ABSTRACT:
An improved nozzle for unloading dry bulk particulate material by suction through the nozzle. A transport medium such as air is drawn by the suction to mix with and thus fluidize the material so that the material may be drawn up through the nozzle. The nozzle is tapered at its first or intake end to cut down on dust emission. The nozzle is of substantially constant internal cross sectional area between its first and second ends to provide the most efficient operation. The nozzle is self regulating in that the suction together with the volume of dry bulk particulate material determine the amount of air needed to fluidize and transport the material.
