Abstract
A device for producing metallic particles utilizes the Coanda Effect to draw one stream of gas toward another stream of gas flowing over a foil. Molten metal is introduced between the two gas streams, and the resulting interaction breaks up the molten metal flow into particles of appropriate size, shape, composition and the like.
Claims6
A process for producing metallic particles comprising steps of:
- defining a Coanda surface;
- flowing a first fluid along the Coanda surface;
- locating a second fluid adjacent the Coanda surface, said first and second fluids being selected and located with respect to each other so that the flow of said first fluid influences said second fluid to flow in a direction which intersects said first fluid;
- flowing a molten metal adjacent the Coanda surface;
- locating the molten metal flow so that said molten metal flow is located between said first and second fluids so that said molten metal postpones but does not prevent the intersection of said first and second fluids;
- and
- flowing said fluids and said molten metal to an intersection position whereat said first and second fluids intersect, said fluids and said molten metal intermixing thereby breaking up said molten metal flow into metallic particles.
