Calculate Ball Mill Grinding Capacity. 2018-6-21 · A) Total Apparent Volumetric Charge Filling – including balls and excess slurry on top of the ball charge, plus the interstitial voids in between the balls – expressed as a percentage of the net internal mill volume (inside liners).
Tests carried out at the Lafarge Plant in St. Constant in Canada, utilizing the same mill with two different ball charges, have shown that for an equal mill throughput the finer ball charge had the higher mill retention time. Mill throughput could be easily increased with the coarser, more permeable ball charge.
