Energy Use of Fine Grinding in Mineral Processing

The Knelson–Deswik mill is top stirred and can therefore be considered to be similar to an SMD.[5] An important difference among the Isamill, the SMD, and the Knelson–Deswik mill is that of scale. The largest Isamill installed at time of writing had 3 MW of installed power; an 8 MW Isamill is available, but appears not to have yet been ...
