    Abstract: An apparatus for manufacturing metal powder according to the present invention is a metal powder manufacturing apparatus, in which molten metal is broken up, and liquid droplets of the atomized molten metal are cooled by spraying cooling water using a cooling water spraying nozzle provided inside a chamber. The cooling water spraying nozzle is provided such that cooling water is sprayed in a fan shape, and cooling water spraying nozzles provided at different heights have increasing angles of inclination with respect to the inner wall of the chamber as the heights thereof are reduced, thereby decreasing a deviation between flying distances of the molten metal liquid droplets to efficiently manufacture metal powder having uniform properties.
