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)..

Ball mill Wikipedia
A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
