    critical speed of ball mill when various diameter balls

    Critical speed is defined as the point at which the centrifugal force applied to the grinding mill charge is equal to the force of gravity. At critical speed, the grinding mill charge clings to the mill inner surface and does not tumble. Most ball mills operate at approximately 75 critical speed, as this is determined to be the optimum speed ....The critical speed of the mill, c, is defined as the speed at which a single ball will just remain against the wall for a full cycle.
