Stirred mills for wet grinding liming Outotec

Stirred mills have been proven to provide energy savings when compared with traditional grinding mills. The finer the product required, the more efficient stirred mills will be. The attrition grinding action, vertical arrangement, and the finer media size distribution contribute to make stirred mills energy efficient grinding machines.

Stirred media mills in the mining industry: Material

Jun 01, 2020· Gravity-induced Stirred Mill In these mills, media motion is driven by the rotation of a helical impeller; the speed is not sufficient to fully suspend the media, and so at the top of the helix, the media cascades downwards under gravity; this settling ensures that the media remains in intimate contact for efficient grinding, and leads to a

Stirred Milling Technology A New Concept in Fine Grinding

significantly increasing grinding efficiency. Unlike tumbling mills, where comminution occurs from both impact and attrition grinding, in stirred media mills the particles suffer almost entirely attrition breakage between the beads. (Napier-Munn et al., 2005). In stirred mills there are no free-falling possibilities for grinding media, meaning that
