Abstract

L'invention concerne un séparateur magnétique linéaire à courants de Foucault dans lequel le matériau à traiter est transporté au moyen d'une goulotte vibratoire ou bande transporteuse sur le rotor magnétique dans la direction de son axe, obligeant le matériau à parcourir longitudinalement tout le rotor magnétique. Les particules conductrices électriques sont déviées latéralement par la répulsion des courants de Foucault générés dans leur masse par l'action du champ magnétique alternatif produit par le rotor lors de sa rotation.
