation is the precursor of ammonia granulation, using liquid phase materials with high water content; High tower granulation is a granulation method developed in recent years, which involves spraying raw materials in a high-temperature molten state through a high tower and forming pellets during the falling process.

The new type of bio organic fertilizer produced by organic fertilizer equipment can widely replace various chemical fertilizers, and is currently one of the comprehensive manifestations of resource utilization, recycling, and harmless value

As is well known, pig farm manure has a strong pollution capacity, with a foul odor that can be smelled a few kilometers away, which has caused great pollution to our ecological environment and also seriously affected nearby residents. In order to effectively solve this problem, we will now recommend organic fertilizer equipment to a wide range of friends. After understanding, friends know that the function of organic fertilizer production lines is to mix livestock and poultry manure with crop straw (crushed), and after high-temperature decomposition, the materials are processed into organic fertilizer, thereby achieving the goal of waste recycling and utilization.

1. Pig manure organic fertilizer resources are abundant. There are many raw material resources for pig manure organic fertilizer equipment, and there are hundreds of registered breeding counties in China.

2. Pig manure organic fertilizer has high quality. A pig’s excrement is polluted for a year, and after adding auxiliary materials to form fertilizer, it can be used to ferment 2000-2500kg of pig manure organic fertilizer. The comprehensive organic matter content is higher than 45%, and it is also rich in various nutrients such as nitrogen, phosphorus, and potassium, with a content of over 6%. It is an organic fertilizer that meets national standards and is applicable.

3. The market demand for pig manure organic fertilizer is high. The organic fertilizer production line can not only meet the local fertilizer demand, but also meet the demand of surrounding markets. For soil improvement in farmland, fruit trees, tea planting, and vegetable planting are particularly effective.

4. National policy support. For the aquaculture industry, policy support for the utilization of aquaculture resources in over 500 major aquaculture counties is a strong market proof.

5. The pig manure organic fertilizer equipment is suitable for the trial operation of organic fertilizer production lines in breeding enterprises or large breeding areas, which can effectively reduce pollution emissions from pig farms, achieve harmless treatment of breeding pollution, and achieve the goal of resource utilization.

The pig manure organic fertilizer production line adapts to the strategy of commercializing organic fertilizer management and promotes the formation of the production industry chain. It is a process equipment that integrates industrialization, marketization, and large-scale production development, which is conducive to the sustainable development of agriculture. Not only does it effectively promote the development of ecological agriculture, but it is also a choice for the development of agricultural circular economy.

The production of organic fertilizer production lines is a waste utilization and recycling process. The raw materials used in the production and processing of organic fertilizer include feces, crop straw, household waste, sludge left after sewage treatment, etc. These raw materials are considered useless waste to us, and random stacking of these materials can cause certain harm to the environment, But now we can directly use organic fertilizer production lines to process and produce these materials into organic fertilizers that have many advantages for agricultural production, which can truly be regarded as a way to turn waste into treasure. At the same time, the application of organic fertilizer equipment to process and produce the waste left over in various industries has also achieved recycling between different industries.

The production of powdered organic fertilizers is relatively simple. The production equipment mainly consists of five major components: organic fertilizer stacker, forklift, quantitative feeder, crusher, and screening machine (drum screen or vibrating screen). Before connecting the equipment with the equipment, four sets of belt conveyors need to be used to form a complete production line,

1. There is a belt conveyor above the crusher, which connects the screened large raw materials.

2. A belt above the screening machine is connected to the fermentation material.

3. A belt below the screening machine is connected to the screened finished material, and the finished product is sent to the processing site for weighing and packaging.

4. The warehouse requires a conveyor for loading.

The production line of granular organic fertilizers is relatively complex, mainly using a double roll granulator for granulation. The roller extrusion granulator is a granulation process that utilizes the strong working pressure of machine equipment to polymerize solid materials. This type of granulation feed does not require drying.

