what is magnetic separation？

There are many kinds of magnetic separators: they can be divided into dry strong magnetic disk type magnetic separator, flat ring type strong magnetic field magnetic separator, SHP type wet strong magnetic field magnetic separator, and vertical ring wet strong magnetic field magnetic separator. Dry magnetic separator: Dry magnetic separator is a commonly used iron ore equipment and manganese ore equipment, and the mainstream strong magnetic separator mineral processing equipment. Divided into: one-tube three-roll dry strong magnetic separator, two-barrel two-roll dry magnetic separator, one-tube one-roll dry magnetic separator; dry strong magnetic disk disc magnetic separator is widely used for sorting less than 2 - Re-selection of 3 mm weak magnetic minerals and rare metal ores. It has three types of single disc (diameter φ = 900 mm), double disc (φ = 576 mm) and three discs (φ = 600 mm). The magnetic field strength can reach 880-1440 kA/m. Among them, there are many double disc applications with φ576 mm. The main part of the magnetic separator is composed of a "mountain" shaped electromagnet and a rotatable suspension induction disc. The disc is like a flip-flop dish with a diameter that is about one-half larger than the width of the ore belt. The disc is driven by a worm-worm gear, and the pole between the disc and the electromagnet can be adjusted by the handwheel. Distance (adjustment range 0-20) mm. In order to prevent clogging, a weak magnetic field magnetic pole is placed in the ore cylinder to pre-discharge the ferromagnetic mineral in the feedstock.

1. Flat-ring magnetic separator: The structural characteristics of the flat-ring strong magnetic field magnetic separator are closed loop magnetic circuit with large loops, copper coil wound coil, low voltage and large current excitation, water cooling and cooling, teeth The board is used as a sorting medium. The machine is composed of ore feeding device, concentrate and medium mine flushing device, sorting rotary ring, magnetic system, ore collecting device, transmission device and DC power supply. The magnetic structure is novel. It consists of inner and outer concentric annular magnetic moments, radial cores and coils. The main shaft is located at the center of the annular closed magnetic circuit, and no magnetic lines pass. The coil is wound from a square copper tube of 22 x 15 x 2 mm, each outer core coil 33 turns, the inner core coil 66 turns, and abuts against the pole. The heat dissipation of the coil adopts the water internal cooling method, which has the advantages of good cooling effect, low cost and no noise.

2, SHP type magnetic separator: SHP type wet magnetic field magnetic separator is also called double disc strong magnetic separator, which is a magnetic separation equipment which is made by the relevant data of foreign strong magnetic machine. Two upper U-shaped yokes are mounted on the steel frame, and an exciting coil is placed on the horizontal portion of the yoke, and forced cooling is performed by an axial flow fan. The upper and lower sorting discs are mounted on a vertical central axis, and the disc rotates between two opposing magnetic poles, and a large closed magnetic circuit is formed by the U-shaped yoke magnetic poles and the upper and lower two sorting discs, and The upper and lower sorting disks are the main circuits in the magnetic circuit. There are 17 sorting chambers on the periphery of the disc, and a multi-layer magnetic cleat is installed in the chamber to become an inductive magnetic pole. The collecting pipe is arranged on the disc, and there is a collecting tank below, and the corresponding part of the collecting pipe is provided with a feeding nozzle.

3, vertical ring wet magnetic separator: φ800 mm vertical ring wet magnetic separator mainly consists of a metal ring. The ring rotates vertically between the two magnetic poles, and the lower part passes through the magnetic field. The slurry is fed into the ring through the inner ring of the ring through the inner ring of the ring. The weak magnetic ore adheres to the surface of the medium ring and rises to the magnetic field with the rotation of the ring. The very weak top is flushed into the concentrate tank by high pressure water. The non-magnetic ore particles flow into the tailings trough due to the magnetic force passing through the gap of the medium ball. The main advantage of the vertical ring wet magnetic field magnetic separator is that it overcomes the disadvantage of the horizontal ring (flat ring) magnetic separator being easy to block. This is because the medium rolls in the ring with the ring rotation, which destroys the orientation formed by the medium magnetization. The arrangement acts as a degaussing effect, thereby improving the clogging phenomenon. The magnetic separator test shows that the specific magnetic susceptibility for hematite, siderite, ilmenite, chromite, wolframite, antimony ore, manganese ore, garnet, smectite and hornblende is greater than 15×. A sorting index of fine particle weak magnetic minerals of 10-6 cm 3 /g can obtain better sorting index.

4. Drum type sorting machine: The drum type sorting machine is to install a hanging type magnetic drum on one end of the material conveying machine, when the waste enters the magnetic field of the drum. The magnetic substance is sucked by the drum. And when the drum rotates in the non-magnetic area, the non-magnetic substance is separated from the magnetic substance because it is not sucked by the drum.

5, magnetic roller magnetic separator: magnetic roller, also known as magnetic pulley, there are two kinds of permanent magnets and electromagnetic, the application of more permanent magnet roller, the solid waste is evenly distributed on the belt conveyor, when the waste passes the magnetic roller, A non-magnetic or weakly magnetic substance is separated from the belt surface by centrifugal force and gravity; and a magnetically strong substance is attracted to the belt by magnetic force and is carried by the belt to the lower part of the magnetic roller. When the belt is separated from the magnetic roller, the belt is straightened. At the time, the magnetic field strength is weakened and falls into the magnetic substance collecting tank. This equipment is mainly used for the crushing of industrial solid waste or municipal solid waste or in front of the incinerator.

6. Wet permanent magnet cylindrical magnetic separator: The wet permanent magnet cylindrical magnetic separator is of the reverse flow type. Its feeding direction is opposite to the circular rotation direction or the moving direction of the magnetic substance. The material is directly fed into the cylinder under the magnetic system from the feed box. The non-magnetic material is discharged from the discharge port on the bottom plate on the left side of the magnetic system. The advancing substance moves to the magnetic material discharge end with the cylinder against the feeding direction, and is discharged into the magnetic substance collecting tank. The equipment is suitable for the recovery of particle size "0.6 mm strong magnetic pre-granules. For example, in the recovery of iron from iron dust and iron oxide scales and the weighting of recycled heavy medium sorting products.
