fertilizer production line

The development of organic fertilizer equipment is getting faster and faster, especially in recent years, in view of the prominent problems such as excessive use of chemical fertilizers, low efficiency, and decline in the quality of cultivated land in my country’s agricultural production, the main goal of bio-organic fertilizer production equipment is to reduce the amount of chemical fertilizers and improve. The quality of cultivated land, the realization of the industrialization of new and efficient biological fertilizers, and organic fertilizers are important measures to improve and improve the quality of crops and maintain nutritional flavor. After the organic fertilizer is decomposed, the active substances required for the decomposition, transformation and synthesis of crops under the action of microorganisms are irreplaceable by any chemical fertilizer, and can be directly absorbed and utilized by plants.

The use of bio-organic fertilizer equipment for harmless treatment of agricultural organic waste, the new organic fertilizer npk manufacturing process technology is more conducive to harmless treatment. Organic fertilizer compost fermentation treatment, using organic fertilizer equipment to process organic fertilizer, does not necessarily require livestock and poultry manure, chicken manure, pig manure, but also can add wheat straw, corn straw mixed farmyard manure, pig manure, pig manure, use organic fertilizer production equipment to carry out Harmless treatment. Adding microbial organic fertilizer fermentation bacteria to compost and ferment, the organic fertilizer granulator produces microbial organic fertilizer, and the organic fertilizer production equipment is an ideal method for the harmless treatment of agricultural waste.

Common granulators include npk fertilizer granulator, roller granulator, disc granulator machine, tooth stirring granulator, and drum granulator. Common granulator bio-organic fertilizer granulator is suitable for the following granulation: bio-organic fertilizer granulation with peat, lignite, organic fertilizer sludge, straw as raw materials; organic fertilizer with chicken manure and other organic fertilizers as the main raw material. Pelletizing; granulation of cake fertilizer with soybean cake as the main raw material; granulation of full-price feed and mixed feed with corn, beans and grass meal as raw materials; granulation of biological feed straw pellets with crop straw as raw material.

Organic fertilizer granulation equipment is one of the most core equipment in organic fertilizer equipment, which directly affects the quality of organic fertilizer particles (such as roundness, uniformity, fertilizer moisture retention performance, etc.). So, what are the differences in the several processes of organic fertilizer granulation? What are the impacts on product quality? Different granulation processes for organic fertilizers require different types of granulators, which directly affect the yield, quality, appearance, price, and other aspects of the product. It can be said that the organic fertilizer granulator is the core of the entire production line.

The organic fertilizer granulation equipment utilizes the high-speed rotating mechanical stirring force and the resulting aerodynamic force to continuously mix, granulate, spheroidize, extrude, collide, compact, and polish fine powder materials in the machine, thus achieving the purpose of granulation. The particle shape is spherical, with a sphericity of ≥ 0.7, a particle size generally between 0.3 and 3 millimeters, and a particle formation rate of ≥ 90%. The size of the particle diameter can be adjusted appropriately by the material mixing amount and the spindle speed. Generally, the lower the mixing amount, the higher the rotation speed, and the smaller the particle. Application scope: This machine is particularly suitable for granulation of lightweight fine powder materials, especially for granulation of organic inorganic compound fertilizers. The finer the basic particles of fine powder materials, the higher the sphericity of the particles, and the better the ball forming quality. It is generally required that the particle size of the material before granulation should be less than 50 mesh. Typical application materials include chicken manure, pig manure, cow manure, carbon black, clay, kaolin, nitrogen, phosphorus, potassium, and other organic inorganic compound fertilizers.

The organic fertilizer special granulation machine is mainly used for granulating various organic materials after fermentation, breaking through the conventional granulation process. The material does not need to be dried before granulation, and after crushing, it can be directly mixed to produce spherical particles, saving energy and high granulation rate. With an organic matter content of over 97, pure organic matter granulation can be achieved without the need for adding binders during granulation. The particles are sturdy and beautiful, and can be sieved and rounded after granulation, reducing drying energy consumption. The moisture content of the raw materials can be between 20 and 50.

Organic fertilizer special granulator 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 has a high ball forming rate, beautiful particles, and also saves energy, which is efficient and energy-saving.

