The vertical stirred mills have a screw agitator centrally located in the mill chamber, which promotes the grinding action by stirring the media and circulating it throughout the mill (Morrison et al., 2009). Stirred mills can be divided into two classes: those with low agitator speeds, that also use gravity to promote media movement and apply ...
