Abstract

L'invention concerne un dispositif conçu pour fournir, par intermittence, un matériau en poudre (65) à une multitude de tuyaux d'alimentation (52) afin de fournir des charges de matériau en poudre (65) à différentes zones d'un électrolyte fondu (5) dans une cellule d'extraction électrolytique de métal. Le dispositif décrit dans cette invention comprend un dispositif (54, 55, 56a, 57, 58) permettant de mesurer des quantités de matériau en poudre et de déverser, par intermittence, les quantités mesurées sur au moins une surface de séparation (51) inclinée et/ou verticale présentant une forme conique ou pyramidale. Chaque quantité de matériau en poudre (65) mesurée est séparée en une multitude de charges au fur et à mesure que ledit matériau en poudre se déverse sur la ou les surfaces de séparation (51); ces charges correspondent aux multiples tuyaux d'alimentation (52) et sont acheminées vers eux.
