The SWECO Vibro-Energy Mill's unique vibratory motion, coupled with the use of cylindrical media, allows a dense packing of the media bed assuring maximum media surface contact and minimum void area when operated under a low energy condition. Feed materials as large as 300 microns can be reduced to sub-micron sizes. In the high …

Critical rotation speed of dry ball-mill was studied by experiments and by numerical simulation using Discrete Element Method (DEM). The results carried out by both methods showed good agreement.

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 mill and the circuit configuration are intrinsic to maximizing …
