Mill Speed Critical Speed Mill Speed No matter how large or small a mill ball mill ceramic lined mill pebble mill jar mill or laboratory jar rolling mill its rotational speed is important to proper and efficient mill operation Too low a speed and little energy is imparted on the product
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 shell’s 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
Ball Mill Progressive Industries Inc ball mill critical speedAPT Ball Mills have been successfully run at speeds between 60 and 90 percent of critical speed However most APT Ball Mills operate at speeds between 65 and 75 percent of critical speed The larger the diameter the slower the rotationformula for critical speed of ball mill
