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 ball temperature remains below 100 °C in a SPEX 8000 shaker mill and it is cooler when flatended rather than roundended vial is used, although the milling intensity, as measured by the mechanical dose rate, follows the opposite trend. Temperatures over 200 °C are typical in planetary mills operating at similar milling intensities.
