ABSTRACT:
An outer tube 5 is integrally rotated with a rotating disk 17. A powder supply passage 16 for supply of powder particles is formed between an inner tube 15 and the outer tube 5. A lower end of the inner tube 15 is secured to a sub-disk 23, and a distributing passage 25 is formed as a space between the sub-disk 23 and the rotating disk 17. Air including powder particles introduced into a separation passage 41 is separated into air and powder in the separation passage 41, and the particles are fed to the distributing passage 25 through the powder supply passage 16. The powder particles falling in the powder supply passage 16 undergo a swirling motion in accordance with the rotation of the outer tube 5, and owing to the swirling motion, the powder particles in the powder supply passage 16 are distributed uniformly in the circumferential direction.
