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.
Grinding particles below 75 m with the ball mill causes energy costs to rise exponentially, and a P 80 of 45-40 m is considered to be the final practical limit of product size from the ball ...

Vertimill liner lifting tool Metso Vertimill screw liners can be fitted with unique lifting fixtures to maintain a solid hold and stable center of gravity for ease of transport. Liner lifting holes are used for a safe two point attachment to the tool during installation and removal.
The balls become coated and the grinding efficiency decreases. The pilot mill is also equipped with a sensor measuring the ball and pulp toe and shoulder angles see Figure 3. These data are then used to calculate the total pulp and ball charge angle see Graph 5. Graph 5 clearly illustrates how the ball charge stays quite
Oct 01, 2020 Oct 01, 2020 In fact, in the same application a Vertimill has 50 less footprint than a ball mill. 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.
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 ...

Allen also successfully fit the model to a pilot and full scale VertiMill, however the model required some re-tuning for each new dataset. ... the grinding zone and also effects the fluidisation and power draw of the mill. With smaller mills

The ... operation including gravity induced stirred mills such as the Metso Vertimill and the Nippon Eirich ... there is an internal classification effect that is previously mentioned in several publications but was not quantified through experiments ...
The active grinding volume in a stirred mill was first determined by simulation and later investigated by measurements. Grinding is a consequence of the velocity gradient between the grinding media and the particles in the slurry which generate stress events. The different gray
