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.
