In actual operation, the magnetic separator for coarse, medium and fine particles has a certain range requirements, while these different tablets to achieve the magnetic effect is not the same, in order to better achieve suitable for high gradient magnetic within the range of magnetic sorting machine, we must work on the grinding material particles were required magnetic separator magnetic field lines are always closed curve. Perfect advantage of professional applications laboratory magnetic separator equipment, we have chosen the standard separator: magnetic height, penetration, feed grade level, to mine the thickness of the particle size distribution than to mine humidity. We all know that after the magnetic material into the magnetic field, the size of the force depends on the size of the magnetic field strength at that point, but the size of the magnetic field strength depends not only on the level of dry magnetic drum, also with the magnetic field gradient at this point is closely relationship. However, due to the lack of the whole machinery manufacturing strong manufacturing base, and therefore look at the current state of development of mineral processing equipment manufacturing industry, we find that there are still many problems in the magnetic separator magnetic system design, processing equipment manufacturers gradually high gradient magnetic separator magnetic minerals in the field of precision sorting increasingly demanding, but also for the fine piece of equipment designed separator more emphasis, drum magnetic separator used in mining, coal preparation plant and other units, fine design separator device components. Currently limonite iron ore beneficiation equipment separator mirror dressing Plant adopts a weak magnetic iron oxide - magnetic - reverse flotation process was the election of iron, its magnetic concentrate in class mainly buoyant fluorite, carbon salt and other minerals and hard floating refractory iron silicate minerals. Under the conditions selected size 82-75μm percent of dry magnetic separator, made of SiO2 + impurities Al2O dropped by more than 11% below 6%, iron ore grade increased by 55% to 59% or more (after burning iron grade of 60% or more), a good indicator of lower miscellaneous jobs recovery rate of 94%. Refractory metals symbiosis of multi-Bayan Obo iron ore mainly Baotou Rare Earth Panzhihua Iron and vanadium-titanium magnetite, limonite iron ore beneficiation equipment mirror magnetic separator is characterized by the type of iron ore mineral composition and symbiotic relationship complex, the resulting low iron ore sorting index and valuable elements were associated with low recoveries. Among Baotou Bayan Obo rare earth oxide ore is particularly difficult choice.
