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

Anyway, I will guess this is a meter diameter mill. Without knowing anything else, start with this: Use around 110 mm center to center for lifter bars. Do not go crazy adding too much lift/height to your bars in hopes of increasing wear life. It will kill capacity. Good luck in your rubber ball mill liner fabrication adventures.
