How to Choose A Liner and Ball for A Ball Mill EB Castworld

Dec 12, 2019· How to Choose A Liner and Ball for A Ball Mill. For a long time, a less accurate statement has spread widely, that is, the hardness of the grinding ball is higher than the liner by HRC 3 ~ 5. Asked why, but nowhere to verify. There is no doubt that the liner and the grinding ball are in a cooperative relationship. They and the material together form a three body abrasive wear.
