Ceramic raw material composition is very much, natural raw materials based on the complex mineralization environment, often containing quartz, feldspar, iron and other impurities, these substances have a direct impact on the quality of ceramic products, so before use, to go through the process of iron removal.
At present, the methods of iron removal and whitening include physical method, chemical method and biological method.The physical method is divided into water washing method, magnetic separation method and flotation method.The water washing method can separate different dissolved substances by water.Magnetic separation method is based on the different mineralogy, different minerals in the magnetic field under different forces, thus separation.Flotation is a method to separate ore by the difference of physical and chemical properties of mineral surface.The magnetic separation method and flotation method have better effect on improving the whiteness, while the magnetic separation method is widely used.
The high gradient magnetic separation method has high yield and is beneficial to mechanized production.Through the research and development of professional r & d personnel, guote equipment has designed a series of vertical ring high gradient magnetic separator and permanent high gradient magnetic separator, which have remarkable effects on the application of washed kaolin mineral processing and have been well received by many users.
