    Stirred Milling Technology – A New Concept in Fine Grinding

    classification. With the grinding media evenly distributed, the ore particles remain in constant contact, 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.
