Working Principle

Material is uniformly fed into the first grinding chamber through the feeding device and hollow shaft. This chamber contains step or wave liners and steel balls of various sizes. As the cylinder rotates, centrifugal force lifts the balls to a certain height before they cascade down, impacting and grinding the material. After preliminary grinding, material passes into the second chamber for further fine grinding. The final product is discharged through the discharge grate.
