Application of Operating Work Indices in Autogenous ...

The operating work index concept can be applied overall to AG/SAG circuits, but can be misleading when applied to individual sections (the SAG section or ball mill section). As an example, Table 1 presents AG/SAG pilot plant data for an oxide gold ore. Although the overall Wio is close to the BWi, the calculated figures would suggest that the AG/SAG

MEI Blog: SAG '15 Conference Diary - Barry A. Wills

Sep 10, 2015 · The penultimate paper was presented by Ricardo Fernandez, of Weir Minerals, Chile. He described how AG or SAG milling frequently becomes a bottleneck in an operation as the generation of critical size pebbles, and the subsequent required re-crushing of these, results in an extra burden for the (S)AG mill in the form of a recirculating load of harder and more abrasive material.

Mill (grinding) - Wikipedia

SAG is an acronym for semi-autogenous 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' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.
