fertilizer production line

Highly fertile soil has a strong regulating effect on soil water, fertilizer, air and heat, and provides continuous and stable nutrients. Due to the active activity of soil microorganisms and enzymes, the quality and taste of agricultural products are significantly improved, and the fresh-keeping period of stored vegetables and fruits is prolonged. Through the recycling mode of “agricultural waste-biological-organic fertilizer-plant”, it has become a bridge between agricultural waste and crops, opening up a road of sustainable development, with unique advantages.

For example, pig manure contains 15% organic matter, 0.5% nitrogen, 0.5-0.6% phosphorus and 0.35-0.45% potassium. Pig manure has a complex structure, including proteins, fats, organic acids, cellulose, hemicellulose and inorganic salts. It contains more nitrogen, so the carbon to nitrogen ratio is low, about 14:1. Under normal circumstances, it is easily decomposed by microorganisms, releasing nutrients that can be absorbed and utilized by crops.

The organic fertilizer production process is as follows: the organic fertilizer raw materials (livestock manure, domestic waste, litter, biogas residue, waste bacteria, etc.) are fermented and pulverized with a semi-wet material pulverizer, and then nitrogen, phosphorus and potassium elements are added until the mineral elements reach Standard requirements, then mix with a mixer, enter the granulator (npk fertilizer granulator, drum granulation, disc granulator machine, new organic fertilizer granulator, etc.), then dry and sieve, qualified products are packaged, not The qualified products are returned to the organic fertilizer granulator machine after being ground.

The investment scale and product selection plan of organic fertilizer equipment should fully consider the characteristics of raw materials, local soil conditions, regional crop structure, main crops, local resources and market potential, market coverage radius, and the price of organic fertilizer equipment such as fertilizer granulator machine price. Generally speaking, the annual output of new small factories is 10,000 tons (1.5-2.5 tons/hour), 20,000 tons (2.5-3.5 tons/hour), and 30,000 tons (4.5-6 tons/hour).

Organic fertilizer equipment is currently a popular mechanical equipment in the domestic market. With the rapid development of foreign science and technology, the reform and update of domestic organic fertilizer equipment is also very rapid, otherwise it will not be able to keep up with the international pace.

The split gear installed on the driving shaft meshes with the large gear ring fixed on the body, working in opposite directions. The material is added from the feeding end, and is made into particles through the special structure inside the cylinder, and finally flows out through the discharge port. Due to the continuous entry of materials and the continuous rotation of the granulator, mass production can be achieved.

An organic fertilizer production line includes: fermentation turner, pulverizer, feeder, horizontal mixer, organic fertilizer granulator machine, dryer, cooler, screening machine, weighing and packaging machine. This organic fertilizer production line can be used to produce granular organic fertilizer and powdered organic fertilizer.

Ingredients: In the process of making a series of special fertilizers, according to different soil conditions and different crops, inorganic nutrients and concentrated organic matter and trace elements of minerals are added, so that the fertilizer contains a variety of nutrients required for plant growth such as nitrogen, phosphorus, Potassium, sodium, manganese, zinc, copper, etc. According to the formula, nitrogen, phosphorus, potassium and fermented materials are mixed by computer in proportion, and then sent to the granulator for granulation. The formulations of organic and inorganic raw materials are mixed according to different series of products.

How to handle agglomeration in organic fertilizers produced by small-scale organic fertilizer production lines? As is well known, the longer the production time of organic fertilizers, the easier their caking is, while the shorter the caking of organic fertilizers, the fewer the caking. To avoid agglomeration, it is recommended to pay attention to the following points during the production process of small organic fertilizer production lines:

1. Reasonable selection of raw materials

Choose non caking raw materials as our raw materials, such as trace element foliar fertilizers, using iron, copper, manganese, zinc, sulfate and boric acid, ammonium molybdate as raw materials, and magnesium sulfate as the main ingredient. The main raw materials are relatively dry. When the air is not too humid, the fertilizer produced will not clump. Fertilizers using humic acid as the main raw material and amino acids as the main raw material are not prone to clumping. In addition, please choose materials that are as dry as possible.

2. Choosing the appropriate production time for small-scale organic fertilizer production lines

Due to the fact that most of China is located in the northern temperate zone, the rainy season is concentrated in June, July, and August, and this period is also relatively high. Therefore, fertilizers are produced in spring, late autumn, and winter. The possibility of clumping is also low. This is because the air humidity is low and the temperature is not high, which is not conducive to agglomeration.

3. Add some anti caking agents that are not prone to caking

For example, talc powder, humic acid, and other powders. They broke the bridge in the middle. You can also add some surfactants to prevent agglomeration.

4. Reasonable packaging should be used to prevent squeezing

Packaging materials are mainly used to prevent moisture absorption and ventilation. To prevent excessive squeezing during transportation and storage, it can also effectively prevent agglomeration issues.

Manure biomass organic fertilizer equipment supporting facilities need fermentation turner, organic fertilizer pulverizer, drum screener, horizontal mixer, organic fertilizer equipment granulator, organic fertilizer fermentation equipment, rotary drying equipment, cooler, screen Extension, outer film machine, automatic packaging machine, belt conveyor and other machinery and equipment.

The livestock and poultry manure organic fertilizer processing equipment mainly develops a stirring and fermentation device suitable for livestock and poultry manure. It is composed of cabinets, induced draft fans and other devices. The device can complete the harmless treatment, deodorization, aeration, and fermentation of the whole amount of manure at one time, and the whole process of processing can be automatically controlled.

