PTMS magnetic separation

what is magnetic separation method for concentration of ore？

During the use, the magnetic field strength of the iron remover becomes weak. The possibility of this problem in the iron removal machine is that the temperature is too high; the sun is exposed; the acid and alkali corrosion. Specifically, the magnetic field strength of the iron remover can be measured by a Gauss meter. During the working process, the iron removal motor is overheated and its sound is not normal. The abnormality of such iron-removing machine motor overheating and its sound may be caused by poor lubrication or wear of the bearing, or the fan blade falling off or wearing. It may also be considered whether the switch circuit is in poor contact or the single-phase is broken. Caused by the other, too low voltage can also cause similar problems, which is the specific reasons, should be based on the specific analysis of the site of the iron removal machine. The reducer is overheated. The reason that the reducer is overheated may be due to insufficient gear oil or poor oil quality; the gear of the primary reducer is excessively worn or misaligned, or the meshing is not good; the third reason may be that the bearing is poorly lubricated or the wear is severe. The reducer of the iron machine is too hot. Some users also reported that the iron machine was found to be abnormal in operation, the cylinder was stuck by obstacles, and even the cylinder could not be rotated, and the bottom box vibrated. This situation is often caught by the object of the bottom box, and then the magnetic block is detached, causing the cylinder to squeak and severely smash the barrel. At this time, it should be stopped for maintenance and troubleshooting. The magnetic system of the iron removing machine is made of high-quality ferrite material or composited with rare earth magnetic steel. The average magnetic induction intensity of the previous cylinder table is 100-600 mT. At present, due to the development of technology, the iron removal machine can be made into a roll shape, and the magnetic field strength is also increased to 1.3T. It is already the measured magnetic field strength. The iron separator can be sorted with many minerals such as magnetite, limonite, hematite, ilmenite, wolframite, manganese ore, manganese carbonate, manganese oxide, iron ore, kaolin, rare earth ore, etc. Iron machine to choose. The iron removal process is carried out in the magnetic field of the iron remover by means of the action of magnetic force and mechanical force on the ore particles. Different magnetic ore particles move along different trajectories and are sorted into two or more separate beneficiation products. The downstream magnetic separator has a large processing capacity and is suitable for rough selection and selection of coarse-grained ferromagnetic materials, and multiple series work. When the amount of ore is high, the magnetic ore particles are easily lost to the tailings. Therefore, it is necessary to strengthen the operation management and control the lower level of the slurry. The counter-current magnetic separator is suitable for rough selection and sweeping of fine-grained ferromagnetic minerals, and the recovery rate is high. The counter-current magnetic separator can obtain high-quality iron concentrate and also obtain good recovery rate. The countercurrent iron remover has been widely used in production practice.
