Exploring ball size distribution in coal grinding mills
网页2014年5月1日Tube mills use steel balls as grinding media. Due to wear in the abrasive environment it is necessary to charge new balls periodically to maintain a steady balanced ball charge in the mill. 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

Grinding Balls and Other Grinding Media: Key
网页2021年1月25日The normal top size of media used is 10-25mm, but even smaller grinding balls can be used for very fine grinding. Isa Mills: <0.1” grinding balls are recommended. The Isa Mill is more efficient when using small media (i.e. high-chrome steel balls). Rotary Mills: Small cylpebs (<1”) are effective in ultra-fine wet regrinding operations.
