摘要： System and method for producing metal or alloy powder are described which comprises a housing defining a cylindrical chamber having an inlet and an outlet and a plurality of passageways in the form of fluid nozzles defined through the housing wall along axes oriented at preselected angle to the chamber wall, the passageways being operatively connected to a pressurized source of fluid so that fluid is injected into the chamber as fluid jets of preselected flow rate and is swirled in controllable helical fashion generally toward the chamber outlet, and a molten source of metal or alloy operatively connected through a molten metal nozzle and atomization die to the inlet of the chamber for directing molten particles into contact with the fluid jets for solidification and cooling along downward helical paths within the chamber. A plurality of concentric annular bins may be disposed near the outlet of the chamber for collecting powder formed within the chamber.
