ABSTRACT:
An apparatus and method for splitting a mass of fluidizable powder into a plurality of powder streams and conveying the powder streams through a plurality of ducts. The apparatus comprises a powder splitter defining a chamber, a plurality of hollow ducts each having an entrance communicating with the chamber, and a gas source including a plurality of gas nozzles within the ducts and directed outwardly of the chamber. The gas nozzles propel gas jets into the ducts so that portions of the fluidizable powder are conveyed through the ducts. A particularly preferred apparatus is utilized for conveying a plurality of alumina powder streams to an aluminum electrolysis cell.
