Material is crushed underground, stockpiled and then conveyed to a 6.1 x 4.1-m SAG mill. It is powered by a 2.3-MW motor and runs with 8%-12% of the mill’s volume filled with 125-mmdiameter steel grinding balls. Incoming ore varies in zinc and lead levels and hardness. The SAG mill therefore operates at …
considered AG/SAG grinding, even if it was not used in the final grinding circuit design. In the 1980s, many of the grinding plants that were built used FAG or SAG mills, and to decrease overall operating costs, many operators of older conventional milling plants considered and actually retrofitted their plants with AG/SAG mills.
1.. IntroductionIt is generally recognised that the most accurate means for predicting the specific energy of an autogenous (AG)/semi-autogenous (SAG) mill circuit is to pilot the circuit using a 6 ′ × 2 ′ mill (Mosher and Bigg, 2001).However, one of the major drawbacks of this approach is that a relatively large sample is required to do so.
AG/SAG grinding mill can be properly assessed by using the Wio concept, the T 80 used for calculations must be corrected to reflect the additional fines in the AG/SAG circuit product size distribution. metHods And tHeorY of t 80 corrections Essentially, the difficulty with using operating work indices for individual sections in AG/SAG circuits ...

SAG is an acronym for Semi-Autogenous 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.
