Kaolin Wet-Processing - Helals

The second process used to produce kaolins is much more complex and is called the wet process. The kaolin is dispersed in water after it is mined. The first step after dispersion is the removal of the coarse grit ( > 44 µ) by settling procedures and vibrating screens. The resultant degritted slurry is fed into centrifuges to separate the kaolin into fine, intermediate, and coarse particle size fractions. These …
