Kaolin processing plant

Kaolin is a mixture of different minerals. Its main component is kaolinite; in addition, it frequently contains quartz, mica, feldspar, illite, and montmorillonite. Kaolinite is made up of tiny sheets of triclinic crystals with pseudohexagonal morphology. It is formed by rock weathering. It has some cation exchange capacity. The main components of common clay and shale are illite and chlorite.

Kaolin is both dry- and wet-processed. 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. A process flow diagram for kaolin mining and dry processing is presented in Figure 11.25-1, and Figure 11.25-2 illustrates the wet processing of kaolin. 

In the 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 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 process, various chemical methods, such as bleaching, and physical and magnetic methods, may be used to refine the material. Chemical processing includes leaching with sulfuric acid, followed by the addition of a strong reducing agent such as hydrosulfite. Before drying, the slurry is filtered and dewatered by means of a filter press, centrifuge, rotary vacuum filter, or tube filter. The filtered dewatered slurry material may be shipped or further processed by drying in apron, rotary, or spray dryers. Following the drying step, the kaolin may be calcined for use as filler or refractory material. Multiple hearth furnaces are most often used to calcine kaolin. Flash and rotary calciners also are used.

In the kaolin mining process, crushing is the first stage. Using the crushing machine, get kaolin particle, then using the grinding plant with one type of kaolin mill, get kaolin powder. Kaolin clay is formed from the weathering of silica rich rocks such as granite, it occurs with feldspar and quartz. Clay is separated from the other constituents by washing and the slurry is then centrifuged to remove 75% of the minus 0.002mm fraction.

The kaolin processing plant manufactured by Vipeak Machinery starts from kaolin crushing to kaolin powder pulverizing through conveying and screening.

The kaolin particle is not the finished products, what we need is kaolin powder. Usually the powder is 100-800 mesh, 1250 mesh, and 4000 mesh. In order to get them, we need use kaolin mill to grind kaolin particle into powder.

There are several types of kaolin mill used in kaolin grinding process.

Ball mill for kaolin is the common grinding mill in kaolin production line, it is used for coarse grinding, the finished size is 0.074-0.4 mm, the capacity is larger than other kaolin grinding mill.

Raymond mill is another common kaolin mill, the finished particles have a good uniformity of finess, with passing screen rate as high as 98%.
