ABSTRACT:
A method and apparatus for separating recyclable material from waste material in a material handling system. The material separator comprises a screw conveyor that separates waste material from recyclable material. The screw feeder also feeds the recyclable material into a crusher for pulverization. The waste material bypasses the crusher and is deposited onto a screen for removal into a waste bin. The crusher generally pulverizes the material received by the screw conveyor. However, if uncrushable material is dropped into the crusher assembly, a ballistic part ejector is provided for use with the crusher. The crusher apparatus has a housing and a rotary crusher member. The housing of the crusher apparatus includes convergent walls along one portion to direct ballistic or thrown uncrushable debris in a predetermined direction toward an ejector aperture formed in the housing. A closure member operably obstructs the ejector aperture in the housing. A sensor member is used to sense ballistic or thrown debris within said housing. A motor or other power driven device, responsive to the sensor member, is used for opening the closure member for a predetermined period of time to allow egress of the ballistic or thrown uncrushable debris within the housing.
