Dry magnetic separator

dry drum magnetic separator is commonly used equipment equipment of iron ore and manganese ore, the prevailing strong magnetic separation mineral processing equipment.Divided into: a three-strong intensity roll dry electromagnetic separator, two cylinder two roll dry magnetic separator, a drum roll dry coolant magnetic separators;Dry magnetic separator is widely used in separating less than 2-3 of the weakly magnetic minerals and rare metals ore selection.It has a tangentbifurcation (φ = 900 mm in diameter) and double-disc (φ = 576 mm) and three (φ = 600 mm) three.Up to 8,801,440,000 a/m magnetic field strength.With φ 576 mm dual disc applications.Body of the magnetic separator is a "mountain"-shaped electromagnet with Swivel suspension induction disc composed.Disc as a dish turned upside down, pointed teeth, its diameter is larger than the ore belt width is about one-second, disc using worm gear deceleration transmission, via handwheel adjustable disc with the polar distance between the electromagnet (range 0-20) mm.In order to prevent blockage in the feed cylinder is equipped with a weak magnetic field magnetic poles, can advance in the fed to drain of strongly magnetic minerals.

Working principle of magnetic separator

After the pulp is feed tank flows into the tank, spray in feeding under the action of water currents and particles diffuse into the tank to the mining area.Effect of the magnetic field, magnetic particles of Dry drum magnetic separator agglomeration forming "magnetic" or "flux", "magnetic" or "flux" magnetic force in the pulp, and moving toward the poles and are adsorbed on the cylinder.Due to pole of polar along cylinder rotating direction is alternating arranged of, and in work Shi fixed not moving, "magnetic mission" or "magnetic chain" in with cylinder rotating Shi, due to pole alternating and produced magnetic mixing phenomenon, was inclusions in "magnetic mission" or "magnetic chain" in the of gangue, non-magnetic mineral in flip in the shedding down, eventually was sucking in cylinder surface of "magnetic mission" or "cross belt magnetic separator chain" that is fine
mine.Concentrate with the cylinder turned to edge magnetic magnetic system the most weakness, dumping was unloading hoses flush current action to concentrate tank, if is the magnetic roller, brush roll for dumping was carried out.Non-magnetic or weakly magnetic minerals are left outside in the pulp slurry discharge trough, which is tailing.
