It has been reported that stirred mills consume 30% less energy in coarser fine grinding and approximately 50% in ultra-fine grinding regime (Davey, 2006, Rahal et al., 2011). These factors have led to a steady increase in the number of stirred mill installations in various grinding duties of mineral processing plants.
Vertimill ® (VTM) stirred milling technology has seen increased interest, particularly in cases where a plant needs extra milling capacity or wants to achieve a finer grind. In the past, plants would invest in a second ball mill to run in parallel with their current one to add the additional capacity.
