Method of and apparatus for producing metal powder

Abstract

A cooling liquid is injected into and supplied to a cooling tubular body along its inner periphery to form a cooling liquid layer flowing down the inner peripheral surface of the body while revolving. A molten metal is then injected into the cooling liquid layer from the inner peripheral side thereof to divide, rapidly cool and solidify the stream of molten metal with the cooling liquid layer and obtain a metal powder. Since the metal powder is continuously obtained upon flowing down the tubular body along with the cooling liquid, the liquid can be continuously removed from the powder by suitable means, and the power can be subsequently dried continuously.
