Grinding Ball Wear & Breakage by Impact & Abrasion TestsOct 23, 2017 . Most commercial balls are made of steel with a carbon content of about 0.5 to 1.0 wt % and heat treated to maximize resistance to abrasion, fracture, and spalling. Fully hardened balls have a tendency to fracture and spall. The odd shaped “balls” found inside ball mills are a result of fracture and spalling.abrasion resistance in ball mill,abrasion resistance in ball mill,A comparison of wear rates of ball mill. (PDF Download Available)The Ball Mill Abrasion (BMA) test was developed by the University of Queensland Materials Performance group to simulate the high stress abrasion conditions experienced in production ball mills. It gives accurate predictions of the service life of wear resistant alloys in mill liner and grinding media applications. In this paper.
