Cast Grinding Steel Balls

The performance of high Cr balls in secondary grinding depends on the abrasive/corrosive environment of the mill. In most secondary Au, Cu, and Mo grinding, the relative wear rates of high Cr compared to forged steel show a performance improvement of 25 – 30%, similar to that seen in primary grinding.

What is the Effect of Chromium on Wet Grinding Performance

Marked ball wear tests indicated that high Cr balls have higher wear resistance than low Cr balls due to the difference in their passivation behaviors. In wet grinding, nascent metal as well as mineral surfaces are continually being exposed and repassivated due to the removal of passive film by abrasive particles, thereby leading to intense
