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 .

### Optimization of mill performance by using

Ball mills are usually the largest consumers of energy within a mineral concentrator. Comminution is responsible for 50 of the total mineral processing cost. In today s global markets expanding mining groups are trying to optimize mill performances. As a result mines have shifted their emphasis in optimization from ball mills to SAG mills. The rock load in the mill essentially depends on ore characteristics and the discharge rate of broken particles through the discharge end. The discharge rate depends on how efficiently the discharge pump (grate and pulp lifters) operates.
