Abstract

Procédé de recyclage d’au moins un aimant (D) de forte puissance dans une installation (1) de recyclage, le procédé comprenant une étape de démagnétisation de l’au moins un aimant (D), le procédé étant caractérisé en ce que, avant l’étape de démagnétisation, il comprend une étape de placement de l’aimant à l’intérieur d’un récipient (8) de neutralisation, ledit récipient (8) de neutralisation comprenant des parois (9, 10) formant un réceptacle fermé pour contenir ledit au moins un aimant (D), les parois (9, 10) étant réalisées au moins en partie en matériau amagnétique, l’aimant (D) étant contenu dans le récipient (8) de neutralisation pendant au moins une partie de l’étape de démagnétisation. Figure pour l’abrégé : figure 1Process for recycling at least one high-power magnet (D) in a recycling installation (1), the process comprising a step of demagnetizing the at least one magnet (D), the process being characterized in that, before the demagnetization step, it comprises a step of placing the magnet inside a neutralization container (8), said neutralization container (8) comprising walls (9, 10) forming a closed receptacle to contain said at least one magnet (D), the walls (9, 10) being made at least partly of non-magnetic material, the magnet (D) being contained in the neutralization container (8) for at least part of the demagnetization stage.
