How to control the size of fertilizer pellets when you use a disc granulator?
There are many factors that affect the size of the granules, among which the most influential factors are the inclination angle of the disc, the speed of the disc, the position of the scraper and the water content of the raw material, etc.
Control the inclination angle of the disc.
The inclination angle between the disc and the ground is one of the main factors, which will affect the particle size. Generally, the greater the angle of inclination between the pelletizing plate and the ground, the smaller the granules produced. And the suitable inclination angle is 50-60 degrees. You can choose the right angle to install the disc granulator according to the particle size which you need.
Adjust the water content of the raw material.
The water content of the material will also affect the particle size. If the raw material is too dry, it is difficult to form granules during the granulation process. If the moisture content of the raw material is too high, the resulting pellets will be too large. So, when you use the disc pelletizer, you should first adjust the moisture content of the raw materials, and make the moisture content at an appropriate level.
