The high-gradient strong magnetic separator is a swivel vertical rotary magnetic separator, which is suitable for the beneficiation of weakly magnetic minerals, iron removal and purification of non-metallic ores. Such as: hematite, limonite, siderite, imenite, chromite, wolframite, tantalum niobium, red mud, etc. Iron removal and purification of non-metallic minerals. For example: quarz, feldspar, nepheline, fluorite, sillimanite, spodumene, kaolin, etc. The highgradient magnetic separator is suitable for wet magnetic separation of magnetite, pyrrhotte, roasted ore, ilmenite and other materials with a particle size of less than 3mm, and is also used for iron removal of coal, non-metallic ores, building materials and other materials.
