Stirred Milling Technology – A New Concept in Fine Grinding

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. (NapierMunn et al., 2005). In stirred mills there are no freefalling possibilities for grinding media, meaning that impact action does not occur. The bead size is small, typically 1 to 6 mm which means a ...

Stirred Media Grinding Mill

Stirred Media Grinding Mill. Stirred mills have been proven to provide energy savings compared with traditional ball mills. the finer the product required, the more efficient stirred mills will be than a ball mill. the attrition grinding action, vertical arrangement, and the finer media size distribution contribute to make stirred mills more energy efficient grinding machines.

Using stirred media mills in ore grinding

· In stirred media milling, a smaller grinding media size compared to a conventional ball mill makes highspeed movement possible, thus higher force on the ore particles trapped in media is applied. This is significant since as the particle size becomes smaller, the force needed to break the particles increases. Different types of high speed stirred mills have been developed in the mining ...