The process flow of the complete set of nitrogen phosphorus potassium compound fertilizer equipment can usually be divided into: raw material batching, raw material stirring, raw material granulation, particle drying, particle cooling, particle grading, finished product coating, and final product packaging.

It can produce various concentrations and types of compound fertilizers (including organic fertilizers, inorganic fertilizers, biological fertilizers, magnetized fertilizers, etc.). Especially for the granulation of rare earth and ammonium bicarbonate series compound fertilizers, it fills the domestic gap and ranks at the leading level in China.

The process of a complete set of nitrogen phosphorus potassium compound fertilizer production line

1. Raw material ingredients: urea, ammonium nitrate, ammonium chloride, ammonium sulfate, ammonium phosphate (monoammonium phosphate, diammonium phosphate, heavy calcium, superphosphate), potassium chloride (potassium sulfate) and other raw materials are prepared in a certain proportion (based on market demand and soil testing results in various regions).

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

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

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

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

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

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

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

The humidity after fermentation of organic fertilizer affects the choice of granulator. Common granulators include npk fertilizer granulator, counter-roll extrusion granulator, disc granulator machine, tooth stirring granulator, and drum granulator. Organic fertilizer fermentation moisture control: 65% organic fertilizer fermentation moisture, how to judge the moisture content? Grab a handful of material with your hand, you can see the watermark on your finger, but it will not drip, it will fall to the ground and scattered open. High moisture content can lead to poor ventilation, slow temperature rise and unpleasant odors. High water content can be achieved by adding straw, sawdust and mushroom residue. When the water content is too low, the fermentation is slow. When the water content is too low, the manure or clean water separated by the solid-liquid separator can be used to ensure the water content.

The difference between the model selection of organic fertilizer granulator is to choose the appropriate granulation method according to the requirements of the material. It’s just a big umbrella, with subdivisions and branches underneath it. It is mainly divided into two categories: dry method and wet method, and the fertilizer granulator machine price is also different.

Extrusion granulation does not require heating and humidifying materials, saving investment and energy, and is also suitable for granulation of heat-sensitive materials such as ammonium bicarbonate and some organic fertilizers. The non-dry extrusion granulation technology and characteristics of the counter-roll extrusion granulator The non-dry extrusion granulation process of the counter-roll extrusion granulator has a wide range of applications in powder particle processing. The organic fertilizer granulator should granulate and process the raw materials fermented within the specified range. It breaks through the characteristics of large reverse material, high water content, low strength, uneven particle size or air-drying in the air, small output and low output of the disc granulator.

The horizontal mixer is a new generation of mixing equipment developed by our company. It has high mixing degree and low residue, making it suitable for mixing formula feed, concentrated feed, and additive premixed feed. The specific characteristics are: the materials are fully mixed, thereby improving the uniformity of mixing; Adopting a novel rotor structure, the minimum gap between the rotor and the casing can be adjusted to close to zero, effectively reducing the residual amount of materials; The special rotor design of this machine can also crush larger materials, with a more reasonable overall structure, beautiful appearance, and convenient operation and maintenance. In order to ensure the normal operation of this machine, please read the user manual carefully to avoid damage to this machine.

The fertilizer mixer can be divided into three main parts:

1. Frame part: All working bodies of the machine are installed and fixed on the frame. The frame of the machine is welded with high-quality carbon steel plates and channel steel, and has passed strict product qualification certification and specific process requirements, achieving the purpose of using this machine.

2. Transmission connection part: The electric motor drives the pulley, triangular belt, and reducer to rotate the main shaft and work. The transmission reducer and the working part of the main machine both use nylon pins as transmission connectors and transmission drives, facilitating assembly and maintenance.

3. Mixing and mixing work part: fertilizer mixer transmitted to the main shaft through a pin coupling by the transmission wheel. The special spiral stirring blades welded to the main shaft rotate synchronously, evenly flipping the materials in the mixing chamber, allowing for sufficient mixing of the materials, greatly reducing the residual amount of the materials. After a period of mixing, the material flows out from the specially designed discharge port below the machine body.

