Apparatus for successively fusing small particles of nonferrous metal

An apparatus for fusing small particles of nonferrous metal comprising:

• a molten metal chamber for containing a molten metal formed from a metal raw material which was subjected to heating and fusing treatment;
• a fusing chamber for fusing small particles of nonferrous metals by introduction of the particles into a high temperature molten metal;
• a molten metal tank contained within said fusing chamber and provided adjacent to said molten metal chamber;
• a pump provided in the fusing chamber for circulating molten metal between the molten metal chamber and the fusing chamber;
• a delivery pipe connecting an outlet port of the pump with the molten metal chamber by penetrating the molten metal tank;
• and
• a cylindrical swirl generation chamber provided in the fusing chamber at a suction side of the pump, said swirl generation chamber having a circular inner peripheral wall, an introduction passage extending tangentially to a side surface thereof and a discharge port of circular cross section provided substantially at the middle of a bottom surface thereof.
