Abstract
A method and means for application of anode covering material (ACM) in an electrolysis cell for aluminium production where the cell being of Hall-Héroult type with prebaked anodes. The cell contains a cathode pot with a rectangular footprint and a superstructure with a gas collecting hood that lays onto the top of the cathode pot. A floor construction at least substantially surrounds the cell at a level below the top of the cathode pot and ventilation openings provided with grates are arranged in the floor in the close vicinity to the cell. The superstructure's hood is provided with removable lids that are removed for giving access to the cell's anodes through openings. ACM is applied via a feed tube to cover the anodes and the deposit of ACM is supported by a shuttering.
