ABSTRACT:
A method for producing spherical metal particle uses a molten metal reservoir for containing a molten metal, a rotary drum having a number of teeth onto which the molten metal is to be adhered one after another and a driving means for rotating the rotary drum so that the molten metal adhered to each of the teeth can be scattered from the teeth before even a part of each molten metal adhered to the teeth solidifies. At least one tooth of the rotary drum is dipped into the molten metal contained in the molten metal reservoir. The molten metal adhered to the teeth is scattered from the teeth before any portion of it has solidified by means of centrifugal force acting on the rotary drum. The molten metal assumes a spherical or similar shape during its trajectory due to surface tension. It cools by atmospheric cooling to solidify as discrete metal particles of substantially uniform diameter. The diameter of the solidified metal spheres can be predetermined by the uniform amount of the molten metal adherent on each tooth due to the uniform surface area of each of the teeth.
