SAG mills mimic the same shortcoming. It follows that in order to obtain the speciﬁ c energy (SE) to achieve a certain transfer size based on the 80 per cent passing value an inefﬁ ciency factor must be applied to the SE of single stage ball mills rod mills or AG/SAG mills when calculating power according to the Bond Third Theory method.
