Agitated media mills stir the grinding media to break down the target material into ultra-fine particles. The grinding media generally consists of spherical metallic or ceramic beads that are stirred into action by the agitator. Agitated media mills are designed in both vertical and horizontal configurations.
In Mineral Processing Design and Operations (Second Edition), 2016. 10.2.4 Operation of Vertical Mills. 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 …
Vertical stirred mill scale-up and simulation: Model. 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).
