Vertimill® is globally recognized as an energy efficient grinding machine. Through a low total cost of ownership, they bring substantial improvement to the profitability of concentrators. During the years, Vertimill® technology has proven to be efficient especially in secondary and tertiary grinding, regrinding, fine grinding, and lime slaking applications.
Vertimill® is a unique product offered exclusively by Metso. Grind 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 500 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.
