ABSTRACT:
A sorting conveyor is shown and described for moving composite material through the output gate of a bin and then past a sorting station to remove unwanted elements of the composite material. At the interior side of the output gate rests a powered leveling roll rotatable about an axis transverse to the material flow for maintaining a selected volume of composite material exiting the bin. An upward and forward facing portion of the powered leveling roll is shielded against contact with the composite material in the bin. A downward and rearward facing portion of the powered leveling roll, including the portion opposing the conveyor, moves opposite the direction of material flow. The powered leveling roll includes formations for engaging the composite material and repelling excess material. The powered leveling roll thereby keeps the output gate from jamming, provides a metering function for controlling the amount of material flow released from the bin, and maintains a desirable cyclic flow of material within the bin to avoid bridging.
