Ball Mill - an overview | ScienceDirect Topics

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%).

Mill (grinding) - Wikipedia

Ball mill. A typical type of fine grinder is the ball mill. A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.
