A portable screen plant for use with a portable crusher for recycling demolition materials and like work. The plant includes a highway trailer on which is carried an upwardly inclined screen feed conveyor and classifying screens beneath the feed conveyor. The frame is articulated such that its forward end can be raised during screening operation to suspend a magnetic separator at a high elevation over a zone adjacent the discharge end of the screen feed conveyor. During transport, the front frame section and magnetic separator are at a lower elevation to provide adequate height clearance for highway travel. The screen feed conveyor is articulated on the trailer to improve road clearance during transport and afford efficient material flow during operation.