The complete set of organic fertilizer equipment includes: chicken manure dehydrator, fermentation stacker, semi-wet material grinder, horizontal mixer, disc granulator machine, dryer, cooler, trommel screen, coating machine, packaging equipment, belt conveyor, etc. The conveyor is evenly and continuously fed into the npk fertilizer granulator, and it is rounded into spherical particles by the polishing and shaping machine. The belt is conveyed to the finished product silo.

In the organic fertilizer npk manufacturing process, not only the water content of the granules after forming generally exceeds the index and needs to be dried at low temperature, but also the water content of organic raw materials after fermentation is about 30% to 40%, and the water content of the granules after granulation is generally in Between 15% and 20%, the fertilizer quality index requires that the moisture content is less than 14%, and it needs to be dried. Therefore, the drying section is an indispensable and important process in the production process of biological fertilizers, which directly affects the output, quality and energy consumption. It is very important to choose the model and specification of the dryer reasonably and control the process conditions.

1. Due to the different conditions and humidity of the dried materials, there may be large differences. Therefore, when using the dryer, it is necessary to understand the material structure in the production process of the organic fertilizer fermentation tank.

2. The drying characteristics will change with the state of the material. The organic fertilizer fermenter has different moisture characteristics in different materials, so it has a great impact on the internal structure of the equipment.

3. In order to enable the material to be supplied, conveyed and discharged smoothly, the organic fertilizer fermentation tank is heated during the production process. Even if the organic fertilizer fermentation tank can barely operate, it must be considered from the aspects of automation and other engineering. In order to achieve efficient drying, it should also be considered Operation of other units, auxiliary equipment technology, etc. That is to say, the drying operation is the embodiment of a comprehensive technology.

The ground composting and fermentation organic fertilizer production equipment, the walking tipper, is the main unit of a complete set of equipment dedicated to the production of bio organic fertilizers. The machine 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 rides on a pre stacked long strip of fertilizer base, and the fertilizer base raw materials are mixed, fluffy, and moved by a rotating blade shaft mounted under the frame. After passing by, the vehicle is tampered with into new strip piles. Operations can be carried out in open spaces or in workshop greenhouses. Advanced fermentation processes adopt microbial good fermentation, designed based on the principles of good fermentation, allowing fermentation bacteria to fully utilize their functions.

Ground composting and fermentation organic fertilizer production equipment, equipped with drum and knife shaped teeth, is mainly used for flat stacking and 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 break the plate lumps in the fermented materials. It is an essential specialized tool in fertilizer production operations.

The fermentation of walking type composting machine is an important step in the production of organic fertilizer using livestock and poultry manure, and flipping is an important measure to improve composting efficiency and the quality of composting products. Due to the fact that in the process of composting livestock and poultry manure to produce organic fertilizers, the flipping of fertilizers consumes a lot of manpower, material resources, and financial resources, and the research and production of slot type composting flippers can achieve a time-saving and labor-saving production effect.

The highly mechanized design of the walking stacker allows the stacker to achieve automatic feeding and discharging, achieving complete automation. One time flipping saves time and effort, takes only effort, and does not require much investment, which can save manpower and reduce production costs.

The organic fertilizer production process includes: organic material inoculation fermentation (pre-fermentation), main fermentation, pulverization, compounding and mixing, drying, granulation(disc granulator machine,npk fertilizer granulator,drum granulation,etc), cooling, screening, metering and packaging and several other processes.  The compost turning machine is the core equipment of aerobic dynamic composting. As a new type of machinery, it is not yet known in the national product catalogue, but it is rapidly popularized in the family of fertilizer machinery and equipment, and it is the development trend of the composting industry to replace manual operation. Our organic fertilizer equipment manufacturer has reliable performance and rich varieties of turners, and tailor-made solutions for customers. Let’s learn about several common turners.

1. The twin-screw dumper is used for the fermentation and dumping of organic wastes such as livestock and poultry manure, sludge and waste, sugar mill filter mud, slag cake, straw and sawdust. It is suitable for aerobic fermentation and can be used in conjunction with solar fermentation chambers, fermentation tanks and mobile machinery. It can be used with mobile phones to realize the function of one machine with multiple slots. The fermenter can be discharged continuously or in batches. High efficiency, smooth operation, sturdy and durable, even throwing.

