Electromagnetic Gravity Separator panning machine in the application of iron ore in the process of panning machine belonging to the electromagnetic gravitational magnet for highly efficient processing of magnetic separation crushing equipment. Magnetic minerals at home and abroad with common magnetic separation equipment for the Drum Separator and desliming ducts. As a result of these higher magnetic field strength equipment, magnetic field of large, magnetite (including artificial magnetite) sorting reunion of a strong magnetic effect. So there "magnetic inclusion" and "non-magnetic inclusions concentrate containing more gangue, seriously affecting concentrate grade. In addition existing equipment caused long and complicated process; middling cycle overload; high consumption, high processing costs.

Electromagnetic Gravity Separator panning machine is rough Concentrate efficient Featured equipment, materials selected regardless of the final concentrate is low-grade intermediate rough or magnetic separation concentrate, the magnetic separator can be selected export-producing over 65 percent of the high - grade magnetite concentrate. Ore grade 50-57% increases in concentrate grade-10-15%; ribbons ore grade 60-63% Concentrate Commodities column increases for 3-6%. Electromagnetic panning machine can be used gravity filtration equipment before the effective concentration, the concentration of up to 60 ‰ more, raising both grade role. Electromagnetic gravity of panning and domestic similar equipment-magnetic-electromagnetic machine and Russia concentrator, compared to the low power consumption, high processing power per unit area, without equipment parts, no noise pollution, do not have the characteristics of lubrication maintenance, equipment use safe and reliable.

Electromagnetic gravity machine is a new type of panning weak magnetic separation equipment. The equipment from the original permanent magnet magnetic-sorting machine and the principle of movement of magnetic field on the combined effects of magnetic minerals. The design of a top-down gradually reduce the intensity of the magnetic field of new election equipment. Concentrate is to improve the quality of the ideal equipment. Use of the magnetic and electromagnetic replace the permanent magnet magnetic system, the constant magnetic field into the magnetic field can always adjust meet to mine ore volume and change the optional sorting effect.
Electromagnetic Magnetic intermittent use of DC power, so that the coil magnetic sorting time, when no. Upgrading the original magnetic-Machine reunion - dispersion - the role of reunion.
Electromagnetic gravity of top-down design panning eight electromagnetic coil, the middle circle of top six to take power, resulting in the downward movement of the magnetic minerals magnetic field; increase of the magnetic minerals sorting results .
According need sorting process is designed to point the upper ore sorting the magnetic field strength, the bottom of the magnetic special low. Balance the sorting process at the top of mine to increase water velocity high, and the lower speed up the problem of low water.
The equipment installed pulp proportion of detection devices, access at any time of the electromagnetic machine-ore changes when ore increased, the proportion of pulp increased, the system automatically increases the electromagnetic field of magnetic intensity, increase the magnetic minerals downward suction; When the mine reduced, the reduction in the proportion of pulp automatically reduce electromagnetic system of the magnetic field strength, and to reduce the magnetic minerals downward suction.
Equipment control system has fundamentally changed with contacts, the regulator ladder adjustment of the magnetic field the traditional way, using SCM control of the means of power regulator has greatly improved the system's reliability.
The equipment configuration of the automatic control system, automatic detection sorting through the changes in the proportion of pulp, and other automatic adjustment of the election magnetic field strength; do not need artificial participation equipment always work in the best condition.
      Electromagnetic gravity of the current panning in the Shougang Mining Company Waterworks boulder and iron ore concentrator and a comprehensive promotion. Practice made by the original magnetic-than-better results.
Waterworks Concentrator in December 2003 to promote, with the original magnetic reunion of production comparison study, the results
: Electromagnetic panning machine gravity concentrate grade than the original magnetic reunion 2.2% -0.074 mm particle size for the overflow 63.99%, concentrate -0.074 mm to 81.85 percent; overflow fine than 17.86%; than to the fine ore 6.16 % concentrate grade increased 4.67 percent. reunion of the original and completely the opposite.
Inspection data are as follows: electromagnetic gravity of the original magnetic panning reunion

Dashi iron ore in the February 2004 after transforming the electromagnetic gravitational sorting machine panning effects were studied. The result: Concentrate -0.074 mm content of 76.1%, and to mine 75.5 percent, an increase of 0.6 percent. Concentrate Grade raise 4.15 percent. Specific study are as follows:

There are five purposes:
       ① Featured magnetic separation plant low-grade magnetite concentrate;
       ② Featured magnetic separation process crude Concentrate (ORE) direct access to the ultimate qualified concentrate;
       ③ easy election from magnetite concentrate production super magnetite concentrate;
       ④ efficient as a filter before enrichment equipment, underflow concentration up to 60% ~ 65%;
       ⑤ Featured pyrrhotite containing the magnetic separation concentrate to reduce the sulfur content in concentrate.
     Featured by the gravity of low-grade concentrate panning to the ore grade of 60 ~ 63% increases in grade 4 ~ 8%, ore grade to 55 ~ 60%, increases in grade 8 to 10%, to 50 ~ 55 ore grade % grade increases 10 to more than 15 percent Featured magnetic separation process ore can be directly obtain the ultimate high grade concentrate ore grade to 50 ~ 60% concentrate grade up more than 65%, at the same time simplify the process, the Range energy conservation, energy gain if maintaining concentrate grade unchanged, using gravity for panning up production and consumption, reduce costs purpose of gravity-panning machine Featured election magnetite concentrate to produce super magnetite Concentrate grade up to 70 ~ 72%.
