Kaolin is a general term for a family of clay minerals, consisting essentially of a group of kaolinite and halloysite group, mainly composed of kaolinite, halloysite content up to 90%, followed by hydromica often mixedpyrite, limonite, anatase, quartz, chalcedony, alum, and sometimes a small amount of organic matter. Kaolin has excellent process characteristics of plasticity, adhesion, sintering and fire resistance, it is widely used in ceramics, paper, rubber, plastics and refractory industries. Genetic types of kaolin deposits mainly three categories: weathering, sedimentary and hydrothermal alteration type.

Kaolin ore processing depends on the nature of the ore and the end use of the product. Application in the industrial production process, there are two: the dry process and the wet process production of dry, usually hard kaolin, soft kaolin wet production. Dry beneficiation process dry process is a simple and economical process. Mined ore passes through hammer crusher broken to 25.4mm, to into the cage crusher, particle size reduction to 6.35mm hot air inside the cage crusher kaolin water dropped from 20% of the mined about 10%. Broken ore with centrifuge with a blower and cyclone Raymond ground. The process can remove most of the sand and gravel products are usually cheap filler for rubber, plastics and paper industry. For the paper industry, the product can be used as a filler filler layer ash content of less than 10% or 12% at the brightness less demanding. When dry whiteness products require a higher for Raymond output products dry in addition to iron. The advantages of dry process eliminates the need for dehydration and dry operation of the process, to reduce the loss of ash, short process, low production cost and suitable for arid and water-scarce areas. But to get the high-purity quality kaolin have to rely on the wet process.
