2.2. Grinding Test. In this paper, the wet ball milling process was used in the laboratory ball milling test. Before grinding, the ball mill was kept idle for 10 minutes and then washed together with the grinding media. Three types of ores were crushed and separated by a jaw crusher, and the ground particle size of -2 mm was selected.
Other investigators have observed similar behaviour. For example, Gates et al. (2008) have used ball mill abrasion tests (BMAT) to predict the relative service lives of wear-resistant alloys for grinding media in mineral grinding environments. The results showed that very hard (above 630 HV) martensitic steels and white cast irons only offer ...
