Patent number: 11331724
Abstract: An apparatus efficiently preparing ultrafine spherical metal powder includes a housing, a crucible and a powder collection area arranged in the housing. The turnplate arranged in the powder collection area is an inlaid structure. The part inlaid into the body part acts as an atomization plane of the turnplate. The atomization plane is provided with a concentric circular groove, and the turnplate is provided with an air hole. The apparatus is used for preparing ultrafine spherical metal powder by on-by-one droplets centrifugal atomization method, mainly combining the uniform droplet jet method and the centrifugal atomization method, which breaks through the traditional metal splitting model, makes the molten metal in a fibrous splitting, so as to efficiently prepare ultrafine spherical metal powder with narrow particle size distribution interval, high sphericity, good flowability, excellent spreadability, uniform and controllable size, no satellite droplets and suitable for industrial production.
