Abstract:
(EN) Provided is a magnetic separator that can efficiently separate ferromagnetic particles from powder and granular material even when the powder and granular material that includes the ferromagnetic particles is processed in a large volume and when the layer of powder and granular material supplied is thick, can perform magnetic sorting at a low cost without requiring complex processes, wastewater treatment, or the like, and further can resolve problems of ferromagnetic particle adherence peculiar to conveyor belt type magnetic separators. The magnetic separator has at least a pair of guide rolls and a conveyor belt that is stretched across the pair of rolls and transports the powder and granular material that includes the ferromagnetic particles. Either one of the guide rolls is a hollow roll, and in the hollow part thereof, has a magnetic roll whereon are disposed a plurality of magnets along the inner peripheral surface of the guide roll sequentially in the circumferential direction with a space therebetween such that different magnetic poles alternate. The magnetic separator is provided with a shielding wall for shielding magnetic lines of force from the magnets by covering a circular arc region on the outer peripheral surface of the one guide roll except for a circular arc region whereon the conveyor belt is wrapped.
(FR) L'invention concerne un séparateur magnétique qui peut séparer efficacement des particules ferromagnétiques d'un matériau pulvérulent et granulaire même lorsqu'un volume important de matériau pulvérulent et granulaire qui comprend les particules ferromagnétiques est traité et lorsque la couche de matériau pulvérulent et granulaire transmise est épaisse, peut réaliser un tri magnétique à faible coût sans nécessiter de processus complexes, de traitement des eaux usées, ou similaire(s), et peut en outre résoudre des problèmes d'adhérence de particules ferromagnétiques propres aux séparateurs magnétiques du type à bande transporteuse. Le séparateur magnétique comprend au moins une paire de rouleaux de guidage et une bande transporteuse qui est tendue en travers de la paire de rouleaux et transporte le matériau pulvérulent et granulaire qui comprend les particules ferromagnétiques. L'un des rouleaux de guidage est un rouleau creux, et dans sa partie creuse, présente un rouleau magnétique sur lequel est disposée une pluralité d'aimants le long de la surface périphérique interne du rouleau de guidage séquentiellement dans la direction circonférentielle avec un espace entre eux de sorte que différents pôles magnétiques se succèdent. Le séparateur magnétique est doté d'une paroi de protection permettant de protéger des lignes de force magnétiques des aimants en recouvrant une région en arc de cercle sur la surface périphérique externe du rouleau de guidage, à l'exception d'une région en arc de cercle sur laquelle la bande transporteuse est enroulée.
(JA) 強磁性粒子を含む粉粒体を大量に処理する場合や供給される粉粒体の層が厚い場合でも、粉粒体から強磁性粒子を効率よく分離し、かつ複雑な工程や廃液処理などを必要とせずに低コストで磁力選別することができ、さらには、ベルトコンベア式の磁力選別装置に特有の、強磁性粒子の付着の問題を解消し得る、磁力選別装置を提供する。 少なくとも1対のガイドロールと、前記ロール対間に張り渡され強磁性粒子を含む粉粒体を搬送するコンベアベルトと、を有し、前記ガイドロールのいずれか一方は中空ロールであって、該中空部に、前記ガイドロールの内周面に沿って複数の磁石を周方向に間隔を置いて異磁極が交互に並ぶ列状に配置した、磁石ロールを有し、前記ガイドロールのいずれか一方の外周面における、前記コンベアベルトが巻き回される円弧領域を除く円弧領域を覆って前記磁石からの磁力線を遮断する、遮蔽壁を備える。
