Stirred Mills – Ultrafine Grinding - ScienceDirect

Vertical stirred mills are usually charged with media occupying 80% of the mill volume which is in sharp contrast to tumbling mills that are seldom charged more than 40% of their volumes to allow space for the tumbling action to develop. The stirred mills are charged with a media size of 10–12 mm and operated at a maximum tip speed of 3–8 m/s.

Media stress intensity analysis for vertical stirred mills

Media stress intensity analysis developed for high-speed horizontal mills was modified to include the effect of gravitational force in the vertical stirred mills such as the Tower and SAM units. The results suggest that this approach can be successfully applied for both mill types. For a given specific energy input, an optimum stress intensiO ...
