Kaolin is a naturally occurring, relatively fine, white clay which may be generally described as a hydrated aluminum silicate. Kaolin clay, after purification and beneficiation, is widely used as a filler and pigment in various materials, such as rubber and resins, and in various coatings, such as paints and coatings for paper.


but also may contain kaolin and montmorillonite. Most domestic clay is mined by open-pit methods using various types of equipment, including draglines, power shovels, front-end loaders, backhoes, scraper-loaders, and shale planers. In addition, some kaolin is extracted by hydraulic mining and dredging. Most underground clay mines are located

Kaolin products are produced from mined Kaolinite (Al 2 Si 2 O 5 (OH) 4), a naturally occurring aluminum silicate deposit.The mined mineral is blunged and degritted than screened for tramp impurities. The recovered Kaolin powder is than milled in attrition mills to produce a uniform powder with a defined particle size (D50) and narrow particle size distribution.


When the dry beneficiation method requires high whiteness of the product, the product produced by Raymond mill must be dry iron removed. The dry process has the advantages of eliminating the dehydration and drying process, reducing the loss of ash powder, short process flow, low production cost, and is suitable for drought and water shortage areas.
