It has been found thai the calculated work index is increased with lower circulating loads for each test sieve size. Otherwise, effect on the Bond work index is mostly for the finer test sieve size (63 micron). OS ş

2017-12-14 distribution affects the SAG mill load and the load affects directly the mill power and the efﬁciency of the mill operation (Van Nierop and Moys, 2001). If a SAG mill has been designed with a conventional power or speciﬁc energy model which do not con-sider the projected feed size distribution it is likely that this mill will reach the

2015-7-1 the SAG mill. This work will look at the effect of removing fine material in the cyclone underflow through fine screening to reduce the re-circulating load. Possible installation of a ball mill to treat the cyclone underflow on milled tonnage is also explored. Freda Rebecca consists of an underground mine and a processing plant.

2021-2-24 Why do ball mills have such high circulating loads?The ball mill grinds. The cyclones separate. But the pump neither grinds nor separates. So what is the purpose of having such a big pump to maintain high circulating loads in our grinding circuit?A recent grinding bulletin addresses this question f

The circulating load around any mill is obviously determined by the actual SAG mill feed which includes the effect of the recycle stream Power Draw, kW 3442 2895 1295 1475 Mill load, % vol
