• Optimizing your SAG mill operation

    In multi-stage ABC/SABC circuits, the AG or SAG mills are in closed circuit with screens and pebble crushers The mill discharge from these mills consists of slurry, which goes to the ball mills for further grinding, and coarse pebbles/rocks, which are crushed and sent back to the mill.
