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.

Coarseness settings: We compared all mills by grinding pepper on the finest and coarsest possible settings. The finest setting should produce a powderlike consistency and the coarsest setting should be noticeably larger, but still a consistent grind size. For mills with precise settings, we ground pepper on each setting and compared the grounds.

Each time the grate enters the mill charge, the horizontal force of the load in the mill deflects the grate. This stretches the rubber and forces any large material caught in the grate opening along through the grate slot. As the grate leaves the charge, the rubber assumes its original shape. This diaphragming action works the large particles ...
