magnetic separator can be used for wet dressing ores with sizes less than 3mm .such as magnetite.pyrrhotite,calcined ore;ilmenite and so on.It is also used to remove the iron for processing coal.non-metallic minerals and construction materials The magnetic system of the magnetic separator is made by compositive materials of high quality ferrite materials and rare earth magnetic steel the magnetic induction intensity can reach 100-600mt. According to user needs Can provide downstream, semi-reflux, reflux-type and so manydifferent form strong magnetic separation. This magnetic separator has the advantage of high capacity easy to cont rol and Simple structure.
2.Applications
The raw bauxite ore contains 1.69% Fe2O3, the magnetic separation concentrate contains 0.23% Fe2O3, and the yield is 80%.The raw ore of coal series kaolin mine contains Fe2O3 0.85%, and the magnetic separation concentrate contains 0.44% Fe2O3, with a yield rate of 89%. Introduction to the classification of magnetic separator There are many minerals that can be separated by magnetic separators, such as magnetite, limonite, hematite, manganese siderite, ilmenite, wolframite, manganese ore, manganese carbonate ore, metallurgical manganese ore, manganese oxide ore, iron sand ore, Kaolin, rare earth ore, etc. can be separated by a magnetic separator. The magnetic separation process is carried out in the magnetic field of the magnetic separator with the help of the action of magnetic and mechanical forces on the ore particles. Different magnetic ore particles move along different trajectories and are sorted into two or more separate beneficiation products.
3.Classification According to the type of magnet, it can be divided into: permanent magnet magnetic separator and electromagnetic iron remover According to the dryness and wetness of the mine, it can be divided into: dry iron remover, wet iron remover According to the magnetic system, it can be divided into: drum magnetic separator, roller magnetic separator, drum magnetic separator and flat magnetic separator. According to the magnetic coefficient, it can be classified into: single-tube magnetic separator, double-tube magnetic separator and combined multi-tube magnetic separator. According to the ore feeding method, it can be divided into: the upper feeding magnetic separator and the lower feeding magnetic separator. According to the classification of magnetic field intensity, 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: open magnetic circuit magnetic separator, magnetic circuit magnetic separator when closed. The wet permanent magnetic cylinder magnetic separator is a kind of magnetic separator commonly used in iron ore concentrators, and it is suitable for separating strong magnetic minerals. According to the different structure of the tank, the magnetic separator is divided into three types: forward flow, counter flow, and semi-counter flow. The selected particle sizes of three different tank types of magnetic separators are as follows: downstream tank ≤6mm, countercurrent tank ≤1.5mm, and semi-countercurrent tank ≤0.5mm. The downstream magnetic separator has a large processing capacity, which is suitable for the rough selection and selection of relatively coarse-grained and strong magnetic materials, and it can also work in series. When the downstream magnetic separator feeds a large amount of ore, the magnetic ore particles are easily lost to the tailings. Therefore, it is necessary to strengthen the operation management and control the lower slurry level. The countercurrent magnetic separator is suitable for the rough separation and sweeping of fine-grained strong magnetic minerals. The recovery rate is high, but the concentrate grade is low. Because coarse-grained materials are easy to deposit and block the separation space, the countercurrent magnetic separator is not suitable for processing coarse-grained materials. The semi-countercurrent magnetic separator can obtain high-quality iron concentrates, and at the same time, it can also obtain a better recovery rate, so the semi-countercurrent magnetic separator has been widely used in production practice. It is suitable for rough selection and beneficiation of ore particles smaller than 0.5mm, and multiple units can be connected in series and parallel to realize multiple sweep selection and beneficiation.
