Abstract: Separation of mixed materials is accomplished by causing a stream of the materials to fall on an inclined separation ramp, while directing a stream of air onto the ramp. Lower-density materials having higher aerodynamic drag, such as paper scraps, are blown up and over the ramp into a first collection zone, while more dense materials having less aerodynamic drag, such as glass fragments, will tend to descend the ramp and fall into a separate collection zone.
