FINE-POWDER PRODUCTION DEVICE AND METHOD

摘要

The present invention relates to a fine-powder production device and method wherein, in the first instance, a molten raw material is disintegrated by using gas jetting, and, in the second instance, a fine powder of which the characteristics are controlled is produced by using liquid jetting. The fine-powder production device according to the present invention comprises: a molten metal supply unit which supplies a molten metal by melting a raw material; a gas jetting unit which is positioned underneath the molten metal supply unit and disintegrates the molten metal so as to form droplets by jetting a gas comprising an inert gas; a liquid jetting unit which is positioned underneath the gas jetting unit, and forms a fine powder by jetting a liquid, with adjustment of the position of jetting onto the drops formed by means of the gas jetting unit; and a fine powder capture unit into which falls a fine powder formed by means of the liquid jetting unit.
