SAG Mill Liner Design - Mineral Processing & Metallurgy

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.


secondary crusher liners last seven months when major shutdowns occur every six. Similarly, increasing primary crusher tonnage at the expense of crushed product size is likely to have a negative effect on SAG mill performance. H-E Parts approach is to look at the whole crushing process from start to finish, and then consult with all
