SAG Mill Ball Sizing Grinding Classification Circuits

With high aspect ratio SAG mills total charge to ball charge ratio should be greater than 2 up to 2.5 for a coarse mill feed say F80 > 110 mm. If the mill feed size is fine, say 50 mm or 30 mm, then you are looking at a total charge to ball charge ratio of about 1.51.6. These are guidelines and may fluctuate a bit depending on the
