VXPmill for fine & ultra fine grinding | FL

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.
