mill selection is widely used. When high capacity ball mills were installed from the late 1970s (5.5 m diameter and larger) it was found that throughput predictions for large mills with high feed rates of coarser particles were greater than those achieved. Correction factors based on the new data were required. SAG

Recycle pebble crushing is widely deployed in autogenous grinding (AG) and semi-autogenous grinding (SAG) mill circuits. The application of pebble crushers can significantly boost circuit throughput by reducing critical size pebbles that potentially cause a bottle-neck in a primary grinding operation. Previous research shows that by controlling the cone …
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%.[6][7] The largest SAG mill is 42′ (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.[8]
