<p>PROBLEM TO BE SOLVED: To eliminate adverse effects such as greasing generated by the shape and the diameter of particles, the electrification amount and the like by disposing a plurality of classifying and separating edges on the positions where powder is scattered while being dropped at the intervals in the vertical direction. SOLUTION: Powder 2 introduced from a raw material introduction opening is jetted out of a nozzle 1 by an air injection means, and while the powder 2 is rotated facing downward in the forward moving direction, the powder is accelerated on an ejector section and jetted into a shape separating machine 3. A plurality of classifying and separating edges 6 are disposed at the intervals in the vertical direction on the positions where the powder 2 is scattered while being dropped, and the speed of the particles 4 of irregular shape is lost as their particle drag coefficient of spherodized particles is small, and the particles overcome the fluid resistance of jet flow and scatter farther.</p> |
