Application Note SAG Mill Control Semi-Autogenous Grinding (SAG) is arguably the most commonly used method of comminution in mineral processing. In spite of this, many SAG mills do not run at their full potential. Primary grinding consumes a significant percentage of plant operating costs and has a significant impact on the performance of downstream process, such as flotation. Effective SAG
view moreThe ball mill accepts the SAG or AG mill product. Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in

view moreSAG 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.
