Grinding and Classifying are essential size reduction processes. The CMS Air Classifier Mill Grinding Zone configuration positions Impact Hammers mounted at the periphery of the Rotor Plate (below the Classifier Wheel), a reversible Multiple Deflector Liner enclosing the Rotor Plate, Hammers and a Deflector Assembly (shroud/baffle style) located above the Impact Rotor. The space between the Classifier Wheel and Deflector Assembly forms the Classification Zone
Air drawn into the mill via the Air Inlet entrains the feed material into an upward flow from below the Rotor Plate, dispersing the feed material to the Grinding Zone, where rotating Impact Hammers deliver high-speed impact, shattering and deflecting particles to the Liner and back to the Hammers. Size reduced particles flow to the Deflector Assembly, which then diverts material to the Classification Zone. Fine particles below the selected cut point will pass through the vanes of the Classifier Wheel to the product-and-air outlet, while coarse particles above the cut point will return to the Grinding Zone for further reduction.
