Technical Examples

The rotary disc conveyor system is formed of a series of units or pans linked together to form a continuous conveyor run. Each of the pans preferably includes a pair of rotary discs thereon, with all of the discs of the system rotating simultaneously and unidirectionally to convey material along the conveyor run. Each disc includes a series of generally radially disposed vanes thereon, to assist in sweeping the material along the conveyor. Guides may be installed along either side of the system, between each disc, to facilitate material flow and restrict return flow. Mechanical, hydraulic, or electrical power may be used to provide rotation of the discs. The rotary disc conveyor is particularly well suited for use in longwall coal mining for removing loose coal from the mining head and conveying it along the face of the wall to another transport system for removal from the mine.
