ABSTRACT:
A device for loading a stream of air with a controllable amount of granular or powdery material includes a container for the material. An annular conduit disposed in the free space above the material in the container has nozzles which are operable to discharge compressed air into the container to blow and churn-up the material. A double tube vertically and slidably mounted on the cover of the container is operable to conduct the compressed air to the annular conduit and to receive the air laden with material which has been blown and churned-up by the compressed air discharged into the container by the nozzles on the annular conduit.
