    How Mill Loadcharge Is Estimated Grinding

    Modern mills operate with load cells and mill optimizers 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 and lifting the steel balls.