2. Hydraulic turners are widely used in organic fertilizer plants, compound fertilizer plants, fermentation and dewatering plants for sludge waste, horticultural farms and BIS mushroom plants. It is suitable for aerobic fermentation, centralized control by the control cabinet, can realize manual or automatic control function, durable bucket, material has certain crushing and mixing functions, and limit travel switch, which can play the role of safety limit.

3. The compost truck is a new product exclusively owned by our company in the market. Composting turnover equipment fills the market gap of large-scale wheeled composting equipment on site. Without a steering wheel, the driver only needs to control two levers, turn left and right, and brake about 180 degrees. The steering wheel is hydraulically balanced. The height of the composting mechanical shaft can be automatically raised and lowered. Depending on the moisture content of the material, the compost pile can be rotated at high speed or at high speed.

The raw materials for the production of organic fertilizers come from a wide range of sources, including plant residues, peat soil, humic acid, cow dung, chicken manure, sheep manure, duck manure, free manure, sludge, sugar mill filter mud, winery lees and so on. In response to different raw materials and the requirements for product quality and product output improvement, various organic fertilizer equipment manufacturers have developed various granulators, with different models and configurations, and fertilizer granulator machine price vary, such as double roller press granulator, stock transfer granulator , disc granulator machine, new organic fertilizer granulator, flat die granulator, ring die granulator, etc.

Double roller press granulator

The double roller press granulator can be used for the granulation of organic fertilizers such as livestock manure, kitchen waste, industrial waste, straw leaves, trough residues, oil and dry cakes, and npk fertilizer granulator for compound fertilizers such as nitrogen, phosphorus and potassium. Granulation of chemicals, feed, etc. The roller extrusion granulator belongs to dry granulation, no drying process is required, high granulation density, good fertilizer efficiency, full organic matter content, advanced technology, compact structure, novel and practical, and low energy consumption. Save the cost of buying dryer and cooler, no need to burn coal in the later stage, which saves a lot of money. If the organic fertilizer produced by machine-seeded farmers should use this granulation process with caution, it is recommended to choose compound fertilizer.

Disc granulator machine

Granulation raw materials include bio-organic fertilizer, pulverized coal, cement, clinker, fertilizer, etc. A disc granulator machine is a more traditional granulation process. Personally, I advocate this granulator, the granulation is smooth, it sells well, the price of the equipment is low, the only downside is the low density. The particle diameter has a large selection range, can be adjusted flexibly, and has a beautiful and uniform appearance. The granulation disc is reinforced with multiple radiant steel plates, which is durable and not easy to deform. The disc of the equipment adopts an overall arc structure, and the granulation rate is as high as 93%.

The small fertilizer crusher is a series of wood crushing equipment invented after years of research and design, which can directly crush wet branches, branches, leaves, straw crops and other fruit tree branches. Reduced the trouble of cooling and drying, and instead directly put it into the machine cavity for crushing operations, the work efficiency has been improved by more than a little.

The small fertilizer crusher is mainly composed of a machine base, feeding equipment, machine casing, cutter head, cutting blade, and electric control. It can crush sawdust of different thicknesses according to the number of blades and different standards of screen mesh.

Small fertilizer crushers are generally portable and can be operated by just one person. The mobile branch crusher is driven by a diesel engine, which solves the problem of difficult electricity consumption. The wheels installed under the machine can be pulled by people or cars for use in cities. The pruned branches are crushed into sawdust by a branch crusher, which facilitates transportation. In addition, sawdust can also be used as fertilizer to directly cultivate flowers, and can be further processed into organic fertilizer to achieve recycling.

The small fertilizer crusher is suitable for departments such as landscaping, forestry, road tree maintenance, parks, golf courses, municipal, nursery, enterprises, property management, etc. It is mainly used to crush various branches cut from pruned trees. After crushing, it can be used as cover, garden bed foundation, organic fertilizer, edible fungi, biomass power generation, and can also be used to produce high-density boards, particle boards, paper industries, etc. After crushing, it can be directly sprayed into the transportation vehicle, with a transportation volume of 1/10 of the original tree branch transportation volume.