The roller extrusion granulator is a widely used granulator in organic fertilizer granulators. The design of the roller extrusion granulator is very reasonable, practical, and low in energy consumption. It can continuously produce one roll forming without the need for drying at room temperature. The ball and socket on the roller skin can be manufactured according to the size and shape of customer needs. Currently, we have produced ball, pillow, semi circular particle, rod, walnut, flat ball, square bar, and so on. New energy-saving products currently used in the compound fertilizer and organic fertilizer industries.

The raw material of granulation equipment of NPK fertilizer production line is made of high-strength wear-resistant alloy stainless steel (the technology is confidential, and the specific material is not disclosed to the public). The precision CNC drilling machine is used for positioning and drilling, and multiple hard surface treatment and ball and socket polishing treatment are carried out to ensure that each ball and socket on the pressure roller can be durable, corrosion-resistant, easy to demould, lasting and stable to produce full particles and smooth surface granules.

Prominent advantages of pelleting equipment in extrusion NPK fertilizer production line
1. Fertilizer granulator machine has high strength wear-resistant alloy stainless steel, congenital superior to ordinary steel.
2. Precision CNC drilling, no deviation of three axis positioning.
The introduction of foreign advanced drilling equipment, three-axis positioning drilling, to ensure that the data such as hole distance and depth are accurate and moving.
3. Multi frequency quenching treatment and shaping of hard surface ball and socket. By analyzing the element composition ratio of raw materials, a number of heat treatment schemes are formulated to achieve high strength and wear resistance of the roller.
4. The ball and socket shall be polished to ensure no residue in granulation and demoulding.
This is the second process of fertilizer granulation, which uses special grinding powder to grind the roller flexibly. Ensure that the ball and socket are smooth and clean to achieve perfect demoulding.

The organic fertilizer chain plate tipping machine is suitable for aerobic composting of organic solid waste such as livestock and poultry manure, sludge waste, straw, etc. The walking system of this machine adopts variable frequency speed regulation, good adaptability to different materials, stable operation, high tipping efficiency, and the ability to perform deep tank operations. It effectively shortens the fermentation cycle, improves production efficiency and product quality. It adopts a variable frequency speed regulation speed walking system, It can adapt well to changes in workload. The walking speed can be flexibly adjusted according to the material resistance situation, making the equipment more adaptable and flexible. It can be equipped with a mobile crane to achieve multi tank equipment operation. If the equipment’s capacity allows, simply adding a fermentation tank can expand the production scale and improve the equipment’s use value

What kind of organic fertilizer flipper is good to use? Different series of flip throwing machines have their own characteristics and advantages, and they are mainly selected based on customer needs.

In today’s society, with the strict investigation of environmental protection and the rapid development of organic agriculture, the use of organic waste in organic fertilizer through biological fermentation has developed rapidly in China. Therefore, the equipment for biological organic fertilizer has been highly praised, and the organic fertilizer production line has achieved the harmless and resourceful treatment of organic waste. However, the organic fertilizer produced by biological fermentation is mostly coarse powder or irregular small pieces. It is particularly inconvenient to use and is very detrimental to large-scale transmission. After years of experience in designing and producing compound fertilizer processing equipment, manure organic fertilizer granulators, bio organic fertilizer granulators, and organic fertilizer granulators have emerged. These devices are suitable for granulation of various organic substances after fermentation, breaking through traditional granulation processes. Before granulation, there is no need to dry and crush raw materials. Spherical, cylindrical and other particles can be directly processed, making the use of organic fertilizers more convenient and promoting the range of use of environmentally friendly organic fertilizers.

The roller extrusion granulator belongs to the extrusion sliding model, and its working principle is: the belt and pulley are driven by an electric motor, transmitted to the driving shaft through a reducer, and synchronized with the passive shaft through a split gear, working in opposite directions. The material is added from the feeding hopper, extruded into shape by rollers, demolded and pelletized, and transported through a pair of chains to the crushing screen studio. The finished particles (balls) are screened and separated, and then returned to be mixed with new materials before pelletizing. With the continuous rotation of the motor and the continuous entry of materials, mass production can be achieved.

