The grinding jar is arranged eccentrically on the sun wheel of the planetary ball mill. The direction of movement of the sun wheel is opposite to that of the grinding jars in the ratio 1:-2. The grinding balls in the grinding jars are subjected to superimposed rotational movements, the so-called Coriolis forces.
