The trend of “livestock farms+organic fertilizer plants=organic planting” is a major development trend. As livestock farms, in order to deal with the problem of manure pollution in livestock farms, using organic fertilizer equipment to process manure into organic fertilizer is a relatively simple, low technical difficulty, and relatively low equipment investment cost treatment method. So how do small organic fertilizer processing plants process and produce standard, high-quality, and locally suitable organic fertilizers?

The specific operation process of the organic fertilizer production line is as follows:

1. Organic material fermentation and decomposition: Due to the high moisture content of fresh livestock and poultry manure, a large amount of auxiliary materials such as straw and husks are often added. During the stacking process, organic fertilizer fermentation equipment is used to flip, promote oxygen, evaporate excess water, and control the internal temperature of the pile to prevent the inactivation of beneficial bacteria.

2. Material crushing: Due to the need for standing for about a week to mature and decompose in the later stage of fermentation, a large amount of agglomeration and other phenomena will be generated, which is not conducive to the mixing, granulation and other stages in the later stage.

At the same time, in order to meet the fertilizer requirements of local soil and crops, a certain amount of N, P, K, and other composite fertilizers need to be added. These composite fertilizers need to be crushed in advance to facilitate the next step of mixing and stirring (if the tubers of straw and other materials are large before fermentation, simple crushing treatment should also be carried out to avoid affecting the normal operation of the tipping machine)

3. Mixing and stirring: Here, a horizontal mixer is mainly used for mixing. The fermented and evenly crushed organic materials are fully mixed with the composite fertilizer. The mixture is stirred every 3-5 minutes and then transported directly to the fertilizer granulator by a conveyor for granulation.

4. Fertilizer granulation: As the mixed material to be granulated is an organic and inorganic mixture, a new type of granulator will be selected for granulation. The granulator uses a rotating drum and internal stirring teeth to rotate at high speed, resulting in high pelletizing rate, high yield, and strong adaptability. When the production capacity is low, you can choose either a regular disc granulator or a toothed granulator. For specific information, you can contact our technical manager for a detailed introduction.

5. Drying and cooling: This is to quickly evaporate the excess water inside the particles, which is beneficial for packaging and bagging, and prolongs the storage cycle. If the production is small, only the dryer can be installed or this link can be ignored.

6. Screening and grading: According to one’s own needs, screening can be carried out, and products with consistent particle size and quality can be sold as finished products. This can improve the economic value of the product, while other small particles, semi-finished products, powders, etc. can be returned to the crushing process.

7. Customers can also perform processes such as rounding and granulation, coating and coating according to their needs, further enhancing the product value of their fertilizers.

The process flow of organic fertilizer production line can be reduced according to the actual situation of the breeding farm, and the production line of granular or powdered organic fertilizer can be selected according to the demand of surrounding markets.

The roller extrusion granulator is widely used in fertilizer production due to its significant advantage of extrusion molding process. Usually npk fertilizer extrusion process is more commonly used. Due to the physical characteristics of npk fertilizer itself, the specific gravity of the granular fertilizer produced , Roundness and strength have all got good standards. All this is attributed to the roll skin of the extrusion granulator, and this article will take you to understand the relevant knowledge of the roll skin.
For the roller extrusion npk fertilizer granulator, it is the pair of roller skins that affects its granulation effect. Small round pits of the same depth are regularly distributed on the roller skin. When two round rollers rotate opposite to each other, the two half pits coincide with each other to form a hollow circular mold. In the production of fertilizer, the material is continuously pressed into these small round molds by the roller skin, thereby forming round particles. These particles are not only beautiful in appearance, but also strong, and will not be broken due to collision or pile pressure.

For granules, it is very important whether the small round pits on the surface of the roller skin of the npk fertilizer granulator are processed according to the standard. It not only affects the shaping of the fertilizer, but also affects whether the finished fertilizer is hulled. If the hulling is not smooth, the fertilizer will be It will stick to the small round pits and cannot be processed into finished round particles. Compared with the organic fertilizer extrusion granulator, the chemical fertilizer on the roll skin is not cleaned in time, and its corrosiveness will affect the roll skin.
Another thing about the roller skin is its material. The roller skin will be worn to a certain extent under the action of external force. Generally, good roll skins are made of high-grade materials and undergo a rigorous heat treatment process, which greatly improves the hardness of the roll skin of the extrusion granulator and prolongs its service life. 

