Abstract (en)

[origin: CA3051784A1] The present invention relates to a device (10) for supplying alumina to an electrolytic cell (100), comprising a boring part (22), a tubular sleeve (23) surrounding the boring part, the sleeve comprising a lower opening and a first gas discharge opening (25), a pipe (26) for feeding alumina into the tubular sleeve (23) comprising a second alumina feeding opening and an orifice in communication with the tubular sleeve, wherein the tubular sleeve (23) and the pipe (26) are arranged so that more than 90% of the gases entering the tubular sleeve (23) via the lower opening (24) leave the tubular sleeve (23) via the first gas discharge opening (25).
