High Gradient Magnetic Separator in the application of kaolin ore sorting analysis


High gradient magnetic separation of kaolin in the dyeing impurities (such as hematite, etc.) has a weakly magnetic, so you can take advantage of high gradient magnetic separator to remove it. United States to use PEM -84 type wet high gradient magnetic separator, make the Fe2O3 kaolin ore from 0.9% to 0.6%, Ti2O3 from 1.8% to 2.0% to 0.8%. This high gradient magnetic separator with stainless steel wool for medium field strength of 1.5 ~ 2.0T, the need to power 270 ~ 500kw. Acid mine in Hunan Song Ling Ling, Leiyang, Perot, Heng Leng wet soil were studied, have achieved good results, especially the use of vibrating high gradient magnetic removal of iron titanium kaolin achieved very good The test index. pot magnets  Hunan Leiyang Song Ling Kaolin Mine CLY500 with vibrating high gradient magnetic separator and the United States PEM-84 high-gradient magnetic separator comparative test results, from a drop of iron and titanium impurities, improve the whiteness of view, Song Ling Mine The high gradient magnetic separator performance is better than the United States. Kaolin in some part of the iron ore in the form of impurities in silicates, very weak magnetism, and titanium is in the form of rutile, the magnetic separation is difficult to work, so the process is usually accompanied by flotation, selective flocculation, and other operations to improve product quality. In recent years, the superconducting magnetic separator has been successfully applied kaolin separation, not only to reduce energy consumption, and field strength can greatly improve the quality of higher kaolin concentrate. Eriez superconducting magnetic separator having a rapid rise, and can be designed in the 60s to the highest field strength (5T), and the demagnetization time is short, which greatly reduces the load from the magnet during the cycle time required to flush magnetic impurities. Its low energy consumption than conventional magnetic separator reduced by 80%, the processing capacity of up to 100t / h or more. Magnetic Head Pulley British tested an iterative superconducting magnetic coil system, the design is similar to a conventional pot-shaped magnetic filter, the difference is that during the working cycle it will remain in the excited state of the superconducting magnet, and no switch control, and continuous operation. High gradient magnetic separator Scope: Mainly used in kaolin, senior ball clay, white clay, bentonite, feldspar, albite, Xia feldspar, sericite porcelain stone, pyrophyllite, illite, dolomite, alumina powder , quartz, alumina, wollastonite powder, transparent spodumene powder, lithium feldspar, calcite, raw talc, talc, limestone, fluorite, light calcium nonmetal ore (less than 60 mesh) to wet iron. High gradient magnetic separator with stainless steel wool for medium field strength of 1.5 ~ 2.0T, the need to power 270 ~ 500kw. imanes tierras raras