Dry material mixing and granulation: In the early process of mixing solid powder materials to make powdered fertilizers, the process steps of granulation, drying, coarse-grain crushing and fine-grain return to continue granulation are added, and finally dry granules are obtained. Finished product. Urea-general calcium-potassium chloride aggregate type compound fertilizer belongs to this category.
Adding part of the dry powder of liquid raw materials for mixing and granulation: When mixing solid powder materials for granulation, the drum granulator introduces sulfuric acid, phosphoric acid or nitric acid, and supplements a certain amount of water vapor, and blows in gas ammonia to neutralize the added acid or neutralization. And acidic components in solid materials. Relying on the enthalpy brought in by the neutralization reaction heat, saturation and steam, the liquid phase (including the salt solution and water generated by the reaction) is introduced to promote agglomeration and granulation. The granulation of urea-ammonium phosphate-potassium chloride series and ammonium chloride-ammonium phosphate-potassium chloride series materials belongs to this category.

Slurry granulation process: The slurry produced by the reaction material is coated on the surface of the returned particles, and the particles are enlarged through continuous slurry coating, and then the particles are dried and evaporated to remove water, thereby obtaining a hard and Granular product with good fluidity. Due to the wide range of particle size distribution of the returned material, the coating and bonding effects always occur at the same time. For certain materials and npk fertilizer granulator models, a kind of granulation is always the dominant. The granulation of ammonium phosphate fertilizer belongs to this category.
Melt granulation process: the molten slurry (melt with very low moisture content) is cooled or condensed to make it into granules. Ammonium nitrate melt granulation belongs to this category.

The organic fertilizer crusher is suitable for crushing block materials in the production of composite fertilizers, and is also widely used in industries such as chemical, building materials, mining, etc., especially for crushing high humidity materials with a water content of over 40%, such as fruits and vegetables, wine tank mushroom residue, traditional Chinese medicine residue, etc. This machine uses high-strength hard alloy chain plates and chains with synchronous rotational speed during the crushing process. The inlet and outlet design is reasonable, and the crushed materials are uniform, not easy to stick to walls, and easy to clean.

Working principle of organic fertilizer crusher: The peanut shell walnut shell organic fertilizer crusher adopts a two-stage rotor for upper and lower crushing, without the design of a screen bottom, a high alloy wear-resistant hammer head, and bidirectional gap adjustment technology. If the hammer is worn, it does not need to be repaired, and can be used continuously by moving the position of the hammer. Adjusting the gap between the hammer head and the lining plate can control the particle size of the material. Only one person is needed for easy operation, which is not only safe and reliable, but also convenient for maintenance. The material passes through the upper rotor crusher to form small particles, and then is transported to the lower rotor to continue crushing into fine powder, achieving the effect of material powder and hammer powder. Finally, the material is directly discharged from the discharge port.

After long-term use, the semi wet material crusher has been proven to be convenient to use, efficient, with large production capacity and simple maintenance. Suitable for crushing various block fertilizers and other medium hardness block materials. The chain crusher can crush undeveloped phosphate fertilizer, calcium superphosphate, and various phosphate compound fertilizer products with a moisture content of 14% and a free acid content of 6%. Many phosphate compound fertilizer production plants use vertical chain crushers and other crushers to bond materials to the inner wall of the machine casing during production operations, resulting in the inability to proceed with production. The horizontal chain crusher enables continuous production of the crushing process in the production of phosphate and compound fertilizers, improving production efficiency.

Organic fertilizer granulator machine: disc granulator, new organic fertilizer granulator, drum granulator, roller extrusion granulator and so on, the most commonly used granulation equipment is the above. In the production of organic fertilizer, the selection of granulator is usually decided by many factors, such as raw materials, output and price.
The new organic fertilizer granulator is a granulating equipment specialized in the production of organic fertilizer. It is also called an internal stirring tooth granulator. It is suitable for granulating materials with relatively large fibers. The shape of the finished product is oblate and needs to be processed by a rounding machine. It can be processed into a circle.

Both the drum granulator and the disc granulator belong to the agglomeration method.Compared with the disc granulator, the drum granulator relies on the temperature of the high granulation to increase the amount of liquid in the basic material, and promote the material to be more Balls are formed under low water content, which has the advantages of easy drying, energy saving and consumption reduction. But when the process conditions are not well controlled, the return material is high.
The roller extrusion granulator is a room temperature granulation equipment, which does not produce a large amount of dust and smoke when working, and it is suitable for a wide range of materials.
Price of organic fertilizer granulator machine:
1. If you want to buy granulator, no matter what kind of granulator you buy, it should be integrated according to the actual conditions.
2. Parameters of organic fertilizer pelletizer most businesses provide you with various parameters to facilitate your purchase.
3. There are many kinds of price of organic fertilizer granulator, and the merchants have made it clear on the price. Even if you don’t understand it, we can help you understand it clearly. A variety of fertilizer granulators produced by our company are available for you to choose.
In order to understand the fertilizer granulator machine price, we should first know what kind of fertilizer granules we want to produce, and then we should choose the appropriate fertilizer granulator according to our own production capacity.

With the improvement of fertilization equipment, the granulated fertilizer is easy to store and transport. Fertilizer storage does not agglomerate. The drum granulator does not produce a large amount of dust and smoke when it is working, and it has a wide range of applicable materials. It can granulate materials that cannot be processed by other granulators, and has a high granulation rate.

