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.

Modelling SAG milling power and specific energy

Jan 01, 2015· SAG mill power consumption (Pc) in kW, in 4 grinding circuits (GC1 to GC4) at different % of the fresh feed in the size range −6″ +1″ (−152 +25 mm). It is important to notice that the behaviour shown in Fig. 4 is affected by the dependence of the power consumption on the mill sizes. This fact will be addressed later on in this paper.

Simplified hybrid semi-autogenous grinding mill control

Semi-autogenous grinding (SAG) mill control optimisation presents a number of challenges. SAG mills have multiple inputs that are used to control multiple outputs (MIMO process). Secondly, the SAG mill loading process is a ‘high intertia’ process that can be approximated as an integrating process. This means that it is open-loop unstable.
