Grinding media consumption formula for ball mill

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
