Ball mill. A typical type of fine grinder is the ball mill.A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.

The operating principle of the ball mill consists of following steps. In a continuously operating ball 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.

Although the true wear test of a grinding ball is its life in a real ball mill, the laboratory tests of impact and abrasion may serve as a guide to expected ball life. The two most significant differences found among the commercial balls were the number of impacts to breakage and the impact-spalling rate.
