Jan 01, 2016 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.

Comparison of energy efficiency between ball mills and

Jun 01, 2009 The work using a vertical shaft stirred mill compared with Bond ball mill, both operated in closed circuit with a classifier, demonstrated a clear trend that on average 30% energy saving can be expected by using the stirred mill to replace ball mill for coarse grinding from a top particle size 3.35 mm to P 80 less than 100 μm.
