Abstract: A conveyor assembly having a conveying member made substantially of ultra-high-molecular-weight polyethylene material. The conveying member can be provided with a support structure for supporting the conveying member. At least one biasing member and at least one securing member can be used to secure the conveying member to the support structure. The biasing member and the securing member, along with the support structure, form an arrangement which can allow the conveying device to accommodate the growths and deformities of the conveying member.

Abstract: A conveyor for materials uses a gearset to generate horizontal differential conveying motion in a conveying member. The conveying motion includes an advancing stroke in a conveying direction and a retracting stroke in a direction opposite to the conveying direction. The linear velocity of the retracting stroke is greater than the linear velocity of the advancing stroke to move materials along the conveying member in the conveying direction. The gearset is preferably a ring gear and a pinion.

Abstract: Conveying apparatus and methods employ a continuously vibrating element and a plurality of longitudinally aligned, overlapping, inclined conveyor pans, each of which has its own independently operable discharge gate. Material may be moved by the conveyor from a source to one or more material discharge destinations by selectively coupling and uncoupling predetermined conveyor pans to the continuously vibrating element. When not coupled to the continuously vibrating element, the conveyor pans are at rest in motionless isolation from the pans that are vibrating.
