Effect of coal on the corrosive wear of grinding media

Fine grinding may be required for some coals to remove sulfur and ash or io prepare coal-water slurry. Fine grinding leads to increased ball wear, and its effect on the surface properties of the ground coal becomes of concern. Marked ball wear tests were performed to study the effects of oxygen, pH, the soluble species of coal, and the addition of pyrrhotite on ball wear.
