Every seven weeks, a shutdown of the SAG Mill was scheduled to assess and maintain the steel mill liners and screen media. Yet the metallurgy team at the mine observed that the feed-end blank panel's mean time to failure was a maximum of four weeks. Depending on the mill discharge grate wear, sometimes only three weeks wear-life was achieved.

Optimizing your SAG mill operation - International Mining
As a result, mines have shifted their emphasis in optimization from ball mills to SAG mills. The rock load in the mill essentially depends on ore characteristics and the discharge rate of broken particles through the discharge end. The discharge rate depends on how efficiently the discharge pump (grate and pulp lifters) operates.
