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 ...
Aug 15, 2012 The formula was published in Lloyd Sponnenburghs booklet on ball milling, though hes said it originally comes from commercial information and literature on industrial ball mills. Critical speed is the rpm at which the media will be stuck to the side of the jar based on centripetal force. All of the values in the formula are to be used in inches.
