Vertimill VS Ball Mill (14 replies) Paul Morrow. 4 years ago. ... To get energy efficient grinding below approx. 40 µm you need to have finer grinding balls than are suitable for the tumbling mill. So, the case for the stirred media mill that often has media in the range 5-10 mm if used as a tertiary grinding step or for re-grinding.
circumstances stirred milling is significantly more efficient than ball milling. As a case in point, the VERTIMILL® grinding mill has been cited in a couple of papers (Nesset et al., 2006; Mazzinghy et al., 2012) as being some 35% to 40% more efficient than ball mills for fine grinding .
