Stirred media mills in the mining industry: Material grindability
Rather than using a lab scale Vertimill, which suffers from scaling problems, this test utilises a lab scale ball mill that is smaller than in the Bond and Levin tests, and uses 19 mm media (typical of industrial Vertimills) [8], to carry out a series of batch grinds on the feed material at different energy inputs. This allows for better ...
