    Ball mills 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 7080
