effect of stirrer speed on product size vertical stirred mill:

Stirred Mill - an overview | ScienceDirect Topics

In high-speed stirred mills the effect of mill tip speed, media size and density can be evaluated simultaneously using the grinding media 'stress intensity' approach and an illustration of this is summarised in Fig. 1.5 which shows a plot of product particles size (starting size 45 μm, product size ∼2–6 μm) versus stress intensity for a ...

Media stress intensity analysis for vertical stirred mills

Stress imposed on particles is result of the centrifugal forces of grinding media being agitated at high speed. In this situation stress intensity is proportional to the cub of media size, stirrer speed velocity squared and the difference between the media and slurry density (Kwade, 1996). In low speed vertical stirred mills (LSV) such as the ...
