This means that when the sun wheel rotates once, the grinding jars rotate twice in the opposite direction. Figure 4. In the planetary ball mill, centrifugal and Coriolis forces permit grindings down to the submicron range. The result of grinding of alumina (Al 2 O 3) at 650 min -1 in the PM 100 is shown in Figure 5.
