Vertimill® - Metso Outotec

Vertimill® is an energy efficient grinding machine. They tend to grind more efficiently than, for example, ball mills with feeds as coarse as 6 mm to products finer than 20 microns. This provides up to a 40% higher energy efficiency. With the Vertimill® simple and robust design, limited liner replacement is
