Magnetic separator magnetic separator is one of the most widely used and highly versatile models in the industry. It is used to remove iron powder from powder granules. Magnetic separators are widely used for resource recovery. , mining, kiln, chemical, food and other workshops. The magnetic separator is suitable for wet magnetic separation of magnetite, pyrrhotite, roasting ore, ilmenite and other materials with a particle size of 3mm or less. It is also used for iron removal of coal, non-metallic minerals, building materials and other materials. The magnetic system of the magnetic separator is made of high-quality ferrite material or composited with rare earth magnet steel. The average magnetic induction intensity of the cylinder is 100-600mT.

The magnetic separator can sort a lot of minerals such as: magnetite, limonite, hematite, manganese siderite, ilmenite, wolframite, manganese ore, manganese carbonate ore, metallurgical manganese ore, manganese oxide ore, iron ore, Kaolin, rare earth ore, etc. can be selected by magnetic separator. The magnetic separation process is carried out in the magnetic field of the magnetic separator 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.
According to the type of magnet, it can be divided into: permanent magnet magnetic separator and electromagnetic iron remover.
According to the dry and wet of the mine, it can be divided into: dry iron remover, wet iron remover
According to the magnetic system classification can be divided into: cylinder magnetic separator machine, roller magnetic separator machine and cylinder roller magnetic separator machine.
According to the magnetic coefficient, the classification can be divided into: single cylinder magnetic separator, double cylinder magnetic separator and combined multi-bar magnetic separator.
According to the classification of mining methods, it can be divided into: upper feeding magnetic separator and lower feeding magnetic separator.
According to the classification of magnetic field strength, it can be divided into: weak magnetic separator, medium magnetic separator and strong magnetic separator.
According to the classification of the magnetic system, it can be divided into: an open magnetic magnetic separator, and a magnetic magnetic separator when closed.
The wet type permanent magnetic cylinder magnetic separator is a magnetic separator commonly used in iron ore processing plants, and is suitable for selecting strong magnetic minerals. According to the structure of the tank, the magnetic separator is divided into three types: forward flow, reverse flow and semi-reverse flow. The particle size of the three different tank type magnetic separators is as follows: the downstream tank is ≤6mm, the counterflow tank is ≤1.5mm, and the semi-reverse tank is ≤0.5mm.
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 large, 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 countercurrent magnetic separator is suitable for rough selection and sweeping of fine-grained ferromagnetic minerals, and the recovery rate is high, but the concentrate grade is low. The countercurrent type magnetic separator is not suitable for processing coarse materials because the coarse material is easy to deposit and block the sorting space.
The semi-reverse flow magnetic separator can obtain high-quality iron concentrate and also obtain better recovery rate, so the semi-reverse flow magnetic separator is widely used in production practice. It is suitable for the rough selection and selection of ore particles below 0.5mm, and multiple series and parallel connections for multiple sweeps and selections.
