  • Effect of Pyrite and Pyrrhotite on the Corrosive Wear

    2020-7-1  The wear increment was greater in the grinding of a quartzite-pyrite mixture (26%) than in the grinding of a quartzite-pyrrhotite or a quartzite-pyrrhotite-pyrite mixture (21% and 22%, respectively). In nitrogen atmosphere, the presence of pyrite in the charge appeared to cause increased ball wear as compared to pyrrhotite due presumably to the ...

  • 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.

  • An investigation of the corrosive wear of steel balls in ...

    Ball mills are common grinding equipment in mineral processing industries. Ball wear results from three mechanisms namely impact, abrasion and corrosion. Of these, the corrosion mechanism is the least investigated, due to its chemical-electrochemical nature. Therefore, the aims of this research were to investigate the grinding chemistry influence (slurry pH, solid percentage, water chemistry ...

    The effect of grinding media composition, mineral type, and slurry environment on the wear rate of various grinding media (balls) are discussed. Sufficient wear data have been obtained and correlated. Modes of wear were determined from examination of the ball surfaces using scanning electron microscopy. Five modes of wear have been identified to be operative under certain slurry conditions
