Planetary Ball Mills
In a planetary ball mill, each jar represents a "planet". This planet is located on a circular platform, the so-called sun wheel. When the sun wheel turns, the jar rotates around its own axis, but in the opposite direction. Thus, centrifugal and Coriolis forces are activated, leading to a rapid acceleration of the grinding balls.
