Dry Magnetic Separator is one kind of high-efficiency ore dressing equipments for processing fine, feebly magnetic minerals, such as hematite, limonite, wolfram, limonite, and tantalum-niobium, etc. In recent years, it is also more and more applied in purifying quartz, feldspar and nephrite. It is available in cyclic design with process vessel diameters smaller than 3mm , and can separate raw materials with different magnetic rigidities.Its magnetic system is a ring-shape chain closed magnetic circuit with energizing coils made of copper tube and cooled internally by water. Grooved plates made of magnetic conductive stainless steel are used as magnetic matrix. So it may be widely used in metallurgical mines and other industries.
