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 maximum power draw in ball mill is when ball bed is 35-40 % by volume in whole empty mill volume. Considering that ball bed has a porosity of 40 %, the actual ball volume is considered to be 21-24 % of the empty mill.

If the quantity of charge is very less then milling balls will start to collide with each other and no milling will take place. Ball size depends on initial size of charge and ranges from 10mm-150mm dia. For particular material and initial size the ball size must be optimized.

The ball size in a mill has a significant influence on the mill throughput, power consumption and ground material size (Austin et al., 1976; Fuerstenau et al., 1999; Kotake et. al., 2004).
