ABSTRACT:
The sorting apparatus contains a rotor equipped with blades or vanes which move along a screen or sieve located beneath the rotor. The screen forms a partial surface of a body of revolution, such as a partial surface or section of a cylinder. The fiber stock mass which has not moved through the screen is upwardly propelled into a turbulence chamber or space by the action of the rotor and again falls back onto such rotor or another rotor. A domed guide surface serves to guide the fiber stock mass.
