In the process of iron removal, purification and whitening of kaolin, an electromagnetic slurry iron removal machine is required

The dyeing impurities in kaolin are weakly magnetic, so they can be removed by a high-gradient electromagnetic separator. The electromagnetic high-gradient magnetic separator has been successfully applied to kaolin separation, which not only reduces energy consumption, but also greatly improves the magnetic field strength, and the quality of kaolin concentrate is also high.

Flotation technology can use the separation of kaolin as possible, but the chemical cost is high and the processing cost is high. The electromagnetic high-gradient magnetic separation technology has greatly changed the appearance of the kaolin industry, especially the vibrating high-gradient magnetic separator can effectively remove the iron, titanium and other impurities in the kaolin, and affect the product's particle size composition, physical and chemical properties. Less, can produce high-quality kaolin products. Hard kaolin is suitable for iron removal treatment with electromagnetic dry powder magnetic separator, which can save product dehydration, reduce product loss, and is suitable for dry places with little moisture.

The content of fixed carbon in coal-based kaolin is generally about 2%, and carbon exists in the interstices of kaolin crystals. This kaolin uses high-temperature oxidation sintering method to produce carbon to improve the whiteness of kaolin. Coal-based kaolin must be taken to remove iron and titanium before or during the sintering process to increase the whiteness of the product to more than 90%.
