Abrasion Index | Mill (Grinding) | Wear Scribd
The Bond Abrasion Test determines the Abrasion Index, which is used to determine steel media and liner wear in crushers, rod mills, and ball mills. Bond developed the following correlations based on the wear rate in pounds of metal wear/kWh of energy used in the comminution process. Rods lb/kWh = (Ai – ) Liners lb/kWh
