Conveyor for conveying fine material

A conveyor for conveying fine materials, particularly a fine coal conveyor for underground operations, comprising a first conveyor unit comprising a substantially C-shaped housing with a bottom horizontal leg, a vertical leg connecting one end of said horizontal leg and an upper leg extending backwardly from said vertical leg over said horizontal leg, a horizontal section in said housing horizontally movable in a transport direction and a vertical section in said housing vertical leg connected to the opposite end of the horizontal section from the beginning of the transport direction in a position to direct the fine materials received from the horizontal section vertically upwardly, and an upper section extending backwardly from said vertical section over said horizontal section, a second conveyor unit mounted on the horizontal housing leg and located adjacent said first conveyor unit including upper and lower superposed troughs having respective upper and lower conveyor sections running in respective upper and lower troughs, said horizontal section of said first conveyor unit having a reversal end and being disposed to traverse at least a portion of said lower section of said second conveyor in the vicinity of said reversal end and substantially at right angles to the direction of transport on said horizontal section, said horizontal section receiving the fine materials from the lower section and delivering the fine materials to the vertical section for movement thereon, said vertical section having a discharge directed to said upper section.
