Different machines to meet all needs
designing the new SAG mill chamber for optimum conditions at the design point is clearly established. For the operating load range just beyond the optimum performance conditions, a linear model was developed to assess the lost production that would result from running the mill at too high a load level.

pressure on mill sizing has resulted in non-flexibility in new SAG mill circuit designs. In order to defend the mill size selected, the owner's engineers need to be able to quantify the loss in productivity that will occur if the SAG mill is downsized. Power based methods allow this calculation to be executed rapidly with good accuracy.

Mill (grinding) Wikipedia. SAG is an acronym for SemiAutogenous Grinding. SAG mills are autogenous mills but 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. Get price
