A portable recycle crusher system has a hopper with inward and downward sloping sides, and fold-out hopper extensions. A belt feeder beneath the hopper slides on a slide deck made of a low friction, wear-resistant plastic bolted to a steel plate to prevent tearing of the belt when sharp pointed objects are dumped into the hopper. Stopping and starting and speed of the belt are controlled by remote radio control. Materials fall off the end of the belt feeder onto vibrating screen, which allows fine materials to bypass a crusher. The materials then enter a large rectangular opening of the crusher, and approach rotating hammers at a proper angle and speed. The hammers strike and break the materials and throw them against abrasion-resistant plates. The broken materials fall between the spinning hammers and through sizing screen steel grates, which provide positive product size control. The materials fall onto a discharge conveyor, which carries the materials away from the recycle crusher and to a delivery conveyor. The hopper, conveyors, crusher and scalper are mounted on a rectangular beam frame, which is supplied with an axle and wheels and a connector for towing the crusher system on roads. An engine mounted on the frame drives a hydraulic pump to operate the feeder and conveyor, and mechanically drives the crusher. The entire apparatus is mounted on an over-the-road trailer for towing to a road resurfacing location.
