The rotation speed is a key point related to the ball mill efficiency, rotation speed is too great or too small, neither brings a good grinding result. Based on experience, the rotation is usually set between 4-20/minute, if the speed is too great, may create centrifuge force thus the grinding balls stay with the mill perimeter and don't fall.
