Filed:

Aug 31, 1982

Appl. No.:

6/413513

Inventors:

Robert A. Ramser - New Kensington PA
Daniel R. Barch - Natrona Heights PA
Kalman E. Buchovecky - Oakmont PA
Ray A. Kuchera - Rockdale TX

Assignee:

Aluminum Company of America - Pittsburgh PA

International Classification:

B01J 204

US Classification:

425 7

Abstract:

An improved apparatus for the production of particulate metal is disclosed. The apparatus includes a containment vessel having a sidewall and a bottom plate, a source of metal external to the vessel, nozzle means carried by the bottom plate and providing communication between the vessel and the external source of metal, and release means associated with the sidewall to inhibit deposition of the particulate metal on the sidewall.

International Classification:

B29B 900

US Classification:

264 12

Abstract:

An improved system for the production of particulate metal is disclosed. The system comprises a containment vessel having a sidewall extending to an endwall, a source of metal external to said vessel and nozzle means carried by said endwall, said nozzle means including a central bore and providing communication between said vessel and said external source of metal, the sidewall and endwall cooperating with the nozzle means to seal off the interior of said vessel and the metal particles therein from the area adjacent said source of molten metal. Further, the system comprises a source of atomizing gas flowing through said nozzle means into said vessel and means for redirecting said atomizing gas flowing into said vessel into said central bore to remove deposition in said bore.
