    How to calculate ball/sag mill charge level? (1 reply) How do you determine the charge level in a SAG mill and/or a ball mill (balls+pulp+rocks) and the interstitial space?With high aspect ratio SAG mills total charge to ball charge ratio should be greater than 2 (up to 25) 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 1516 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 you are using ballsSAG Mill Ball Sizing Grinding & Classification Circuits08/03/2013· ball mill charge calculation – Grinding Mill,Types of How to Calculate Charge Volume in Ball or Rod Mill | To calculate grinding media charge for continuous type ball mill, M = 0 x D2 x L Examplecalculates the grinding charge of a ball mill | Mining
