Notes on the granulation process of the roller squeezing granulator

 The organic fertilizer granulator, also known as the roller extrusion granulator, produces cylindrical particles as the finished product. This machine adopts a new technology of bidirectional spiral counter current collision granulation, which enables organic materials to achieve continuous, high-speed, and reciprocating kneading and shearing in the granulation area, forming a high-pressure mechanical flow state collision flow, rapidly changing the molecular structure and granulation properties of materials, significantly enhancing heat transfer, fluidization, and extrusion processes between materials, significantly improving granulation density and sphericity, and significantly reducing energy consumption and template costs.

The working principle of the roller squeezing granulator is that the material is squeezed downwards by the grinding wheel, then cut by a scraper, and then enters the secondary combination polishing and rolling to form a ball in one go; The organic fertilizer extrusion granulator has the advantages of high pelletizing rate, no return material, high particle strength, uniform roundness, low pelletizing moisture, and low drying energy consumption.

Precautions for the roller extrusion granulator during granulation:

1. When using, attention should be paid to the absence of hard objects such as stones and iron blocks in the raw materials. After working for more than ten shifts (8 hours per shift), the rollers need to be cracked and removed. High temperature resistant grease should be added to the bearings to improve their working performance and extend their service life;

2. During granulation, it is strictly prohibited for the pressure roller to come into contact with the template and rotate freely;

3. If the particles appear fragmented or not compacted, the formula of the coarse fiber material should be reduced to within 50%;

4. If there is no granulation or discharge during granulation, the membrane plate should be removed, and after opening each hole, some fiber materials should be added appropriately to restart granulation;

5. The tightness of the belt should be checked regularly, and if there is any oil leakage in the gearbox, the oil seal should be replaced in a timely manner;

6. The vulnerable parts in the flat film granulator include rolling bearings, film plates, pressure roller
