Mill (grinding) Wikipedia
SAG is an acronym for semiautogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' () in diameter, powered by a 28 MW (38,000 HP) motor. A SAG mill with a 44' ( ...Get Price
Modelling of the Performance of AG/SAG Mills
Figure 8 shows plots of Fi for impact breakage which were fitted to data obtained from a 6’*2’ pilot ag/sag mill treating a very competent copper/gold ore. The figure shows the results together with the 95% confidence intervals from 2 extreme cases ag and sag with 12% balls . The results are very encouraging in that the relationships are ...Get Price
