Working Principle

The main motor drives the grinding disc via the reducer, with hot air entering the chamber. Material falls to the disc's center, moves outward by centrifugal force, and is crushed by rollers, forming a material bed for inter-particle crushing. Crushed material moves to the disc's edge, carried by airflow; larger particles return for further grinding. Airflow passes through a separator, where coarse particles are returned, and fine powder is collected. Iron debris falls into the lower cavity, scraped to the discharge port, and removed.
