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 In practice the ball mill is run at just below this speed 70–80

Ball mills can blend and grind at the same time yielding a fine intimate mixture Conventional ball mills are usually limited to a particle size of 1µ after one hour of grinding since gravity causes the particles to fall out of the grinding zone between the media Milling can be done either wet or dry although it is generally possible to get smaller particle sizes wet than dry
