The roller press granulator is also called the extruded organic fertilizer granulator. The extruded organic fertilizer granulator should prevent the granular powdery material from being put into the extruding granulation equipment, and then compact the powdery material by external force. Due to the different external force modes used, the molecules are recombined to make the material appear as cylindrical particles. The entire production and extrusion process is mechanized, without manual operation. However, agitation granulation mainly uses agitation to form the material into a round shape.

The thickness of the bulk product produced by the NPK and organic fertilizer granulator is 5-20 mm, and the surface density is 1.5-3 times that of feed. The large pieces are then sliced, crushed and sieved to obtain the desired granular product. The particles formed by pressure form hot spots at the contact points to melt the material. After the temperature drops, the material cools to form a fixed bridge.

The above is the detailed introduction of the granulation method of the organic fertilizer granulator. We can learn more about them. There are many ways to granulate organic fertilizer. Extrusion granulation can be said to be a commonly used method, so we need to better understand this method. Only in this way can the granulation quality of the organic fertilizer granulating agent be guaranteed. If you want to know more about organic fertilizer equipment, please contact us.
