There is a large gap between the tip speed and power intensity of the low-speed vertical mills and the high-speed horizontal mills. The VXP mill bridges the gap between high-speed and low-speed mills. The VXPmills are designed for fine and ultra fine grinding applications. In practice, the mill performs best when the feed has a normal distribution.
