The Vertimill™ efficiency factor could be backcalculate from pilot or industrial circuits using commercial software, but this procedure was avoided because the main idea of the methodology presented in this investigation is perform the vertical stirred mill scaleup from laboratory tests. The factor of is derived off standard vendor ...

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 ...

Vertical stirred mills have been widely applied in the minerals industry, due to its greater efficiency in comparison with conventional tumbling mills. In this context, the agitator liner wear plays an important role in maintenance planning and operational costs. In this paper, we use the discrete element method (DEM) wear simulation to evaluate the screw liner wear. Three different mill ...
