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. Ceramic Grinding Balls

Grinding Media - Union Process

NOTE: Grinding balls and media are sold on a per pound basis, but ATTRITORS and DMQX-Mills are loaded by volume. Therefore, the more dense the media, the more pounds of media required. For instance, a machine requiring only 40 lbs. of stainless steel may require up to 80 lbs. of tungsten carbide.
