ABSTRACT:
A cleaning device is provided for use with sizing screens in material reduction apparatus, such as crushers, pulverizers and shredders. The cleaning device automatically clears obstructions from the openings in a screen. The preferred embodiment of the cleaning device includes a rake connected to a carriage assembly. The carriage assembly includes a wheel and rail system. The tines of the rake extend upwards into the openings of the screen. When the wheels move along the rail, the rake tines travel along the openings in the screen, forcing any obstructing material into another portion of the material reduction apparatus. The rake is actuated manually, periodically at predetermined intervals or in response to a sensed reduction in flow.
