The dry-free extrusion granulation process of the pair-roller extrusion granulator has a wide range of applications in powder processing granules. Its characteristic is that it does not need to humidify or heat the material, and it can directly process the particles. It can be used for the processing of organic and inorganic fertilizer particles, and also for the processing of feed particles.

Utilizing the non-drying extrusion granulation process, no waste water or waste gas is discharged outside during the production process, and it will not pollute the environment. The extrusion granulation process is short, the operation is simple, and it is convenient to realize the automatic control of production and improve the production efficiency. There are no special requirements on the properties and particle size distribution of the raw materials, so the source of raw materials is relatively wide.

Double Roller Powder Granulator

The five process stages of the production process of organic fertilizer and inorganic fertilizer by roller extrusion granulation

1. Add the qualified raw materials into the mixer according to the ratio requirements and mix them evenly.
2. It is transported to the disc feeder, and the metallic substance in the material is removed during the transporting process.
3. The material in the disc feeder evenly enters the extrusion granulator. The material is forced to pass between the two pressure rollers to be squeezed into flakes. The flakes are broken into pieces by the coarse crusher under the pressure rollers. Sieving. The materials on the screen continue to be crushed and sieved.
4. The semi-finished products are transported to the finished screening machine. The fine particles after screening are returned directly to the disc feeder. The large particles are crushed by the pulverizer and then returned to the disc feeder.
5. The qualified products after screening are transported to the automatic packaging scale for weighing, packaging, and storage.

2. No waste water or waste gas is discharged outside during the production process, and it will not pollute the environment.
3. The extrusion granulation process is short, easy to operate, easy to realize automatic production control, and improve production efficiency.
4. There are no special requirements on the properties and particle size distribution of the raw materials, so the source of raw materials is relatively wide.
5. The production is more flexible, and the product plan can be changed at any time, which is conducive to the production of special fertilizers in small batches.
6. The product has uniform particle size distribution, no segregation or agglomeration.
7. The shape of extrusion granulation product is uniform and not round. Usually, if you need a more round product, you need to further shape the particles.

Double Roller Granulator in Manufacturing

The non-drying extrusion granulation process basically uses a pair-roll extrusion granulator as the main machine of the granulation. FPC has rich experience and good design concepts in the process design of the double-roll extrusion granulator. It has made considerable progress in the upgrading of equipment. Relatively speaking, the granulation rate is high and the return material is low. It is the most popular non-drying extrusion in the market. Pressure granulator process equipment.

In a whole set of organic fertilizer production line, granulation is a key process in the whole production process. The productivity of the organic fertilizer granulator, the strength and shape of the granules produced directly affect the quality of the product.

Rotary Drum Fertilizer Granulating Machine

Among the many organic fertilizer production enterprises, the most used organic fertilizer granulation equipment includes drum granulator, extrusion granulation machine and disk granulator machine. Among the three granulation methods, the disc granulator is more suitable for the granulation of organic-inorganic compound fertilizer, and the effect is more ideal. The disc granulator is mainly composed of granulation disc, spray system, transmission device, bracket and so on.

During production, the powder raw materials are conveyed by the belt conveyor to the granulation disc in the disc granulator, and the rotating disc with an inclination of 50° rotates the animal material. When the material is brought to a certain height, under the action of its own gravity and inertial force, it breaks away from the disc and slides down along the arc-shaped trajectory to complete the rolling required for granulation. At the same time, the liquid injected by the spray system will be evenly sprayed on the rolling materials to agglomerate them into granules, thus completing the entire granulation process. According to the principle applied in this granulation process, we can call it agglomerate granulation process. With the continuous addition of raw materials, the manufactured particles fall across the edge of the disk under the action of centrifugal force and fall into the belt conveying equipment below.

As an old model, the disc granulator has experienced the test of various materials, but any equipment has advantages and disadvantages. With the diversification of raw materials, organic fertilizer equipment manufacturers are constantly developing new granulation equipment. In the production of ordinary organic fertilizers, there is a new type fertilizer stirring tooth granulator, which has high production efficiency and good product quality. In terms of organic-inorganic compound fertilizer, there is also a new type compound fertilizer granulator, which is improved on the basis of the stirring tooth granulator, but it has solved the problem of material sticking to the wall. It’s also very beautiful. The diversification of raw materials has promoted the diversification of organic fertilizer granulation equipment. Only by purchasing equipment suitable for your own materials can the whole set of organic fertilizer equipment be effective.

The organic fertilizer granulator requires materials and moisture during the production process. How to add water for good pellet production, how to make the granulator faster and more efficient, the proportion of water added is very important. Next, let me talk about the addition of water to the granulator.

In the production process of organic fertilizer granulator, the material is required to have viscosity. Some raw materials are relatively loose after fermentation and it is not easy to pelletize. Some water or binders must be added to increase the viscosity of the materials. The organic fertilizer equipment disc granulator and the rotary drum type fertilizer granulator adopt agglomeration granulation method. During the granulation process, water or binder is added to ensure that the material can be granulated smoothly. The new organic fertilizer granulator adopts wet granulation, and the materials after fermentation can be directly granulated without other processes. The double roll press pelletizer is produced by a non-drying room temperature process, which is suitable for granulating materials with relatively low viscosity or relatively low water content.

The new organic fertilizer granulator is an organic fertilizer granulating equipment that continues to be updated and reproduced with the development of agriculture, technological improvement, and diverse needs. The new organic fertilizer wet granulator can realize the selection of materials. As long as the various organic substances after effective fermentation can be granulated by the new organic fertilizer granulator, the limitations and obstacles of the traditional process are broken. Moreover, it is not necessary to stop the processing, crushing and drying tasks of the raw materials before granulation, and can directly realize the batching processing and direct granulation. It not only saves a small amount of labor input, but also realizes the effective reduction of costs, but also realizes the improvement of task efficiency, which is convenient and fast, and the effect is satisfactory. The new organic fertilizer granulator also achieves a higher organic content, realizing the exclusive manufacturing of pure organic fertilizers.

The emergence of the organic fertilizer granulator has brought a great contribution to the development of agriculture. Mastering the above knowledge can develop production more effectively.
