The drum granulator is a method of mixing and granulating powdered basic fertilizers, and is widely used in the granulation of npk compound fertilizers. The principle of npk compound fertilizer drum granulator:
 The material forms a rolling material bed by the friction generated by the rotation of the drum granulator. The squeezing force generated by rolling makes the material containing a certain liquid phase agglomerate into small particles. These small particles become the core and adhere to the surrounding powder. Form larger particles. Since the drum granulator is generally inclined 1°~2.5° to the discharge end, the pellets slowly roll toward the discharge port while rotating with the cylinder. Qualified pellets leave the drum granulator and then enter the dryer for drying, and then go through screening, cooling, coating, packaging and storage. After being crushed, the on-screen material and the under-screen material are sent to the hopper as the return material and the basic fertilizer is granulated at the same time.

The function of the rotary drum npk fertilizer granulator is to pre-granulate the powdery material in the cylinder to form tiny particles with a diameter of 1 to 2 mm. The granulation effect of the drum granulator will directly affect the ball formation rate and product quality.
The drum npk fertilizer granulator effectively prevents the problem of a large amount of powder from flowing out with the granular material, reduces the processing volume and return volume of the subsequent drying, cooling, and screening equipment, and reduces the power consumption of the subsequent equipment. It has a good economic benefit.
The roller extrusion granulator is a key equipment for compound fertilizer granulation, with advanced technology, reasonable design, compact structure, novel and practical, low energy consumption, and matching with corresponding equipment to form a small production line, which can form a certain capacity of continuous and mechanized production. Adopting the eugenic formula, without drying, produced at room temperature, the product is rolled and formed in one go, ensuring that the product quality meets the technical requirements of compound fertilizers. It is an updated product for the production of high, medium, and low concentration specialized compound fertilizers for various crops and the energy-saving and consumption reduction of the compound fertilizer industry.

The new organic fertilizer granulator machine uses the high-speed rotating mechanical stirring force and the resulting aerodynamic force to continuously realize the process of mixing, granulating, spheroidizing, and densification of the 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 0.3-3 mm, and the granulation rate is ≥90%. The particle diameter can be appropriately adjusted by the mixing amount of the material and the spindle speed. Generally, the lower the mixing amount, the speed The higher the particle size, the smaller the particle size and vice versa.

Nowadays, there are a large number of pig farming enterprises in various regions, and with this, pig manure resources are also very abundant. Utilizing this large amount of pig manure to produce organic fertilizer solves the major problem of environmental pollution, while also producing a large amount of pig manure organic fertilizer. The economic benefits are also very considerable. The investment in fully automatic pig manure organic fertilizer equipment can be large or small, and the specific situation needs to be combined with annual production. Equipped with a production line, workers do not need to be equipped too much.

The small-scale organic fertilizer production line equipment refers to a complete set of equipment that uses pig manure, chicken manure, and other livestock and poultry manure as the main raw materials to produce organic fertilizer. The entire equipment includes the process of fermenting cow manure into organic fertilizer and the process of making organic fertilizer into granules and packaging. Some customers with less investment directly choose fermentation equipment, crushing equipment, screening equipment, and packaging equipment to form a set of small powder organic fertilizer production line equipment.

How much is the price of small organic fertilizer production line equipment? The equipment for the powder small organic fertilizer production line is added according to the actual needs and requirements of customers. Therefore, the prices of the entire set of powder small organic fertilizer production line equipment range from tens of thousands to hundreds of thousands.

The equipment used in small-scale organic fertilizer production lines includes flipping machines, drum screening machines, belt conveyors, horizontal mixers, crushers, etc. Compared with the granular organic fertilizer production line, this production line has fewer processes such as granulation, drying, and cooling, and the process is relatively simple.

Process flow of small-scale organic fertilizer production line equipment:

Small organic fertilizer production line equipment must undergo decomposition with a decomposition agent before application, to inactivate and deodorize parasites and their eggs in feces, as well as infectious bacteria, through the process of decomposition. Generally, the equipment for small-scale organic fertilizer production lines consists of a fermentation system, a drying system, a deodorization and dust removal system, a crushing system, a batching system, a mixing system, a screening system, and a finished product packaging system.

Traditional fertilization methods such as manure and garbage not only cause certain harm to the environment, but also can not give full play to the effect. However, more and more organic fertilizer, compound fertilizer, microbial fertilizer and chemical fertilizer are applied. Disc organic fertilizer granulator machine and other granulating equipment have entered people’s life and production.
On the other hand, the disc organic fertilizer granulator can produce organic fertilizer by adding human, livestock, poultry manure and other special processes, which not only has good effect, but also has good effect on the proliferation of microorganisms in the soil. These active factors can adjust the soil structure, improve the quality of fruits and vegetables produced by the planting industry, and improve the soil fertility.

