Background: SAG mills are generally the bottle neck in a mineral processing plant and therefore directly influence the amount of gold produced. In the current configuration however, the SAG mill is susceptible to unstable operation in the form of sudden discharge end surges, during which the mass flow can suddenly increase by up to 500%.

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.
