2019-11-1 • Efficient operation even at higher mill speeds • Operator-friendly smooth mill operation • Significantly improve wear life • Can be precisely designed to handle the given capacity • Can be easily retro-fitted to existing mills. The optimal performance of AG/SAG mills is the key to successful plant operation.

More2019-10-24 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.

More2019-10-24 Once the basic operating conditions have been defined for the mill designer then, and only then, can he begin taking into account shell and head stresses and trunnion bearing sizes required to carry the load and to give the required openings for feeding and discharging the mills. Mill heads are key structural components of any grinding mill.

More2007-9-5 The speed of rotation of the mill determines three basic types of operation modes: slow rotation (cascading), fast rotation (cataracting) and very fast rotation (centrifugation). Each type is characterized by a specific trajectory of motion of the charge in the mill and a different impact of the milling bodies on the ground material.
