[email protected]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.
