Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of …

The Vertimill® is a vertical stirred mill that uses a helical screw to impart motion in the charge. 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.

When the static ball charge level has risen by 300 mm (1 foot), it is an indication of a worn screw liner and a liner inspection/change is recommended. This is applicable only for mills operated with a constant power draw. After any liner change, a new initial ball charge should be measured/recorded, followed by a repeat of the above …
