Size Of A Sag Mill

SAG Mill Ball SizingGrinding & 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 1.5-1.6. These are guidelines and may fluctuate a bit depending on the specifics of your system. I am also assuming your top up ball size is optimized and
