Ball Mill

For ball milling, there is an optimum speed where the centrifugal force at the top of the mill is just balanced by the force of gravity. This caused the balls to be lifted to the maximum height before they fall onto the balls below, thus imparting the most kinetic energy. ... Schematic drawing of a high-energy planetary ball mill. The w d and w ...
