Abstract
(EN)
A powder separator and powder separation method by which powders to be separated can be separated with satisfactory precision. This separator comprises: a vessel (30) to which powders to be separated (4) comprising a heavy powder (4a) and a lightweight powder (4b) and medium particles (64) having a larger particle diameter than the powders (4) are fed; a vessel-vibrating part (50) for vibrating the vessel (30); and a gas-blowing part (40) which blows a gas into a medium-particle layer (65) in the vessel (30) to discharge the lightweight powder (4b) outside the medium-particle layer (65) together with the gas.

La présente invention concerne un séparateur de poudre et un procédé de séparation de poudre grâce auquel des poudres devant être séparées peuvent être séparées avec une précision satisfaisante. Ce séparateur comprend : un récipient (30) dans lequel on ajoute des poudres devant être séparées (4) comprenant une poudre lourde (4a) et une poudre légère (4b) et des particules moyennes (64) ayant un plus grand diamètre de particules que les poudres (4) ; une partie de vibration du récipient (50) destinée à faire vibrer le récipient (30) ; et une partie soufflant du gaz (40) qui souffle un gaz dans une couche de particules moyennes (65) dans le récipient (30) de façon à extraire la poudre légère (4b) de la couche de particules légères (65) conjointement avec le gaz.
