Evaluation of grinding media wear-rate by a combined ...

15-3-2015· Wear-rates of different grinding media are determined by two commonly used methods of self-wear in water and grinding with mineral slurry. After the analysis of all results, we design an improved testing method on wear-rate, which combines the fast process of defects formation when grinding with mineral slurry with the fast process of surface collapses of self-wear in water.
