• The Vertimill is a unique product offered exclusively by that has a long history in the metallic mining industry. Mechanically, the Vertimill is a very 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.

In comparison to traditional ball mills, in fine and regrind applications, the VERTIMILL ® mills can perform the same grind with 30 % to 50 % less energy and significantly lower grinding media consumption. The VERTIMILL ® application range is also being extended into the coarse and secondary applications, creating more energy saving ...

Vertimills can be either top fed (the new feed is introduced into the top of the mill via a feed pipe that deposits the feed just above the grinding media), or bottom fed. In the case of Minas Rio, the cyclone underflow is fed by gravity into the bottom of the Vertimills.

Vertimill technology is part of Outotec's Planet Positive offering, providing the lowest total cost of ownership compared with other grinding mills in many applications thanks to its high energy efficiency, reduced media consumption, low installation cost as well as minimal liner wear and maintenance, the company claims.
