The XRD-Mill 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 < 0.5 mm to the low μm-range (typically < 10 μm).

The ball and the rod mill basically have the same concept comprising either a 12''x12'' jar with grinding balls or a 12''x24'' jar with grinding rods. The jar is attached to a rotating yoke which is driven by a motor and can be placed in three different positions: Upwards for loading, horizontal for grinding, downwards for discharging.
