Thus, the grinding ball diameter should be larger when the recycle material amount is higher, otherwise, smaller. (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.
