### Grinding Circuit an overview ScienceDirect Topics

The circuit comprises a SAG mill, 12 m diameter by 6.1 m length (belly inside liners, the effective grinding volume), two pebble crushers, and two ball mills in parallel closed with cyclones. The SAG mill is fitted with a 20 MW gearless drive motor with bi-directional rotational capacity.

SAG Mill Circuit Example — Gold Processing SAG mill circuit example for gold processing [image: (135-6-3)] AG/SAG Mill. AG/SAG mills are normally used to grind run-off-mine ore or primary crusher product. Wet grinding in an AG/SAG mill is accomplished in a slurry of 50 to 80 percent solids. 2D and 3D simulations of particles in a SAG Mill

Prater’s Air Classifying Mills operates by using the combination of two-stage closed circuit grinding/milling with an interstage air classifier all in one convenient unit. The internal air classifier continuously recirculates particles that are larger than desired back into the grinding zone ensuring an optimal final product particle size.
