Title (EN) POWDER PURGING APPARATUS AND METHOD
(FR) APPAREIL ET PROCÉDÉ DE PURGE DE POUDRE
Abstract:
(EN) The invention relates to an apparatus and method for purging charged powder particles from a mixture of said powder particles and ferromagnetic carrier particles. Purging is effected by moving the carrier particles relative to a first side of a support surface which supports said carrier particles, while attracting the powder particles towards an attracting surface which is spaced apart from said support surface and at a different potential than said support surface. The movement of the carrier particles is driven by moving the support surface relative to a plurality of magnets which are arranged on a second side of the support surface opposite to said first side, for attracting the carrier particles to said first side.
(FR) La présente invention concerne un appareil et un procédé pour purger des particules de poudre chargées d'un mélange desdites particules de poudre et de particules porteuses ferromagnétiques. La purge est effectuée par déplacement des particules porteuses par rapport à premier côté d'une surface de support qui supporte lesdites particules porteuses, tout en attirant les particules de poudre vers une surface d'attraction qui est espacée de ladite surface de support et à un potentiel différent de ladite surface de support. Le déplacement des particules porteuses est commandé par déplacement de la surface de support par rapport à une pluralité d'aimants qui sont agencés sur un second côté de la surface de support opposé audit premier côté, pour attirer les particules porteuses vers ledit premier côté.
