The wear on the cement mill liner results from abrasion by the charge due to the dominance of shear energy absorption and to the impact resistance of the steel liner. For this mill, the shear energy absorption rate was 9.0 W/m along the first chamber of the mill compared to only 5.0 W/m for the second.
