Regarding stirred mills, the two issues you haven't touched on are they can be a pain in the butt to do maintenance on (you have to dump the mill contents of the floor which you don't do with a tumbling mill) and sometimes they have issues with the top size of material that comes from upstream stages (you need to match the media size in a stirred mill its feed top size).

Gravity-induced Stirred Mill – In these mills, media motion is driven by the rotation of a helical impeller; the speed is not sufficient to fully suspend the media, and so at the top of the helix, the media cascades downwards under gravity; this settling ensures that the media remains in intimate contact for efficient grinding, and leads to a ...

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.

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

Vertical stirred mills have been widely applied in the minerals industry, due to its greater efficiency in comparison with conventional tumbling mills. In this context, the agitator liner wear plays an important role in maintenance planning and operational costs. In this paper, we use the discrete element method (DEM) wear simulation to evaluate the screw liner wear.
