May 9, 2000 . “stirred ball mill.” There are quite a few types of Attritors; we can categorize them as dry grind. Attritors, wet grind Attritors, regular speed Attritors, and high speed Attritors. A useful and simple equation describing the grinding momentum is M x V (mass x velocity), which enables us to see how the Attritor fits.
equation will be used for the estimation of breakage rates without imposing any functional form. .. FIGURE 3. Time dependence of breakage rate for a line dry-grinding experiment. (coarse-size feed). Wet Grinding Results. In general, wet ball milling gives higher mill capacities than dry grinding, providing the slurry.
