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.
Jul 01, 2007 the slurry density or pulp percentage of solids and the size of the grinding media are often considered for ball mill optimization. laboratory grinding tests were conducted to identify possible interactions between the two variables and the fineness of the ground.
