2016-12-19 abrasion of commercial grinding balls. 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
The positive location between the moil, or drift, and the bolt eliminates the risk of mill damage due to misalignment of hydraulic hammer moils or sledgehammer damage around bolt holes. The use of Easy-Out Bolts also improves safety by removing the
