LAMINAR MATERIAL SORTING APPARATUS

摘要

A material sorting apparatus includes a perforated screen adapted to be moved around an endless track. Devices suck air through the screen inwardly of the track in a predetermined area thereof. A material to be sorted is supplied to the apparatus such that it falls under gravity so that laminar material is selectively sucked towards the surface of the screen. This material is transported in contact with the screen while the screen is moving through and out of the predetermined area but is released from the suction forces when the screen moves out of the predetermined area. A first collection region is located beneath a region adjacent the predetermined region of the track. A second collection region is located adjacent an area of the track to receive material which has been transported in contact with the screen out of the predetermined area of the track.
