1. Material characteristics: Different material characteristics have a direct impact on the pelletizing effect of the disc  granulator. The viscosity, humidity, hardness and particle size distribution of the material will affect the granulation process.

2. Disk speed: The disk speed will affect the residence time of the material on the disk, and then affect the formation of particles. Too fast speed may lead to uneven particles, too slow speed may lead to too large particles.

3. Material flow rate: The material flow rate needs to be controlled within the appropriate range to ensure that the material thickness on the disk is moderate. Too much or too little flow will affect the quality and shape of the particles.

4. Disc diameter: disc diameter is related to the flow and residence time of the material, the larger the diameter, the better the flow of the material, but the larger the particle size may be.

5. Granulation mold: The shape and size of the granulation mold directly affect the shape of the particles. The shape and size of the particles produced by different molds will vary.

6. Ambient temperature and humidity: ambient temperature and humidity will affect the viscosity and fluidity of the material, and then affect the granulation effect.

7. Operating parameters: the technical level and experience of the operator and the familiarity with organic fertilizer equipment will also affect the effect of granulation.

8. Equipment maintenance: The maintenance and maintenance of the equipment will affect the operating state of the equipment, thus affecting the granulation effect.

Material composition: The proportion of ingredients in the material, especially the proportion of additives, also affects the quality and shape of the particles.
