Application of new magnetic separator (1) Magnetic agglomeration re-selection machine The equipment was successfully trial-produced in early 1985, and industrial testing was started at Shougang Water Plant and a good sorting effect was obtained. An appropriate magnetic field intensity distribution is formed throughout the sorting zone of the device, a relatively uniform weak magnetic field, and a small magnetic field gradient. The separation of magnetic particles and gangue particles depends mainly on the magnitude of gravity and rising water flow. The industrial production practice of the magnetic agglomeration re-election process shows that the equipment can increase the concentrate grade by 2 to 3 percentage points. In addition Shougang Mining Company developed the adjustable magnetic reunion re-election machine and gather electromagnetic machine, in Shougang, Dashi iron ore beneficiation plant has been applied. (2) Magnetic separation column The magnetic separation column is a new type of high-efficiency magnetic separation equipment . The weak magnetic cluster formed by the magnetic part of the material under the weak magnetic field moves downward under the combined action of magnetic force and gravity, and the gangue mixed in it The upward movement is caused by the rising water flow, and the magnetic agglomeration is subjected to multiple panning during the downward movement. The taste is gradually improved. The equipment has been applied in Bengang Nanfen Concentrator and Shantoushan Concentrator, and Jilin Banshigou Concentrator. Northeastern University has successfully developed a pulse vibrating magnetic field magnetic separation column. The device forms a vibrating magnetic field that constantly "moves" from top to bottom in the coil. The combination of a strong "vibration" magnetic field and a strong rising water flow can substantially eliminate magnetic inclusions and greatly increase the grade of iron concentrate. The fine screening of the Benfen Nanfen concentrator in the different current conditions in the laboratory can be selected to improve the grade by 3.54 to 8.27 percentage points. The device has been used in Dandong boron-containing iron ore selection and super Chaoyang factory production of iron ore concentrate. (3) Low field strength self-weight jig After years of research, the development of low-field-strength self-weighting jigs combines magnetoelectricity, jigging and heavy medium dressing. Can be used as a magnetite selection equipment. The 300mm small equipment developed in 2000 was used to improve the iron concentrate grade of the Shougang Water Plant Concentrator. Industrial diversion test results: the ore grade is 62.64%, the concentrate grade is 68.27%, and the operation recovery rate is 91.72%. (4) Low field strength pulsating magnetic separator The low field strength pulsating magnetic separator has the following characteristics: the magnetic system has a large wrap angle. The number of poles is large; the magnetic induction intensity is low, and the distribution from the sweeping area to the concentrate discharge area is unevenly distributed from high to low; and the permanent magnet pulsation device is provided to form a permanent magnetic pulsating magnetic field on the surface of the rotating cylinder to loosen the magnetic Reunion, remove the mixed gangue. The equipment was industrially tested at the Jiugang Concentrator and the Dagushan Concentrator at Anshan Iron and Steel Co., Ltd. The results showed that fine gangue and lean stalks could be better thrown. (5) BX multi-pole magnetic separator The application test of BX multi-pole magnetic separator in Gongchangling Concentrator shows that the concentrate grade of BX magnetic separator is 4.7% higher than that of the original magnetic separator, the grade of tailings is reduced by 0.5%, and the magnetic iron of tailings is reduced by 0.62%. The tailings yield was 12.66%. Industrial test Dagushan, tests showed that upgrading effect is obvious: ore grade of 29.73%, obtained concentrate grade 67.44%, tailings grade 10.25%, 77.27% metal recoveries in metallurgical performance.
