ABSTRACT:
A self cleaning conveyor roller for supporting a conveyor media carrying contaminant materials. The conveyor roller consists of a drum defining a support surface, having a generally cylindrical shape, and being adapted to be supported for rotation, for supporting a conveyor media. The conveyor roller has a plurality of abutments on the support surface, raised above the support surface, and defining a series of spaced apart conveyor media support ridges lying on a circular configuration, concentric with the drum. The abutments are arranged in generally chevron shapes, around the drum. During rotation of the conveyor roller the abutments cause any debris or contaminants between the roller and the conveyor media to be guided out of the conveyor system. Also disclosed is a method of cleaning a conveyor roller.
