How to Reduce Steel Consumption in Grinding Mills

It is difficult to explain the large increase in the rate of metal loss in wet grinding unless some mechanism other than abrasion is involved in the grinding process. Hence, the mechanism to account for the large increase in metal loss with wet grinding systems is almost certainly corrosion. ... The contribution of corrosion wear to overall ...
