Ball Mill Explained - saVRee
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 ...
