Claims

[Scope of utility model registration request]

A throat with a relatively large diameter is provided in the side wall opening of the introduction cylinder filled with powder and granules, and a relatively large diameter nozzle is provided parallel to the inlet opening of the throat, and compressed air is supplied to the nozzle. 1. A powder ejector for sending out powder and granular material in the introduction cylinder by supplying the powder and granular material, characterized in that the axis of the nozzle is eccentric below the axis of the throat.
