Abstract
In accordance with the invention, apparatus for the production of atomized metal is provided comprising a containment vessel having a sidewall terminating in an end wall through which atomizing gas and molten metal from a molten metal source enter the vessel through nozzle means sealed thereto. A restricted air ingress port is provided in the vessel spaced from the end plate, the sidewall and the end plate cooperating with the nozzle means to seal off the interior of the vessel and the metal particles therein from the area adjacent the source of molten metal. The source of molten metal includes a reservoir having at least a portion above the nozzle means whereby the metal level in the reservoir provides an adjustable pressure head for the metal entering the vessel through the nozzle means which is adjusted by varying the level of the molten metal in the reservoir.
