Abstract (en)
[origin: FR2894988A1] Extraction of an anode stub (110) and molds attached to a spent anode comprises: (a) placing the stub between a stop device (200) and a breaker (300); (b) placing the stub against a first stop (211); (c) displacing the breaker towards the stub to fragment it; (d) evacuating the fragments of the stub; (e) further displacing the breaker to block the attached molds against a second stop and detach them with a billet (122); (f) stopping and withdrawing the breaker. In two successive well separated steps, the stub fragments and the hooked molds are detached and directed to a recycling plant. An independent claim is also included for a machine for extracting anode stubs and molds attached to an anode.
