Modern mills operate with load cells and mill optimizer's which synchronize the mill weight, power draw, ore feed and weight with density control. Where optimizers are not used, the rule of thumb for a overflow ball mill is a ball load up to about 12 inches below the trunnion discharge- this allows bed expansion by the slurry filling the voids ...

A crucial step in mineral processing – and in Minnesota's iron ore processing – is comminution, a process of crushing and grinding. Large rocks must first be crushed and then ground down to tiny particles to expose the valuable or desired minerals so they can be separated from the waste rock. The prevalence of low-grade and …
