1. The material is composed of feeding device through the hollow shaft spiral evenly into the mill first.

2. Warehouse with ladder plate or corrugated plate, built in different specifications of steel ball, cylinder rotate falling after the ball to a certain height, the centrifugal force is generated on the material and grinding effect.
