Vertimill and Stirred media detritor
The figure to the left shows the typical application ranges for ball mills and stirred mill. The Vertimill is always more efficient than a ball mill with energy savings ranging from 30% to greater than 50%. The transition point from the Vertimill to an SMD varies depending on the ore properties but generally is in the range of 20 to 40 microns.
Regrinding and fine grinding technology
The fundamentals of fine grinding were established by Profesor Klaus Schonert in the 1980s and the fundamentals of stirred milling where developed in the 1980s and 1990s by German researchers, Steier, Schwedes, Stehr, Kwade and others. This work led to the development of a new generation of stirred mills capable of grinding finer and finer.
