Clays Statistics and Information | U.S. Geological Survey
Six types of clays are mined in the United States: ball clay, bentonite, common clay, fire clay, fuller's earth, and kaolin. Mineral composition, plasticity, color, absorption qualities, firing characteristics, and clarification properties are a few of the characteristics used to distinguish between the different clay types.

Kaolinite Processing | Equipment, Process Flow, Cases
The kaolinite dry mining process is a simple and economical process. The ore is crushed to 25.4mm by a hammer crusher and fed into the cage mill to reduce the particle size to 6.35mm. The hot air in the cage mill reduces the moisture of the kaolin from about 20% to 10%. The crushed ore is further ground by a blown-type Raymond mill …
