Ball Mills – Shell Liners Ball mills primarily experience wear due to abrasion, as opposed to the impact wear seen in SAG mills. For this reason, ball mill liners require alloys with higher hardness to withstand the abrasive environment. Hybrid liners are frequently used in ball mills, where unique design features can significantly influence performance.

There are two "inputs" to a ball mill circuit: the ore fed to the circuit and the power delivered by the grinding mill. A ball mill circuit has two "efficiencies": that of the ball mill grinding environment* and that of the classification system*. A ball mill circuit has two efficiencies because it has two main functions:
