SEPARATOR Russian patent published in 2005 - IPC

FIELD: equipment for concentration (separation) of fine-dispersed mixtures, in particular, mining industry, for enrichment of iron-ore concentrates.

SUBSTANCE: separator has casing, charging device, discharge device, and magnet with pole tip. Casing is made hermetically sealed. Hopper fixed in casing upper part is equipped with discharge window arranged in lower part of hopper front wall. Chute fixed under hopper is formed as flat hollow member with upper cover made from metal ceramics permeable for working fluid and lower cover made from high-strength material. Chute is positioned so as to be vibrated perpendicular to displacement vector of mixture under separation process. Chute cavity is communicated with working fluid source. Magnet is fixed to casing wall so as to be adjustably moved in vertical plane. Pole tip working side is made arced. Screen arranged between pole tip and mixture under separation process is made in the form of flat hollow member curved along arc of circle with center offset in vertical plane relative to center of circle of pole tip. Flat hollow screen has outer cover made from metal ceramics permeable for working fluid and inner cover made from non-magnetic high-strength material and connected in sealing relationship with outer cover. Screen is movably attached to casing wall for vibration perpendicular to displacement vector of mixture under separation process. Screen cavity is communicated with working fluid source. Discharge devices are made in the form of outlets equipped with sluice gates.

EFFECT: increased capacity and improved quality of extraction in polygradient mode of operation.
