  • Patent number: 10011431
    Abstract: A long run conveyor system is disclosed in which at least a portion thereof traverses a slope sufficiently steep so that tensile force associated with overcoming the effects of the slope is greater per unit length than tensile force per unit length of run due to main frictional resistance of the conveyor system. The long run conveyor system includes an external belt defining a continuous loop traversing an entire route of the conveyor system and is configured to transport material load across the entire route. The conveyor system also includes an internal belt positioned inside the continuous loop of the external belt, which also traverses substantially the entire route. An upper side of the internal belt operably engages an underside of the external belt. The internal and external belts are configured such that each respectively carries an approximately equal amount of belt tension.

  • Patent number: 9573765
    Abstract: A belt-conveying installation has at least one carrying structure, a conveying belt and at least one drive apparatus for driving the conveying belt. The drive apparatus includes at least one drive shaft, at least one drive-shaft-bearing arrangement, at least one drive roller and at least one independently excited drive motor in the form of a frequency-converter-fed alternating-current synchronous motor with a stator and a rotor. The drive shaft and the at least one drive motor are connected to one another without any gearing, and the rotor and drive shaft are arranged coaxially, each drive shaft being guided through at least one rotor. The belt-conveying installation can be operated and used for heavy industry, in particular for the extractive or mining industry.

  • Publication number: 20160332822
    Abstract: A conveyor system, at least a portion of which may traverse a continuous slope sufficiently steep such that tensile forces associated with overcoming the effects of the slope are several times larger per unit length of run than tensile forces per unit length of run due to main frictional resistance of the conveyor system, may include a belt-on-belt drive. The belt-on-belt drive may include an internal belt configured to operably engage the carry belt of the conveyor system so as to share the tension load with the carry belt.

  • Patent number: 9145261
    Abstract: A conveyor system for an open pit mine may include one or more conveyor lines. The conveyor lines are used to transport material from one location in the mine to another location. The material transported may be a waste material, such as overburden material, or coal. The conveyor lines may move from a first end of the pit to a distal second end. When the conveyor lines reach the second end, they may reverse direction and return towards the first end. During this reversal in direction of travel, equipment may be selectively swapped between the conveyor lines. The conveyor lines may include at least one mobile bridge conveyor. Each mobile bridge conveyor may support one or more conveyors that transport the material.

  • Publication number: 20120061211
    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.

  • Publication number: 20120061212
    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.

  • Publication number: 20110226591
    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.
