The beneficiation processing of kaolin is divided into two processes: dry process and wet process.

Dry Process: the mined ore is broken by the crusher to about 25 mm, then fed into the cage crusher to reduce its particle size to about 6 mm. The crushed ore is further ground by a blown-type raymond mill equipped with a centrifugal separator and a cyclone. The process can remove most of the sand and is suitable for processing ore with high whiteness, low sandstone content and suitable particle size distribution. Dry processing has the advantages of low cost, and products are often used in low-cost fillers in industries such as rubber, plastics and paper.

Wet Process: generally breaks the ore, and then passes through the slurry, sand removal, cyclone classification, stripping, centrifuge classification, magnetic separation (or bleaching), concentration, pressure filtration, and drying. The product thus obtained can be used for the ceramic or paper coatings. If preparing filler grade or paper coating grade kaolin, you need to increase the calcination process before crushing step.
