A planetary ball mill consists of at least one grinding jar which is arranged eccentrically on a socalled 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 socalled Coriolis ...

The XRDMill McCrone carries out size reduction mainly by friction. 48 cylindrical grinding elements are placed into the grinding jar in eight rows of six elements each. During operation, the jar's circular motion causes the elements to grind the sample from < mm to the low μmrange (typically < 10 μm).
