optimum stirred milling solution for different concentrator applications. These methods and strategies will focus specifically on the two major stirred mill machine types; namely, gravity-induced (VERTIMILL™ grinding mill and Nippion-Eirich tower mill) and fluidized (SMD, Isamill™, Knelson-Deswik mill, etc. ).

Stirred mill technology dates back to 1928 where the idea to use "an agitator and spherical grinding media" was presented. The year 1948 saw the successful application of DuPont's "sand mill" for pigment grinding. Subsequent years have led to the development of different types of stirred mills spanning

The horizontal stirred mill approach for grinding rocks, minerals, and industrial materials was developed in Australia, where it has been used for a number of years. Conventional ball mills rotate the mill body (a horizontal cylinder), tumbling both rock and metallic balls. Stirred mills use an internal auger to agitate the feedstock (ore which ...

STIRRED MILLING TECHNOLOGY Mill structure The vertical stirred media grinding mill uses a grinding chamber filled with small beads whereby comminution takes place by attrition between the beads. The stirring effect is caused by rotating discs mounted on a shaft. There are also stationary discs on the mill body positioned in between each
