The relationship between the available volume for slurry and the VertiMill® power is shown in Fig. 1.The relationship as shown in the figure was validated by survey data collected from a mine site (Palaniandy, 2014) where the entire mill grinding media was weighed after a crash stop.The survey data showed good agreement with the developed model.
Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of a mill's energy budget. Overall …
