In a complete fertilizer production line, granulation is the key process in the whole production process. The productivity of organic fertilizer granulator, the strength and shape of granule produced by the granulator directly affect the quality of the final product.
In many fertilizer production enterprises, the most used fertilizer granulation equipment are drum granulator, extrusion granulator and disc granulator. Among the three granulation methods, the disc granulator machine is more suitable for the granulation of organic-inorganic compound fertilizer, and the effect is ideal.
Disc granulator machine 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. The rotating disc with an inclination of 50° rotates the animal material. When the material is brought to a certain height, its own gravity and inertia Under the action of the force, it breaks away from the disc and slides down along the arc track 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 material to agglomerate into granules, thus completing The whole granulation process, according to the principles 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 conveyor equipment below.
As a mature model, the disc granulator has experienced the test of various materials. However, any equipment has its advantages and disadvantages. In the face of different raw materials and production processes, there are also corresponding models. In the actual NPK fertilizer production line, the selection of granulation equipment suitable for materials can make the whole fertilizer production process play a maximum benefit.
