For overflow ball mills the charge should not exceed 45 of the mill volume . For grate discharge mills the charge should occupy about 50 of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge He and the radius of the mill R i.e.

Planetary ball mills. A planetary ball mill consists of at least one grinding jar which is arranged eccentrically on a so called sun wheel. The direction of movement of the sun wheel is opposite to that of the grinding jars according to a fixed ratio. The grinding balls in the grinding jars are subjected to superimposed rotational movements.
