Oct 01, 2011 Recently, Clermont et al. (2008) introduced the use of a set of sensors called Sensomag . It is basically a tool that allows simultaneous determination of slurry and media charge positions inside the mill. Using the Sensomag , they investigated the effect that changing the discharge configuration of a 4.8 m diameter ball mill has on power drawn.

Gravity induced stirred mills initiate a ball charge motion via rotational movement of a screw to provide a size reduction mechanism. In contrast, fluidized stirred mills use a rotational movement to fluidize a media slurry mixture, resulting in a size reduction mechanism. The type of Open the catalog to page 2.

Media to media contact for rods mills is linear rather than point to point (as with balls) and are much heavier. The larger feed tends to separate rods at the feed end such that larger particles are preferentially abraded. This leads to a narrower size distribution and significantly less slime compared to ball mills.
