Grinding Media | Sepor, Inc

Steel balls have a SG of 7.7 and have an average weight/volume of 40 pounds/gallon. 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.
