The operating principle of the ball mill- Primo Pizza

The operating principle of the ball millconsists of following steps. In a continuously operatingball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls.
