Exploring ball size distribution in coal grinding mills ...

The amount and ball size distribution in this charge, as well as the frequency with which new balls are added to the mill, have significant effects on the mill capacity and the milling efficiency. Small balls are effective in grinding fine particles in the load, whereas large balls are required to deal with large particles of coal or stone contaminant. The steady state ball size distribution in the mill depends on the top-up …

Exploring ball size distribution in coal grinding mills ...

01/05/2014· 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 …
