A compound disc is used to eliminate a secondary slot normally formed between the outside perimeter of discs on adjacent shafts of a material separation screen. The compound disc includes a primary disc joined to an associated secondary disc. The primary disc and the secondary disc each have the same shape but the secondary disc has a smaller outside perimeter and is wider. The primary disc and associated secondary disc are formed from a unitary piece of rubber. The compound discs are interleaved with oppositely aligned compound discs on adjacent shafts. In other words, the large disc is positioned laterally on a shaft to longitudinally align with a smaller disc on an adjacent shaft. The oppositely aligned and alternating arrangement between the large discs and small discs eliminate the secondary slot that normally exists in disc screens.

A system for classifying recycled debris comprising ferrous materials, fines, non-ferrous light material and non-ferrous heavy material. The classification system is made of a hopper having an inlet, including a spillway opening defining a lowermost portion of the hopper inlet, and an outlet formed along a lower portion of the hopper and contained in a plane at an angle of about 50 degrees from horizontal. A conveyor covering the outlet includes substantially rigid cleats extending into the hopper for agitating the debris and for transporting heavy material, such as glass bottles, out of the hopper outlet. Agitation of the debris causes the heavy material to drift to the lower portion of the hopper and the light material to rise to the top portion and flow over the spillway. A second conveyor positioned beneath the spillway catches the light material and carries it to another location.

System and method for separating recycled debris

A conveyor with elongate side members with each member being of irregular shape in section. An inclined surface of each side member partially supports an endless conveyor belt with a mid-portion of the belt supported at intervals by fixed conveyor crossmembers. The crossmembers are molded from material having a low coefficient of friction to adequately support the belt and loads thereon while serving to rigidly interconnect the side members of the conveyor. Fastener assemblies extending through the crossmember ends and abutting portions of the side members couple same yet permit convenient crossmember replacement. Drive means powers a conveyor pulley. Top and bottom covers confine airborne dust particles.
