The grinding rate of gibbsite in tumbling and rocking ball mills using fins was well correlated with the spe cific impact energy of the balls calculated from Discrete Element Method simulation. This relationship was successfully used for the scaleup of a rocking ball mill, and the optimum design and
Dec 09, 2009· Strict process control when grinding the ball shaft and ball nut raceways ensures that the contact angles will meet design specifications. Good control of the grinding process should allow for a small range of ball sizes from the nominal. A large ball range from nominal allows the contact angle to shift and can result in decreased life.
