  Corrosive Wear of Grinding Media in Grinding a Complex …

  Addition of sodium nitrite-borax, sodium hydroxide, sodIUm carbonate, lime, or sodium silicate reduced wear of forged steel balls and cast iron slugs in wet grinding a complex zinc-lead-copper sulphide ore in laboratory ball mills. Maximum wear reductions were 27 per cent (forged steel balls) and 33 per cent (cast iron slugs) with sodium hydroxide and nitrite …

  Nature of corrosive and abrasive wear in ball mill grinding

  198841 · Abstract. Laboratory results of marked-ball wear tests are used to discuss the relative significance of corrosive and abrasive wear in wet grinding. The electrochemical mechanism was investigated by correlating the corrosive wear with the corrosion current obtained from polarization curves under abrasion. Slurry rheology governs the manner in ...

  Influence of pyrrhotite on the corrosive wear of grinding …

  In the absence of sulfide-bearing minerals such as pyrrhotite, corrosive wear of the grinding balls in the wet grinding of magnetite ore was relatively small, even in the presence of oxygen. The presence of pyrrhotite significantly increased the corrosive wear of mild steel and HCLA steel balls, especially in the presence of oxygen.
