• How Mill Loadcharge Is Estimated Grinding

Modern mills operate with load cells and mill optimizer39s 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

predicted. Slurry pooling causes the power draw in AG and SAG mills to be lower than a mill without a slurry pool. This phenomenon results in overflow mills usually drawing less power than grate discharge mills that are operating without a slurry pool. This is because by definition overflow mills operate all of the time with a slurry pool.
