2. Mechanical equipment parameters. The mechanical parameters of organic fertilizer granulator have an important influence on the quality of granulation. Mainly including the main engine speed, pressure, mold aperture and discharge speed. The appropriate speed of the main engine can ensure that the material is fully mixed and extruded in the machine, and improve the quality of granulation. Pressure is also a key factor affecting the quality of granulation, too much or too little pressure will lead to uneven granulation or large particle size. The mold aperture and discharge speed will also affect the particle size and shape of organic fertilizer, which need to be reasonably adjusted according to actual needs.

3. Operation process. The operation process also has an important impact on the quality of organic fertilizer granulation. Reasonable operation process includes material ratio, material pretreatment, granulation process control, etc.

4. Environmental conditions. Environmental conditions also have a certain impact on the quality of organic fertilizer granulation. It mainly includes temperature, humidity, ventilation and so on. Suitable temperature and humidity are conducive to the mixing, extrusion and granulation of materials, while too high or too low temperature and humidity will lead to poor granulation effect. In addition, good ventilation conditions can ensure the gas circulation in the organic fertilizer granulator, reduce the operating temperature of the equipment, and extend the service life of the organic fertilizer equipment.
