    Rod Mill Grinding Rods 911Metallurgist. Most operations report that grinding rods are added to the mill two or three times a week. Depending on the media consumption rate, this could cause a wide fluctuation in mill power draw, and operation at least part of the time near the peak of the power versus charge volume curve.

  • Grinding Media Sepor, Inc

    Higher density grinding media generally results in faster grinding in a ball mill. An optimum grinding charge for a ball mill may be experimentally determined, however generally the range is from 20% to 50% of the mill volume, or to the center line. Approximately 30-40% of the ball charge will be void space.
