A conveyor pulley design incorporates a plow design that forces tramp material away from the belt and discharges material down and away from the belt, bearings, take-up assembly, maintenance equipment and personnel. The pulley uses a modular construction that allows for optimized manufacture and inventory processes and reduces the materials cost in the pulley

A self cleaning apparatus for a belt conveyor. The self cleaning apparatus comprises a rotor positioned adjacent to an outer side edge of the return conveyor portion of the belt, and a rotor housing received about the rotor. The rotor housing has an intake and a discharge, with the intake receiving and directing material on the upper surface of the return conveyor portion to the rotor as the belt rotates. Rotation of the rotor causes the directed material to be propelled by the rotor through the discharge and to be deposited onto the upper surface of the loaded conveyor portion.

A clean-out roller that interfaces with a conveyor belt is provided. The roller includes a first sprocket adjacent a first end, a second sprocket adjacent a second end, and a plurality of paddles arranged widthwise from the first end to the second end. The plurality of paddles are coupled to the first sprocket and the second sprocket and located circumferentially around the sprockets in an unequal spacing pattern about the sprockets. A paddle of the plurality of paddles including a tip edge extending radially outward to extend into openings of the conveyor belt.
