  • Exploring ball size distribution in coal grinding mills

     · It has been shown that mill capacity is linearly correlated to media surface area thus using 30 mm balls as top size which leads to a fine ball size distribution in the mill is evidently a better approach than the current approach of using larger ball sizes. However the fact that the coal feed to this plant is known to be contaminated with a small fraction of hard-to-grind stone which will strongly impact on
