2019-12-10the rotation speed is a key point related to the ball mill efficiency, rotation speed too great or too small, neither bring good grinding resultased on experience, the rotation is usually set between 4-20minute, if the speed too great, may create centrifuge force thus the grinding balls stay with the mill perimeter and dont fall.
