ABSTRACT:
A multi-fingered clamshell disc is taught that is used with an apparatus for classifying a stream of mixed recyclable materials. The disc includes a body with outwardly extending fingers, a centrally located square opening, a tapered notch and a tapered slot, with the notch and slot on opposite sides of the square opening. Insert sets are molded within the body adjacent to the notch and the slot configured to receive socket head cap screws that compress the notch and slot thereby tightly gripping the shaft of the apparatus. The disc is installed by spreading open the body in clamshell manner then slipping the body over the shaft allowing it to spring back in shape then attaching with the cap screws. A spacer is installed on one side or both sides of the body for separating the disc from other discs.
