Abstract
A method for gas flow separation of powders includes establishing a stream of mixed powders; and applying a cross-flow stream of gas to the stream of mixed powders such that powders of different density are displaced by the cross-flow stream to a different extent, thereby forming separate streams of powders having different density. An apparatus is also disclosed.
Claims17
A method for gas flow separation of powders, comprising:
- establishing a vertical stream of mixed powders;
- and
- applying a cross-flow stream of gas to the vertical stream of mixed powders such that powders of different density are displaced by the cross-flow stream to a different extent, thereby forming separate streams of powders having different density, wherein the establishing step comprises flowing the mixed powders through a nozzle to create the vertical stream of mixed powders, and wherein the nozzle has a straight-line configuration and establishes a nozzle per inch of between 100 and 2,400 nozzles per inch (NPI).
An apparatus for gas flow separation of powders, comprising:
- a nozzle for establishing a stream of mixed powders, wherein the nozzle has a straight-line configuration;
- and
- a source of a stream of gas oriented to direct a cross-flow stream of gas across the stream of mixed powders such that powders of different density are displaced by the cross-flow stream to a different extent, thereby forming separate streams of powders having different density, wherein the nozzle establishes a nozzle per inch of between 100 and 2, 400 nozzles per inch (NPI).
