ABSTRACT:
An apparatus and a method destined for the production of metal powder, wherein inert gas, especially argon is admixed to a metal melt rising in a riser, thereby forming a metal froth which is pressurized likewise by inert gas, especially argon of high pressure in a pulverization chamber, at the same time, forming metal droplets. These are displaced from the pulverization chamber by the gas blown into the same, to enter an expansion chamber in the form of a collecting vessel, the metal droplets being accelerated in the passage from the pulverization chamber to the collecting vessel, at the same time, forming the finest metal powder.
