PDF Design Method of Ball Mill by Discrete Element

The grinding rate of gibbsite in tumbling and rocking ball mills using fins was well correlated with the specific 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 operating conditions for the rocking ball mill could be estimated by the specific impact energy
