Abstract (en)
[origin: US4332660A] The invention relates to a storage bunker for a facility which breaks open the solidified crust on an electrolytic cell. The bunker is subdivided into a large container for alumina and a small container for additives. Below the containers are provided a closing-off plate, a dosing facility and a common outlet pipe leading to the break in the crust. When additives are required, these can be fed directly to the small container via the pipe line for supplying alumina. These are then fed to the cell in measured amounts, if desired, mixed with alumina.
