Ball mill - Wikipedia

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 (ratio: 1:-2 or 1:-1). The grinding balls in the grinding jars are subjected to superimposed rotational movements, the so-called Coriolis forces.
