A device for separating weakly magnetic first particles, for example hematite particles, from mixture (912) comprising the first particles (913) and less magnetic second particles (914) is presented. The device comprises first magnetizing equipment (901) for producing magnetic field and for moving the mixture so that mutually opposite polarity portions (N, S) of the magnetic field sweep the mixture in a sweeping direction and thereby deflect the direction of movement of the first particles towards the sweeping direction and away from the direction of movement of the second particles. The device comprises also a supply equipment (932) for supplying the mixture to the carrier equipment with the aid of gravitation and a second magnetizing equipment (931) connected to a feed box (920) for producing second magnetic field for deflecting a direction of movement of the first particles differently than a direction of movement of the second particles when the mixture is moved by the gravitation towards the carrier equipment so as to generate, to the mixture arriving at the carrier equipment, a concentration gradient of the first particles. The pre-concentration of the first particles simplifies their separation form the mixture.

The method and systems efficiently extract recyclable materials from a mixed solid waste stream. The methods and systems use sizing, density and dimensional separation to produce intermediate waste streams that are enriched in particular recyclable materials. The recyclable materials can then be efficiently sorted from the individual intermediate streams using mechanized sorting equipment.

L'invention a trait à un séparateur magnétique de particules et/ou morceaux comprenant une première roue magnétique (22) disposée sous une paroi (13) faisant office de surface de glissement pour une première courroie (2) du type courroie transporteuse, ladite paroi (13) décrivant un profil en quart de cercle. Une seconde roue magnétique (33) est disposée en regard de la surface extérieure de la paroi (13). Une seconde courroie fermée (28) entoure la seconde roue magnétique (33) ainsi qu'une roue de guidage (30) de sorte à former une surface de guidage dirigée et se déplaçant vers l'avant. La seconde roue magnétique (33) est entrainée par la première roue magnétique (22) par couplage magnétique sans aucune liaison mécanique. Un frein magnétique (24) est disposé à proximité de la première roue magnétique. Il consiste en un élément mobile (26) comportant plusieurs aimants permanents répartis sur un arc de cercle correspondant à la circonférence de la première roue magnétique et dont les champs magnétiques sont dirigés vers la circonférence de la roue, ces champs magnétiques étant successivement opposés.
摘要:
The invention concerns a magnetic separator (10) of non-ferrous metal conductive elements comprising a first field winding (18) integral with a vertically arranged axis of rotation (20). The rotation of the first field winding (18) in a substantially horizontal plane generates variation of a magnetic field created by the magnets of the first field winding (18). The magnetic separator (10) comprises a dielectric material sorting tray (26) extending parallel to the first field winding (18). The variation of the magnetic field generates the creation of induced currents in the elements passing on the sorting tray (26) and the gliding of the elements on the sorting tray (26) according to trajectories dependent on the interaction of the conductive elements with the induced currents circulating through them. Such a magnetic separator (10) can in particular be used in a selective sorting installation comprising a plurality of magnetic separators (10) arranged in rows and/or columns.

An eddy current separator (10, 10a, 10b, 10c, 10d, 10e, 10f, 10g) and a separation method for separating non-ferromagnetic particles (14) by engaging the particles to force the particles into a primary magnetic field (34) to increase the induced eddy current flow that generates particle magnetic fields such that subsequent release of the particles allows increased magnetic field propulsion to propel the particles distances that vary according to their electrical resistance, densities, shapes and sizes. Different embodiments move the particles into the primary magnetic field by an inclined engagement member (42) that may be a flexible member (42') or a brush (42''), a vertically movable roll (54a), a rotary brush (54b), an upper auxiliary conveyor (64), an upper belt reach (26) of a belt conveyor (16), a vibratory member (26') of a vibratory conveyor (16'), and an inclined gravity slide (70) that may be a curved trough (72).
