    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

  • Feed Size VS Ball SizeGrinding Classification

    One can argue the f50 is a more realistic value since balls wear and the average ball size might be closer to half the maximum. Then the multiple would be closer to 13 times the maximum particle size fed to the ball mill. A f80 = 6 mm would need a ball size of 75 mm.

    Pulp Densities. Pulp densities indicate by means of a tabulation the percentages of solids (or liquid-to-solid ratio) in a sample of pulp. This figure is valuable in two ways—directly because for each unit process and operation in milling the optimum pulp density must be established and maintained and indirectly because certain important tonnage calculations are based on pulp density.
