Title (EN) CROSSING CONVEYOR-BELTS MAGNETIC SEPARATOR
(FR) SEPARATEUR MAGNETIQUE A BANDES TRANSPORTEUSES CROISEES
Abstract: front page image
(EN)The magnetic separator with crossing conveyor-belts separates materials having different magnetic susceptibilities. In this separator, the lower belt (1) conveys the material to be treated where the upper belt delivers the material separated. On each side of the belt (2, 3, 4), is a frame which forms a permanent magnetic circuit. Each of these frames is formed by four magnets with oriented magnetization (9, 10, 11, 12, 13, 14, 15, 16) connected in pairs by soft iron strips (5, 6, 7, 8) and interplated elements (17, 18, 19, 20) also made of soft iron. These elements are interconnected by pole pieces (21, 22) forming a working clearance. This arrangement aims at providing a higher efficiency to the separator by reducing the losses due to the leak flux.
(FR)Le separateur magnetique a bandes transporteuses croisees separe des matieres ayant des susceptibilites magnetiques differentes. Dans ce separateur la bande (1) du dessous transporte la matiere a traiter tandis que la bande du dessus livre la matiere separee. De chaque cote de la bande (2, 3, 4) se trouve un cadre constituant un circuit magnetique a aimant permanent. Chacun de ces cadres est forme de quatre blocs-aimants a magnetisation orientee (9, 10, 11, 12, 13, 14, 15, 16) connectes deux a deux par des parties en fer doux (5, 6, 7, 8) et des pieces intercalaires (17, 18, 19, 20) egalement en fer doux. Ces dernieres sont reliees entre elles par des pieces polaires (21, 22) formant un entrefer de travail. Cette disposition vise a une meilleure efficacite du separateur en diminuant les pertes par flux de fuite.
