  • Method and apparatus for powder distribution
    Patent number: 5667099
    Abstract: Previously weighed powder is radially scattered by centrifugal force. The scattered powder is introduced into a plurality of powder chambers via a plurality of powder inlets arranged along the circumferential direction. The powder, dispersed almost uniformly with respect to the circumferential direction, is distributed at a given ratio corresponding to the ratio of the areas of the powder inlets. The powder is accurately and efficiently distributed into plural portions of a given weight each without melting, aggregating or crushing.