Organic fertilizer stirring tooth granulator: It is a molding machine that can manufacture materials into specific shapes. The wet stirring tooth granulator utilizes the high-speed rotating mechanical stirring force and the resulting aerodynamic force to continuously mix, granulate, spheroidize, and compact fine powder materials in the machine, thus achieving the purpose of granulation. This granulation method results in a higher ball forming rate and more beautiful particles, while also saving energy and being efficient and energy-saving.

Organic fertilizer flat film granulator: This machine can produce granular feed, organic fertilizer, cylindrical particles, and can also connect polishing equipment to make cylindrical particles roll into balls in one go, without returning particles, with high ball forming rate and good strength. It is an ideal equipment for organic fertilizer granulation.

The successful development of manure fermentation organic fertilizer equipment has effectively solved the problem of manure resource utilization. It is achieved by mixing cow manure or sludge with organic waste such as straw and corn cob in a certain proportion to achieve a suitable moisture content, and then conducting high-temperature fermentation and ripening. During the fermentation process, continuous oxygen filling and stirring are carried out to naturally heat up the mixed materials, ferment and ripen, kill a large number of bacteria and pathogens, and do not produce odor. The fermentation process is completely closed, It will not cause secondary pollution, and the output will be in a crushed form, which can be directly used for agricultural topdressing. It can also be used as an organic fertilizer raw material for deep processing to become agricultural organic fertilizer with nitrogen, phosphorus, and potassium content meeting standards. On this basis, wheat straw and corn cob truly achieve pollution-free resource utilization.

The organic fertilizer production line for processing organic fertilizers is jointly completed by a series of equipment, including chain plate stacker tank fermentation equipment. Chain stacker is an efficient organic fertilizer production line, and the equipment characteristics of chain stacker are as follows:

1. Deep pool continuous aerobic fermentation, with a short fermentation cycle (7-8 days) and complete fermentation maturity;

2. The forced oxygen supply system adopts a high-pressure Roots blower for air burst, with strong penetration ability of oxygen supply in the material layer, which can ensure that oxygen is evenly supplied to the material from the bottom of the pool without dead corners, and the fermentation is even;

3. The lifting chain adopts a specially designed and dedicated chain, with a long service life, safety and reliability; The lifting mechanism is driven by hydraulic pressure, ensuring smooth operation;

4. Set up an intelligent automatic control system to achieve intelligent control of the working process of the front and rear, left and right, up and down running mechanisms of the tipping machine during the tipping process,;

5. Small footprint, low energy consumption, large production capacity, fast stacking speed, wide adaptability of raw materials, and stable product quality.

6. The use of pool type continuous fermentation technology provides the temperature and oxygen required for fermentation on the basis of beneficial microorganisms, allowing fermentation to be carried out under controllable conditions in the pool, reducing the impact of adverse factors in nature, ensuring year-round production, and adapting it to the characteristics of industries such as aquaculture.

The design of the organic fertilizer chain plate stacker is reasonable, the motor consumes less electricity, and the transmission adopts a hard faced gear reducer, which has low noise and high efficiency. Key parts such as the chain are made of imported components, which are durable. The lifting and lowering use an oil pressure device, and the stacker depth can reach 1.8-2.0 meters. The vertical lifting height of the material can reach 2 meters, and it stays in the air for a long time without aeration. Other forms of stacker can do what three fermentation tanks can do, using a chain plate stacker, One is enough

Ammonium bicarbonate and diammonium phosphate are commonly used fertilizers in agriculture, which are processed by fertilizer production line. So what are the key points of fertilization technology in use?

