WEBMar 1, 2011 · The classifier consists of eight vanes of height 150 mm flat panels pivoted at top and bottom on a pitch circle diameter of 790 mm. The vane angle, relative to the radial line through the centre of the classifier model can be varied from 0 to 60°. However, in this study the angle was kept constant 30°, a setting typically used in coal mills.
WEBMar 1, 2015 · The most significant difference between the MPS and Emill designs is the grinding mechanism. The MPS mill uses a three rollerrace system instead of the 10 ballrace system deployed in the Emill. The elutriator zone in the MPS mill also appears to be closer to the air classifier entry area.
