  • Optimizing your SAG mill operationInternational Mining

    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.

    Jan 01 2016 · Ferro-silicon media may be prepared by grinding it in a ball-mill or by atomization of the molten material. The atomized variety has a more spherical shape which allows a higher medium density to be obtained (up to 3.4) and a lower apparent viscosity than the more angular particles. The spherical particles are also more chemically stable.

    If the peripheral speed of the mill is too great it begins to act like a centrifuge and the balls do not fall back but stay on the perimeter of the mill. The point where the mill becomes a centrifuge is called the "Critical Speed" and ball mills usually operate at 65 to 75 of the critical speed.
