Kaolin Clay Beneficiation Plant

The kaolin clay plants are kaolin, ball clay, fire clay, bentonite, fuller’s earth, and common clay and shale. Kaolin, or china clay, is defined as a white, claylike material composed mainly of kaolinite, which is a hydrated aluminum silicate, and other kaolin-group minerals. Kaolin has a wide variety of industrial applications including paper coating and filling, refractories, fiberglass and insulation, rubber, paint,ceramics, and chemicals.

Kaolin Clay Beneficiation Plant

Kaolin Clays usually are transported by truck from the mine to the processing plants, many of which are located at or near the mine. For most applications, clays are processed by mechanical methods, such as crushing, grinding, and screening, that do not appreciably alter the chemical or mineralogical properties of the material. The dry process is simpler and produces a lower quality product than the wet process. Dry-processed kaolin is used mainly in the rubber industry, and to a lesser extent, for paper filling and to produce fiberglass and sanitary ware.

Wet-processed kaolin is used extensively in the paper manufacturing industry.Zenith Machinery Kaolin Clay Beneficiation Plants are exported to Chile,Libya, ,Philippines, Angola, Tajikistan ,Dubai ,Brazilon,Peru ,Mexico,South Africa,Kenya,Algeria ,Eygpt,Ghana ,Zimbabwe, Sri Lanka ,UAE,India , Nigeria, Australia ,Saudi Arabia,Indonesia, Pakistan ,Germany,Bangladesh ,America, ,Iran,Malaysia ,Turkey,Italy, Singpore

Kaolin Clay Manufacturing Process

In the kaolin dry process, the raw material is crushed to the desired size, dried in rotary dryers, pulverized and air-floated to remove most of the coarse grit. Wet processing of kaolin clay begins with blunging to produce a slurry, which then is fractionated into coarse and fine fractions using centrifuges, hydrocyclones, or hydroseparators. At this step in the kaolin clay process, various chemical methods, such as bleaching, and physical and magnetic methods, may be used to refine the material. Chemical kaolin clay ore processing includes leaching with sulfuric acid, followed by the addition of a strong reducing agent such as hydrosulfite.
