Chat OnlineWhat Is Critical Speed In A Ball Mill. critical speed of ball mill. ball mill critical speed mineral processing metallurgyjun 20 2015 183 a ball mill critical speed actually ball rod ag or sag is the speed at which the centrifugal forces equal gravitational forces at the mill shells inside surface and no balls will fall from its position onto the shell the imagery below helps explain what goes
Chat OnlineCritical 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
Chat Online2015 8 6 If speed of rotation is low it results in insignificant milling action as balls only move in lower part of the drum. If speed of rotation is very high the balls cling to the drum walls due to centrifugal force. Therefore intense grinding action is obtained only when drum rotates at critical speed and here the ball mill rotates at a speed
