A system for conveying particulate material from a first location to a second location. The system includes an auger rotatably disposed in a cylindrical auger chamber having a discharge end coupled to an inwardly-tapering nose cone. The nose is attachable to an elongate conveying conduit for conveying the particulate material. First and second plenum chambers co-act to inject concentric annular waves of pressurized fluid into the nose cone at an entry point adjacent to the discharge end of the nose cone. The arrangement provides a substantially laminar gas layer which lines the interior surface of the conveying conduit and circumscribes a flowing stream of gas and particulate material to thereby minimize contact of the particulate material with the interior surface of the conveying conduit.

[ What is claimed is:] [1.] A system for conveying particulate material from a first location to a second location, the system comprising:a mixing chamber having a first opening and an opposing second opening;moving means disposed in communication with the mixing chamber for receiving particulate material at a first location and moving said particulate material away from said first location and into the mixing chamber;first injection means concentrically surrounding the moving means and being disposed in communication with the first opening of the mixing chamber for injecting a first annular wave of pressurized fluid therein;second injection means concentrically surrounding at least a portion of the first injection means and being disposed in communication with the first opening of the mixing chamber for injecting a second annular wave of pressurized fluid therein, such that the first and second annular waves of pressurized fluid co-act with the moving means to cause the particulate material to be transported through the mixing chamber to a second location.