In particular, due to the long-term use of chemical fertilizer, the number of microorganisms in the soil is reduced, and the soil is hardened due to the accumulation of salt. In view of these soil conditions, the application of organic fertilizer made from human, livestock and poultry manure can completely improve the soil quality. Of course, these organic fertilizers need to be processed by hammer crusher, screw conveyor, disc granulator, extrusion granulator and other organic fertilizer equipment.
However, the organic fertilizer produced without organic fertilizer production line treatment or simply by traditional single treatment method will damage the germination and rooting of crop seeds due to hydrogen sulfide and other harmful gases. It can not decompose the harmful substances in feces, and can not fully activate the harmful components accumulated by chemical fertilizer when applied to soil, thus greatly reducing the efficiency of organic fertilizer, Moreover, it will emit a foul smell and pollute the environment.

The working principle of the peanut cake soybean meal organic fertilizer disc granulator:

The material enters the plate through a conveyor belt. As the disc and water spray rotate, the material will better combine with the water in the disc fertilizer granulator. The rotation of the disk causes the raw material to fall and rise, and over time, the particles gradually become larger. After reaching the predetermined diameter in the disc fertilizer granulator, remove the particles from the pot again for the next step.

We are one of the manufacturers of peanut cake and soybean meal organic fertilizer disc granulators. The peanut cake and soybean meal organic fertilizer disc granulator is widely used to produce circular particles of organic and composite fertilizers. The disc fertilizer granulator adopts an arc disc angle structure, with a uniform particle granulation rate of over 93%. The design of the granulation board facilitates intermittent and continuous production, greatly reducing labor intensity and improving labor efficiency.

The process of the drum type npk fertilizer granulator is based on monomer basic fertilizers such as: urea, ammonium nitrate, ammonium chloride, ammonium sulfate, ammonium phosphate (monoammonium phosphate, diammonium phosphate, heavy calcium, ordinary calcium), potassium chloride (Potassium sulfate) etc. as raw materials. After being crushed to a certain degree of fineness, the materials are agglomerated and granulated by humidification and heating in the rolling bed of the drum granulator. During the granulation process, it can also be rotated if conditions permit. The drum npk fertilizer granulator adds a small amount of phosphoric acid and ammonia to improve the granulation conditions.

Process principle of drum type NPK fertilizer granulator

The material forms a rolling bed with the help of the friction generated by the rotation of the drum granulator. The extrusion force generated by the rolling makes the material with a certain liquid phase agglomerate into small particles. These small particles become the core and adhere to the surrounding powder to form larger particles. As the drum granulator is generally inclined to the discharge end of 1 °~ two point five °， Therefore, when the granular material rotates with the cylinder, it slowly rolls to the discharge port along the inclined direction of the cylinder. After leaving the drum granulator, the qualified granules are dried in the dryer, and then screened, cooled, coated, packaged and stored. After crushing, the material on the screen and the material under the screen will be sent to the hopper as the return material and granulated together with the basic fertilizer.

Process characteristics of drum type NPK fertilizer granulator

1. When the moisture content of the material is between 30% and 40%, it can be granulated, and the moisture content of the discharge material is about 30%, which reduces the traditional drying requirement of 70% moisture content and effectively reduces the production cost of organic fertilizer.

2. In the process of granulation, the temperature of 50 ~ 65 ℃ is produced in the cylinder, which reduces the moisture content of the discharged pellets by 5 ~ 8 points, thus reducing the drying cost.

3. The granulation particles are uniform, smooth, round, high strength, and the molding rate of particles is more than 95%.

4. By adjusting the water content of the feed, the size of the discharged pellets can be adjusted to meet the requirements of different pellet sizes.

The small-scale chicken manure granular organic fertilizer production line mainly consists of two parts: fermentation and granulation, which affect the overall price of the organic fertilizer production equipment sales industry. For example, in small and micro chicken farms where the daily production of chicken manure is not large, as a responsible organic fertilizer production equipment sales enterprise, it is recommended that users only purchase the fermentation and composting machine separately. In this way, farmers only need to invest a small amount of funds to meet the needs of harmless treatment of chicken manure.

How much space does a small organic fertilizer processing plant require for equipment? The required site area for equipment in a small organic fertilizer processing plant is related to the production capacity of the plant. Ecological organic fertilizer plants should fully consider long-term development factors when requisitioning land. There is a slight difference in the production site required for producing powdered organic fertilizers and granular organic fertilizers. Due to the addition of equipment such as organic fertilizer granulators, drum dryers, rotary cooling machines, and coating machines in granular organic fertilizer factories, the site area has slightly increased.

How much does a small chicken manure particle organic fertilizer production line cost? The general price of small-scale chicken manure granular organic fertilizer production equipment ranges from 500000 to 600000 yuan. The equipment configuration for small-scale chicken manure granular organic fertilizer production varies depending on the raw materials, and suitable plans can also be made based on the investment budget.
