CA 2563256

A protrusion (21b) is formed in the central region on the inner surface (21c) of a first disc plate (21) constituting the end part on the oblique downward side of a rotary drum (2). Powder (11) in the vicinity of the other end (first disc plate (21)) lifted forward in the rotational direction as the rotary drum (2) rotates comes in contact with the surface of the protrusion (21b) when the powder flows gravitationally backward in the rotational direction. The powder then flows obliquely upward while being guided by the surface of the protrusion (21b). Consequently, stagnation phenomenon of the powder (11) is less likely to occur in the vicinity of the other end (first disc plate (21)).

Il est prévu une partie saillante (21b) formée dans la région centrale sur la surface interne (21c) d~une première plaque à disque (21) constituant la partie extrême sur le côté descendant oblique d~un tambour rotatif (2). La poudre (11) au voisinage de l'autre extrémité (première plaque à disque (21)) soulevée vers l~avant dans le sens de rotation tandis que le tambour rotatif (2) tourne, vient au contact de la surface de la partie saillante (21b) lorsque la poudre s~écoule par gravitation vers l~arrière dans le sens de rotation. La poudre s~écoule ensuite dans le sens oblique vers le haut tout en étant guidée par la surface de la partie saillante (21b). Il s~ensuit que le phénomène de stagnation de la poudre (11) a moins de chances de se produire au voisinage de l'autre extrémité (première plaque à disque (21)).
