The wall of a ball mill lifts the media as it rotates and at a certain height they fall to grind the cement the mill must not rotate above the critical speed producing a centrifuging action The shell of the mil! is protected by liner plates which may have a rippled profile to optimise lifting, since slippage of the media results in energy loss

If the peripheral speed of the mill is too great, it begins to act like a centrifuge and the balls do not fall back, but stay on the perimeter of the mill The point where the mill becomes a centrifuge is called the "Critical Speed", and ball mills usually operate at 65% to 75% of the critical speed
