ABSTRACT:
A method and an apparatus for powder spraying can be used, for example, for electrostatic enameling. In order to achieve an easily regulatable high powder output rate, it is proposed to fluidize powder in a closed container, extract it in the region of the fluid bed and cause it to emerge through a nozzle on the container. The container is subdivided by a frit into a first chamber to which air is fed and a second chamber which contains the powder and out of which air is discharged through a valve. A powder output rate can be regulated by the regulation of air pressures.
