ABSTRACT:
A system for conveying liquid or particulate material from a first location to a second location. The system is utilized in combination with an elongate barrel having a discharge end. A plenum chamber is placed around the barrel. A frustoconical air reduction cone is contained within the plenum chamber. The reduction cone has a narrower open end which is coupled to an interior front wall of the plenum chamber so as to surround the auger barrel. The narrower open end surrounds and communicates with a port in the front wall through which the auger barrel extends. The port and the auger barrel thus form an annular constriction therebetween. Pressurized air is injected into the plenum chamber which is drawn into the cone and passes through the annular constriction in the form of a continuous annular stream of pressurized air enveloping the discharge end of the barrel. The stream of air carries any material discharged from the barrel along a movement path.
