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 ...