Features of drum granulator:
(1) The drum granulator is one of the key equipment in the compound fertilizer industry.
(2) It is suitable for hot and cold granulation of compound fertilizers and large-scale production of compound fertilizers with high, medium and low concentrations.
(3) The npk fertilizer granulator shell adopts special rubber plate lining or acid-resistant stainless steel lining plate. The raw materials are not easy to stick to the wall of the cylinder and play a role in corrosion protection. The drum granulator has large output, good economic efficiency and resource saving.
(4) The ball has high strength, good appearance, corrosion resistance, wear resistance, low energy consumption, long service life, and convenient operation and maintenance.
The drum granulator is suitable for large-span, high-depth fermentation and granulation of organic waste such as pig, sheep, cattle, chicken and other livestock manure, sludge garbage, sugar factory filter mud, slag cake, straw sawdust and other organic waste.

As a general organic fertilizer production, the steps mainly include crushing, fermentation, granulation, drying, and other steps. However, if you want to meet the local needs, you need to add a certain amount of N, P, K, and other composite fertilizers, then mix and stir evenly, and use physical extrusion to make particles.

The inorganic fertilizer composite fertilizer extrusion granulator is produced using a non drying room temperature process, with a production capacity of 1-1.5 tons/hour, 1.5-3 tons/hour, and other specifications. It can produce various concentrations and types of compound fertilizers (including organic fertilizers, inorganic fertilizers, biological fertilizers, magnetized fertilizers, etc.). This equipment has low investment and good economic benefits. The complete equipment layout is compact, scientific and reasonable, energy-saving and consumption reducing, stable operation, reliable operation, and convenient maintenance.

The working principle of the inorganic fertilizer composite fertilizer extrusion granulator is that the belt pulley is driven by an electric motor, and the transmission belt is transmitted to a pair of high-pressure roller bodies with sliding mold shells through a reducer for relative work.

The two rollers of the inorganic fertilizer compound fertilizer extrusion granulator are interacted with each other by a set of opposing gears. The two rollers of the extrusion granulator are directly driven by two output shafts on a dedicated reducer to achieve the purpose of extrusion molding. During production, the raw materials enter the feed hopper and are relatively extruded by the high-pressure roller body. After demolding, they flow to the lower part of the roller body for crushing and forming.

Organic fertilizer granulator machine is used to granulate various organic wastes (straw, livestock manure, cake fertilizer, peat, etc.) after fermentation, and process them into spherical, rod-shaped or other amorphous particles. Compared with traditional farmyard manure, pelletized organic manure not only promotes the reuse of organic waste materials, but also has the characteristics of high permeability and high fertilizer efficiency, so it is more and more widely used.
The existing granulators of organic fertilizer not only need to adjust the formula of fertilizer, but also adjust the temperature and humidity, especially the temperature and humidity conditions are very critical to the formation of organic fertilizer. However, the existing organic fertilizer granulator machine generally ignore the influence of temperature and humidity on the formation of granulation, resulting in the phenomenon of organic fertilizer sticking, caking or moistening, mildew before leaving the factory, low product quality and high fertilizer efficiency It needs to be improved. 

The output power of the organic fertilizer granulator machine is transmitted by the reducer through the transmission shaft, which drives the equipment to rotate as a whole. The front section is the forced feeding system, the back section is the internal stirring teeth, and the cylinder wall is lined with stainless steel. After the material enters, the stirring teeth force the material to form a ball. The ball forming rate is 100%, and the material moisture requirement is 25% – 45% It is not suitable to add too much humic acid, because humic acid will produce high temperature due to kneading, so that the material moisture is not balanced, which is easy to cause problems such as material not forming, equipment blocking and so on.

The new type of organic fertilizer granulator machine is mainly used for the granulation of all kinds of organic materials after fermentation. It breaks through the conventional granulation process. Before granulation, the materials do not need to be dried. After crushing, the spherical particles can be processed directly. It saves energy and has higher pelleting rate. The content of organic matter is more than 97, so the granulation of pure organic matter can be realized without adding binder. The granule is solid and beautiful. After granulation, it can be sieved and thrown round to reduce drying energy consumption. The moisture content of raw material can be between 20-50.

During the inspection and purchase of organic fertilizer granulator machine, it is easy to be dazzled by some virtual websites, various advertisements and letters, or confused by the so-called low quotation, resulting in the purchase of inferior products, causing great losses. In order to ensure that you can purchase reliable products and rely on them for long-term use, the following suggestions are put forward for your reference:
1. Look at the production scale, product development technology, processing and manufacturing capacity of organic fertilizer granulator machine manufacturers.
2. It depends on whether the materials and parts are standard or not, on the processing and production technology, and on the product test results and measures.
3. How about after-sales service and technical ability.
