METHOD AND APPARATUS FOR PRODUCING FINE SPHERICAL POWDERS FROM COARSE AND ANGULAR POWDER FEED MATERIAL
A high temperature process is provided, which can melt, atomize and spheroidize a coarse angular powder into a fine and spherical one. it uses thermal plasma to melt the particle in a heating chamber and a supersonic nozzle to accelerate the stream and break up the particles into finer ones.
