The objective of the work described in this presentation was to explore Vertimill ultrafine (sub 100 µm) grinding test methodologies at both the lab and pilot scales, compare the scale-up data with operational data from the VTM1250 at Gibraltar Mines and subsequently apply this information to particle sizes down to 80% passing 17 µm.

The VXPmills are designed for fine and ultra fine grinding applications. In practice, the mill performs best when the feed has a normal distribution. However, the mill has been used to preferentially grind the coarser "hump" in bimodal distributions without over grinding the finer part of the distribution.
