Abstract

The wind sifter housing has feed inlet and prod. outlet, fixed rim blades and an inside power driven rotor in a cylindrical bladed section, with the sifting air fed to the blades through a tangential housing entry. The rotor is fitted with at least two concentric rings of blades (14,15;16,17) together with guide blades (14',15';16',17'), all with separate submounted end prod. outlets for discharge through a separate outlet (8). The rotor blade rings are pref. rigidly interconnected, or can rotate independently at dissimilar speeds.
