Jul 03 2017 Selection of Volume of Ball Loads in Continuous Dry Open Circuit Grinding The tests reported in tables 19 and 20 were made in cooperation with a large cement-manufacturing company that wished to obtain more grinding for the power expended. The ball load in its clinker- grinding mills was 18 percent of the mill volume and the company did not deem it consistent to increase the ball load because the mills having been pebble mills originally could not carry a heavier load; also the ball .
Oct 19 2017 There is a mathematical solution to this problem – the Bond formula. It uses to help determine the grinding media optimal size must be loaded into the ball mill for proper operation ensure. The calculation formula is below B – the grinding balls diameter mm; A – the correction factor for grinding balls A 2017; for cilpence A 1815;
