Ball Mill Energy-Saving Principle Usually ball mill operates at fixed running speed, and the cylinder speed is determined by belt pulley and gear reduction mechanism (or hydraulic coupling). The rotating speed of ball mill directly affects the movement of steel balls and the grinding process of material.
