Stirred media mills are relatively new to mining industry, and several new technologies have been developed such as the VXPmill (vertical stirred mill). There is little technical understanding of optimizing and scaling-up of the VXPmill. This thesis addresses both of these issues and therefore supports commercial applications of this vertical stirred mill. Stirred media mills are …...Stirred Mill. In stirred mills, the mill shell is stationary mounted either horizontally or vertically and motion is imparted to the charge by the movement of an internal stirrer.
