Metso Outotec Vertimill® - Energy efficient gravity induced mill
Vertimill® is a unique product offered exclusively by Metso Outotec. Grinding efficiency, reduced media consumption, lower installation cost, minimal maintenance, and minimal liner wear make Vertimill® the lowest total cost of ownership in many applications, substantially improving the profitability of concentrators.
Mechanically, Vertimill® is a simple machine with an agitating screw suspended into the grinding chamber, supported by spherical roller bearings and driven by a fixed speed motor through a planetary gearbox.
The capacity of each unit size is relative to the required power input for the intended grind, however, mills have been operated with throughputs exceeding 750 mtph.
Lower capital cost
Vertimill® requires a simple and small foundation, which means less floor space is required. In fact, in the same application a Vertimill® has 50% less footprint than a ball mill.
Lower operating cost
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 required. This also allows for up to 95% or greater uptime for more productivity and profitability.
Versatile applications
Vertimill® has proven to be a versatile tool that exhibits many advantages over traditional ball milling in various applications.
It is capable of handling a wide range of feed sizes typically from 400 to 90 microns.
