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.
Details 
Stirred mills can be divided into two classes: those with low agitator speeds, that also use gravity to promote media movement and apply forces, and those with high agitator speeds, with the speed of the agitator used to effectively fluidize the media (Wills and Finch, 2016, Lichter and Davey, 2006). The subject of this paper is the Vertimill ...

Note that the hardness of these scats is not measured by a Bond BWi because that test crushes everything to minus 3.35 mm, the maximum size for good ball milling or VERTIMILL efficiency. I do agree that the VERTIMILL power will be lower than a ball mill so there is merit in replacing ball mills with Vertical Stirred mills.
