However, grinding balls are perfectly suited to the attrition of materials and powders. This is called a ball mill or grinding machine: the balls and the product to be ground are placed in a container, which is set in motion, in rotation. The attrition is then achieved by a mechanical grinding mechanism due to the friction of the balls on the ...

The grinding jars are arranged eccentrically on the sun wheel of the planetary ball mill. The direction of movement of the sun wheel is opposite to that of the grinding jars in the ratio 1:-2 (or 1:-2.5 or 1:-3). The grinding balls in the grinding jars are subjected to superimposed rotational movements, the so-called Coriolis forces.

Ball Mills. For the ball mill to work properly, it must reach critical speed. This is the speed at which the grinding balls start to spin along the ball mills' interior walls. If the ball mill does not reach critical speed, the grinding balls will stay at the bottom. They won't be able to grind the material properly.
