plant ball mill's grinding efficiency (Fig. 1). The functional performance parameters "mill grinding rate through the size of interest," and "cumulative mill grinding rates" from both plant and small-scale tests are applied to this task. A plant media sizing methodology, and industrial case studies, are provided. Background
They dominate these grinding applications because greater stress intensity can be delivered in stirred mills and they can achieve better energy efficiency than ball mills in fine and ultra-fine ...
In fact, in four of the surveys, the SAG mill was found to be more efficient at producing circuit product than the ball mill. Similar results have been seen consistently across all the surveys where this approach has been used, including circuits with AG mills, pebble mills, HPGR, stirred mills and ball mills with fine screens.