Ammonium bicarbonate

Ammonium bicarbonate, with about 17% nitrogen content, is the lowest nitrogen content in solid nitrogen fertilizer. Ammonium bicarbonate generally has a moisture content of 5% – 6%, which is easy to deliquescence and caking. When the temperature is lower than 20 ℃, the ammonium bicarbonate will decompose into ammonia and carbon dioxide when the temperature is slightly higher or the moisture content in the product exceeds a certain standard, which will cause the loss of nitrogen fertilizer efficiency. It is a physiological neutral available nitrogen fertilizer, which is suitable for all kinds of crops and soils, and can be used as base fertilizer and topdressing fertilizer. Therefore, it is also used as raw materials and other nutrients, and processed into other special fertilizer by disc granulator after batching.

It can be used as basal fertilizer in furrow. If it can be combined with deep application of cultivated land, its effect will be better. However, it should be noted that the depth of application should be greater than 6cm (sandy soil can be deeper), and the soil should be covered immediately after application, only in this way can the loss of nitrogen be reduced. When ammonium bicarbonate is used as topdressing, the dry land can be combined with intertillage. The depth of application should be less than 2 inches, and the soil should be covered immediately, and the water should be timely watered. The paddy field should keep a shallow water layer of about 1 inch, but not too shallow, otherwise it is easy to damage the root. After application, plough and rake in time to promote the fertilizer to be well absorbed by the soil.

When ammonium bicarbonate is used as topdressing, it is important to remember not to apply it after the rain or before the dew is dry. Ammonium bicarbonate should not be sprayed on the surface of soil no matter it is used as base fertilizer or topdressing, so as to prevent nitrogen volatilization, loss of nitrogen or damage to crops. At the same time, it is necessary to avoid high temperature season and high temperature period, and try to apply it in the season when the temperature is lower than 20 ℃.

Diammonium phosphate

Diammonium phosphate is a kind of quick acting fertilizer with high concentration, which is suitable for all kinds of crops and soils, especially for the crops that like ammonium and need phosphorus. It is suitable to be used as base fertilizer. If it is used as topdressing, it should be applied as early and deep as 10 cm before covering the soil. It should not be too close to the crops to avoid burning the crops. When it is used as seed fertilizer, it can not be directly contacted with the seed. Do not apply diammonium phosphate with water, otherwise most of the nitrogen in it will remain on the surface of the ground, and should not be mixed with alkaline fertilizers such as plant ash and lime to prevent nitrogen volatilization and reduce the availability of phosphorus. We can also use NPK fertilizer granulator to further process it into high-quality compound fertilizer.

The complete set of automated organic fertilizer production line includes: manure dewatering machine, fermentation tipping machine, organic fertilizer crusher, organic fertilizer mixer, organic fertilizer granulator, rotary dryer, cooling machine, drum screening machine, automatic packaging machine, belt conveyor, coating machine, etc.

5. Organic fertilizer granulation machines: Organic fertilizer granulation machines are divided into three types of conventional granulation equipment: disc granulation machines, toothed granulation machines, and three-in-one composite granulation machines. The prices of the three types of granulation equipment are completely different, and customers need to customize them according to their own needs;

6. Organic fertilizer dryer and cooler: The hot air is introduced into the dryer through an induced draft fan to dry the raw materials. The moisture content of the dried raw materials does not exceed 30%. Due to the high temperature of the dried particles, a cooling machine is needed to cool them down;

7. Drum screening machine: The function of this equipment is to screen out particles that do not meet the standard size, and transport them to the crushing process through a belt conveyor for new crushing and granulation. The qualified particles will be transported to the encapsulation process through screening;

8. Organic fertilizer coating machine: Add a layer of coating agent outside the particles to make the appearance of the particles more round and beautiful, sell well, and facilitate long-term storage of materials;

9. Fully automatic quantitative packaging scale: This equipment is the last process in the organic fertilizer production line, and its function is to automatically package particles, with the advantages of saving labor and more accurate packaging.

The organic fertilizer production line can effectively solve the environmental pollution caused by organic waste in animal husbandry, reduce surface water eutrophication caused by pollution, and improve the safety and quality of agricultural products. Fully consuming human green and organic food has laid a good foundation, and the ecological and environmental benefits are extremely significant.
