why lead zinc ore grinding mills prefering casting high chrome grinding
During the wearing process in the ball mills, the hardness of forged balls decrease more quickly from the surface to the inside than for the high chrome grinding balls. Used forged balls have a low hardness than the high chrome balls at the same radius. Grinding parameters are in favor of high chrome grinding balls in the same conditions. Baudouin
