Working principle and low price of disc granulator

The raw materials are turned over with the disk, and the particles grow up slowly. Because the disk granulator has obvious classification ability, the large particles float on the top and are continuously discharged from the bottom of the disk. The smaller particles stay in the plate and stick to the newly added materials and continue to grow up. The granulation of the disc granulator is ...
