How Rod Mills Work. Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. For an equivalent grind a rod mill uses less steel than a ball mill because of the lower speed and better contact between The Critical Speed is used for the determination of ball mill ideal operating speed.

To examine the dependence of critical rotation speed on ball-containing fraction we measured critical speeds at various ball-containing fractions from 0.3 to 0.95 stepped by 0.05. Since at lower fraction than 0.3 we could not observe the centrifugal motion we chose this fraction range. A jar of ball-mill consists of a cylinder and two lids.
