A comparative study on the effects of dry and wet grinding

01/09/2019· On the other hand, the rate of ball and liner corrosion in the wet grinding is extensively higher than in the dry case,; thus, in processes where there are distinct limits with regard to contamination, the decision for having a wet or dry grinding is significantly challenging. These differences in the grinding process also change the properties of grinding products, which in turn
