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.
A Vertimill typically operates with a ball charge of approximately 1.8 m to 2.0 m deep. There are two clearly defined zones inside the Vertimill the : grinding zone and classification zonethe . Both zones are shown on Figure 2.
The data also showed that the grinding circuit (with a Vertimill for secondary grinding duty) is more energy efficient than a conventional circuit that has a ball mill for secondary grinding duty..
A pilot test campaign was carried out at Metso's pilot plant facility located in York city, Pennsylvania State, USA, to provide information to scale up the industrial grinding circuit.
The improved grinding energy efficiency of the Vertimill® is due largely to the effect of the vertical arrangement. A horizontal Ball mill relies on the tumbling action of the slurry and media for both impact breakage and attrition grinding. However, impact energy is generally not as efficient as attrition grinding since much of the impact .
Globally recognised as efficient grinding machines, they bring substantial improvement in profitability of concentrators. Up to 40% higher energy efficiency 95% or greater uptime 50% less footprint vs ball mill (In same application) Up to 50% less media consumption < 2 weeks to install < 85 db noise .

The Vertimill has an excellent turndown ratio and can be operated at lower than installed power with less effect on grind efficiency than horizontal ball mills. Feed Flow-Rate - This parameter is.
grinding rather than the conventional ball mill. The implementation of this new circuit design was based on Cannington’s positive experience with Vertimill® technology as well as results from modelling and simulation studies. A number of complete grinding circuit surveys were carried out
