Abstract: A conveyor system may include a pipe conveyor with a head end, a tail end, and an inclined section. The conveyor system may also include a conveyor belt comprising a first portion and a second portion, and the conveyor belt may be configured to form a pipe shape when the first and second portions of the conveyor belt are overlapped. In some embodiments, the first portion may include a first type of longitudinal reinforcement elements and the second portion may not include any of the first type of longitudinal reinforcement elements. In some embodiments, the conveyor system may include a material plug configured to circumferentially engage at least a portion of an internal surface of the conveyor belt.

Abstract: An angle pipe conveyor comprises a conveyor belt or roller belt. The conveyor belt includes a first conveyor belt section and a second conveyor belt section to define a cylinder structure having an overlap thickness based on plural sections of the roller belt with an overlap structure having an oval- shaped cross section. Support elements support the conveyor belt as rollers located on the support elements guide the cylinder structure.

Abstract: A pipe conveyor may include a conveyor belt formed into a pipe-like shape to define a space that contains material to be transported by the conveyor. Along at least a portion of the pipe conveyor, friction drive conveyors or friction tires may be positioned. The friction drive conveyors may include friction drive belts that engage the pipe conveyor belt. Via this engagement, the friction drive conveyors apply a force to the conveyor belt that moves the conveyor belt in a desired direction. Further, when the friction drive conveyors or friction tires are positioned within an inclined vertical section of the conveyor belt, the friction drive conveyors or friction tires vertically lift the pipe conveyor belt via pushing the conveyor belt in a vertical direction, thus assisting a drive pulley that vertically pulls the conveyor belt and material transported on the conveyor belt from a lower elevation to a higher elevation.
