## Ball mill Wikipedia

Aside from common ball mills there is a second type of ball mill called a planetary ball mill. Planetary ball mills are smaller than common ball mills and mainly used in laboratories for grinding sample material down to very small sizes. A planetary ball mill consists of at least one grinding jar which is arranged eccentrically on a so-calledTHE OPTIMAL BALL DIAMETER IN A MILL,then the determination of the optimal ball charge model in a mill. 2. Theoretical background Each grain size corresponds to a definite optimal ball size. The diameter of a ball is determined by the condition that, at the moment of breaking the grain, it has energy E, which is equal to energy E 0 necessary for grain comminution: E E 0. (2)
