How to Determine Size Match of Grinding Ball for Ball

(4) Mill liner surface shape also needs to be considered in steel ball gradation. If surface shape cuts down the liner driving force, the grinding ball lifting height will thereby be reduced and the impact force decreased. In this case, large size balls should be adopted. On the contrary, small size ones should be used. SHARE WITH OTHERS