After the fermentation of organic fertilizer is realized, granulation treatment is also required. Common granulators include roller extrusion granulator, disc granulator machine, tooth stirring granulator, drum granulator, and npk granulator machine. Commonly used granulation techniques include agglomeration and extrusion:

①The agglomeration method is carried out in a granulator. It is necessary to mix the raw materials in a mixer according to the required formula, and then transport it to the granulator for granulation, and then carry out drying, screening, cooling, returning, wrapping, and exhaust gas purification. After a series of disposals, the final product of organic fertilizer is obtained. The production capacity of the agglomeration method is high, and the fertilizer particles produced have the functions of smooth appearance and uniform particle size. The extrusion rule is a simple extrusion granulation method.

②The production capacity of the extrusion method is low, and the obtained particles have rough appearance and high water content. The granules produced by each granulator are different, and the fertilizer granulator machine price varies. The granulator can be determined according to the raw materials and output.

Manure organic fertilizer not only strengthens many organic chemical colloidal solutions, but also dissolves many organic compounds into organic chemical colloidal solutions relying on the effect of microbial strains, which greatly increases the adsorption of the soil layer to the surface layer, and causes a lot of viscose It makes the soil particles bond together into a stable soil colloid, improves the soil layer’s water-locking, soil-fixing and air permeability characteristics, and its ability to adjust the ground temperature.

Due to the variety of material forms and drying characteristics in the production of organic fertilizers, if the equipment form is improperly selected, it will bring many problems to the operation of the dryer. Even if it can barely run, its production capacity will be very low. The development of the science and technology of the organic fertilizer production line has brought a lot of room for improvement in our production activities in all walks of life.

The organic fertilizer npk fertilizer granulator adopts high-speed rotation, and the material is turned over at a high speed with the barrel, so that the powder adheres under the high-speed movement, and the processes of mixing, granulation, spheroidization, and densification are continuously realized internally, so as to achieve the purpose of granulation. 

In the field of stirring and agglomeration equipment, the disc granulator machine (sometimes also called a disc granulator) is usually chosen, its ability to produce refined products and it has an affordable fertilizer granulator machine price. It is widely used to process everything from chemical powders, fly ash and soil amendments to minerals and ores, fertilizers and more. Disc granulators are a “tumble growing” or agitated agglomeration device, which means they rely on a liquid binder and motion to form and refine agglomerates. Disc granulators can be used alone or in combination with mixers, the most common being needle mixers.

During the production of powdered organic fertilizer, it mainly adsorbs dust and floating substances floating in the air. When harmless treatment of livestock and poultry manure is carried out, aerobic stack fermentation is generally used. That is to say, in general stack fermentation, it is important to avoid wind and rain during fermentation to reduce organic matter. Therefore, before fermentation, it is necessary to build a rain shelter and stack fermentation tanks.

The chicken manure composting and fermentation overturning machine adds fermented and matured bacteria to produce exquisite organic fertilizer through composting engineering technology. The daily processing of chicken manure as raw material using organic fertilizer fermentation equipment can reach 333 tons, with a water content of 60%. The first stage aerobic composting product is exquisite organic fertilizer, which is brown or grayish brown powder material and can be directly sold after being packaged in plastic woven bags. The second stage product is organic-inorganic compound fertilizer, By adding an appropriate amount of inorganic nutrients to the refined organic fertilizer seeds, a granular compound fertilizer is formed through a mixer, granulator, and drying mechanism.

The chain plate tipping machine is suitable for the 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, has good adaptability to different materials and stable operation, high tipping efficiency, and can perform deep groove operations, effectively shortening the fermentation cycle, improving production efficiency and product quality. The variable frequency speed regulation walking system is adopted, 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. Under the conditions of equipment capacity, just adding a fermentation tank can expand the production scale and improve the equipment’s use value.

Agriculture has always been an important industry that affects people’s ecological environment. Excessive deforestation and predatory farming, as well as the use of fertilizers, pesticides, herbicides and fungicides, lead to environmental pollution and destruction of ecological resource systems. The application range of organic fertilizer granulator machine is: peat fermentation, sludge fermentation, cattle, sheep, chicken, pig manure fermentation, straw fermentation, residue fermentation, mushroom cultivation residue fermentation, domestic waste fermentation, etc. According to the trace elements required by crops, organic fertilizers and bio-organic fertilizers can be made from raw materials, which will not destroy beneficial bacteria and are a green organic fertilizer.

Generally, the organic fertilizer disc granulator machine is divided into two parts, of which the fermentation part is divided into three types of equipment: pre-mixing equipment, dump truck and refining equipment; the organic fertilizer granulator equipment is divided into two mixers—pulverizer—granulator— Dryer— cooler— screener coater— automatic packaging machine, the equipment is connected by conveyor or hoist. Auxiliary equipment, baffle dust removal, cyclone dust removal, ink dust removal, induced draft fan and other equipment. In the past, we needed to adapt to natural developments, which didn’t have much of an impact on our environment.

The model of organic fertilizer granulator is different, and the fertilizer granulator machine price is different. The choice is to choose the appropriate granulation method according to the requirements of the material. Organic fertilizer granulator is just a big general term, and there are subdivisions and branches under it. It is mainly divided into two categories: dry method and wet method. A roller extrusion granulator is a molding machine that can make materials into specific shapes. The roller extrusion granulator has a particularly good granulation effect on ammonium bicarbonate, ammonium chloride, monoammonium phosphate, etc. The granulation rate can reach 85%, no drying is required, the investment is low, and the effect is quick.
