There are basically two groups of Grinding Mill Liners. Ones with a HIGH PROFILE and those with a LOW PROFILE. The high profile liner is designed to give the media the higher lift. This type will be used in mills that are designed for primary grinding and as a result require the impact of the higher cascade. Ball mills working as the …

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.

Greatly accelerated liner wear due to high-energy impacts on the liner. For a 5m diameter mill these will be in excess of 8m.s-1, for a 10m diameter mill these exceed 12m.s-1. This causes high chrome liners to spall and crack and they may even fracture. This can reduce liner life from a year to less than a few months.
