  • 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.
