Regrinding and fine grinding technology
vertical pin mills. Media velocities were measured using a light-sheet technique. Figure 1 shows the comparison between the measured and calculated (using CFD) radial-axial fluid velocities. In general, good agreement was obtained, although it was found that numerical solution overpredicted the liquid velocity close to the stirrer shaft.Web

Energy Use of Fine Grinding in Mineral Processing
A Vertimill has been used to grind to sizes below 10 μm. The phenomenon of overgrinding is largely the result of using media that are too large for the product size generated. The smallest ball size typically charged into ball mills and tower mills is ½ inch (12.5 mm), although media diameters as small as 6 mm have been used industrially in ...Web
