Claims

[Scope of utility model registration request]

A relatively large-diameter throat is provided in the side wall opening of the approximately vertical introduction tube filled with powder and granules, protruding in the approximately lateral direction, and the outlet of a relatively small-diameter nozzle is disposed at the inlet opening of the throat. In the device for sending out the powder and granular material in the introduction cylinder through the throat by supplying compressed air, the nozzle is inclined downwardly and the outlet thereof is opened near the inlet of the throat, and the A powder ejector characterized in that the lower part of the flow path in the throat is sloped upward.
