Dry grinding in planetary ball mills: Evaluation of a stressing model ...

A planetary ball mill consists of a rotating sun disc (SUN), on which one up to four grinding chambers (GC) are located. The grinding chambers themselves rotate at higher speeds, normally in opposite direction to the sun disc to ensure high forces and a highly random motion and collision pattern of grinding media (see Fig. 1 ).
