Modelling SAG milling power and specific energy

2015-1-1  For SAG mill design, this model could help by generating a correction factor over the power (kW) calculated in the usual way by multiplying the specific energy in kW h/t (determined from experimental testing) by the projected capacity in t/h. The power calculated in the usual way is a basic value which does not consider the variability of the feed size distribution, and could be corrected for
