grinding mill critical speed ball mills companies A Ball Mill Critical Speed actually ball rod or S 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
Get PriceCritical speed depends upon the magnitude and location of the shaft unbalance the length of the shaft its diameter and the kind of bearing support Many practical applications suggest as good practice that the maximum operating speed should not exceed 75% of the critical speed however there are cases that require speeds above the critical speed to work correctly
