Water Cooling Electromagnetic Separator
First of all, calcined kaolin is calcined, and the crystal form and original soil have been changed. Washed kaolin is only a physical treatment and will not change the nature of the original soil. Secondly, the difference of whiteness is relatively large. Generally, the whiteness of kaolin will increase after light burning, while washing will not significantly increase the whiteness. PTMS magnetic separator can improve the whiteness of products.

Third, different uses. According to different calcination temperature, kaolin can be used as paper additive and refractory aggregate. PTMS magnetic separator can improve the whiteness of products. Washed kaolin is generally used as papermaking filler.

What Is Magnetic Separation Process ?
Moreover, calcined kaolin mainly refers to hard kaolin (coal series kaolin) at present. The original soil has no bonding property and can not be directly used as raw materials for papermaking or refractory materials. It needs to be applied after calcination. The original soil of washed kaolin has the bonding property and can be directly used as a refractory binder or papermaking filler. PTMS magnetic separator can improve the whiteness of products. As a paper filler, the whiteness of calcined kaolin is much better, and the cost is higher.
