Procedure To Operate Aball Millof Cement 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 on inside a mill as speed varies use our online formula the mill speed is typically defined as the percent of the theoretical Mill Speed An Overview Sciencedirect Topics Aug 01 2011 according to available literature the operating speeds of ag mills are much higher than conventional tumbling mills and are in the range of 8085 of the critical speed sag mills of comparable size but containing say 10 ball charge in addition to the rocks normally operate between 70 and 75 of the critical speed
