### Model Predictive Control for SAG Milling in Minerals

Model Predictive Control for SAG Milling in Minerals Processing Steven J. McGarel, Rockwell Automation Introduction SAG and ball mills are generally accepted as the largest power consumers in a mining and mineral processing operation and can be 80% of total electrical energy consumed at a specific power consumption of around 20kWh/ton.Mill (grinding) Wikipedia,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.

each recognised ore type as coarse particles consume a higher proportion of energy in crushing and grinding. Eliminating the coarse fraction would lead to higher mill throughput particularly for semi-autogenous grinding (SAG) mills. In fact, the coarse pebbles or scats exiting a SAG mill are an indication of this discrepancy10 ORE PROCESSING midasgoldidaho,the ore to a finer size. The term semi rautogenous means that larger ore material fed into the ore processing facility assists the grinding media (steel balls) in reducing the particle size.
