Abstract
A method for spraying a powdered to granular bulk material is disclosed in which a stream of propellant gas is mixed with the bulk material and the mixture is sprayed by a suitable known spraying device. Unwanted clogging of conduits and wastage of the bulk material are prevented by rerouting the flow of the bulk-material/gas mixture at a point upstream from the spray device whenever it is desired to interrupt spraying. A device for effecting this method is also disclosed.
