A magnetic

On the progress of magnetic separation equipment, has a number of special assessment State here only in respect to the magnetic collection and information on

the Comprehensive Review.

1.1 Magnetic Separation progress is characterized by low intensity magnetic separation, using High-performance titanium iron boron permanent magnet cylinder manufacture higher magnetic field strengthSorting machine, drum magnetic separator and pre-selection of large chunks of magnetite Stone, help to improve the development of a weak magnetic separator concentrate grade. Chin-Fe-B permanent magnets (Nd: Fel knife) the maximum energy product can be Up 3.18X10 (T · A / m), drilled alloy is about shirt (SmCo.) Maximum energy product (1.59X10 T · A / m) of z-fold , Bank of ferrite (Sro.6Fe20,) maximum energy product (0.326X105T · A / m)

10 times. Therefore, the use of Chin-Fe-B system easier to increase the magnetic separator magnetic field strength and performance. For example, Germany with a hinge rod iron boron permanent magnet developed 'Permos'Drum magnetic separator magnetic flux density up to 0.4 ~ 0.5T,Can be used wet or dry separation material selection can also be ideal Used to remove the magnetic intensity magnetic separation to the compound a strong material Quality. British Boxmag - Rapid Rail Ltd reamers Boron permanent magnet developed 'Magnadrum' Drum Separator Magnetic field up to 0.3 ~ 0.4T, for the separation of industrial minerals And the abrasive powder.As examples of such large scale equipment, Following the development of Ma On Shan State Mining Institute CTDG1210-shaped Diameter magnetic machine, then type more developed CTDGIS16 Diameter of the magnetic separator, Fe-B magnetic system with money, flat tube surface Are the magnetic field up to 0.4T, for sorting large magnetite Stone. Anshan Design and Research Institute of Ferrous Metal Mines and Shandong Zhang Iron cooperation Jijiawa developed a price 1400mmx1600mm electromagnetic water-cooled magnetic pulley, the average magnetic field for the cylinder surface 0.24T, capacity up to 200t / h, for the pre- 1 350mm of magnetite rock, 8 months, from 667 000 t of the original Excluding iron ore 11.97% of the 75 000 t of tailings, an increase of Cost 534,200 yuan. In order to improve separation equipment Effect, Emei Mineral Resources Research Institute of the conventional magnetic Improve the magnetic slot machine 〔a re-election,〕, the tank top of the coneShaped to cylindrical, permanent magnet ferrite by the lower part of the Round Tower Upper part of the overall magnetic system to form multi-round lineup of scattered magnetic system,Field distribution for the 12 ~ 0kA / m, and with the concentration of self-Control system can control the sub-constituency pulp density 30%-35%, the device application in the Shougang Iron effect Qian'an Results are: with the improvement process, increased grain sorting Degrees, compared to the previous fine grinding fine screening process, the millCapacity of iron concentrate grade and recovery of the same conditions,27.66% capacity increase. This equipment has been developedFor the price 300,600,1500,1800,2500 mm SeriesProducts. In order to improve the grade, Beijing General Research Mining and MetallurgyInstitute
