A SAG mill is characterized by its large diameter and short length. It rotates, tumbling its contents violently , causing a breaking action. The mill is lined with wear resistant steel liners which are fitted with lifters to assist with raising the load. The liners are replaced as they wear and the lifting action has degraded.

The SAG mill’s steel liners were failing to meet the required service life. To remedy the problem, the supplier had added more material to the liner design. But this created its own challenges, reducing the effective grinding volume and adding weight to the mill that was pushing bearing pressures dangerously close to limitations. Peening liners.

“Many SAG mill liner designs perform very well in their objective to achieve the desired particle size and protect the mill structure. However, no matter how well a mill is operated, and no matter how well a liner design performs, a mill is only as good as its ability to discharge the slurry out of the mill.

Based on experience, mill-liner designs have moved toward more open-shell lifter spacing, increased pulp lifter volumetric capacity, and a grate design to facilitate maximizing both pebble-crushing circuit utilization and SAG mill capacity. As a guideline, mill throughput is maximized with shell lifters between ratios of 2.5:1 and 5.0:1.
