ABSTRACT:
Disclosed is a pneumatic conveyor system for powder. The conveyor system includes a powder feeder, a bent pipe, a transport pipe, a first air supply nozzle connected to an upper pipe member of the bent pipe, and a second air supply nozzle connected to a curved pipe member of the bent pipe oppositely to the lower end opening of a converging pipe portion of the curved pipe member. Alternate supply of air from the first and second air supply nozzles to the bent pipe is effected intermittently at a predetermined interval of time, so that the power is compacted and formed into a lump of clean powder plug.
