Abrasive grinding ball for coal mill

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

Dec 12, 2019 The hardness of the liner and the grinding ball should be above HRC50. This is mainly because the hardness of the hard phase in the abrasive is 6 ~ 7 on the Mohs scale. It is estimated to be close to HRC60. In theory, the hardness of the grinding medium is greater than or equal to eight percent of the hardness of the abrasive.
