Abrasion Test SGS

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 Wet rod mill Rods lb/kWh = Ai Liners lb/kWh = Ai Wet ball mill

Using Abrasion Index for calculating Steel Balls

Also we observe for SAG mills that ore competence and feed size distribution being major influence on rock to steel ratio in the mill are significant factors that influence SAG mill steel wear We ve observed the abrasion index to be a less useful means of predicting SAG mill grinding media wear I have not found the Bond models for mill liner wear to be useful and it s normal to assume a
