Ball Mills are generally used to grind material 1/4 inch and finer down to the particle size of 20 to 75 microns To achieve a reasonable efficiency with ball mills they must be operated in a closed system with oversize material continuously being recirculated back into the mill to be reducedHow can I determine the best RPM for Dry Ball Milling machine in order to let the balls to fall from the best angle s in rpm = 423/sqrt D d with D the diameter of the mill in meters
