Kaolinite is a kind of silicate minerals containing hydroxyl. Kaolinite is of mosh hardness 2-2.5 and the proportion of 2.6-2.63.
As a kind of clay mineral, kaolinite always exists with microcrystalline or cryptocrystalline state, and is produced with dense block or earthy collection (the latter is often called kaolin). Pure kaolinite is of white, and those with various impurities is often of different colors, such as those containing organic matter is of black and brown due to iron staining, etc.
 

Kaolinite is the product of low-temperature hydrothermal alteration of aluminum silicates such as feldspar and mica and secondary weathering and is very widespread. In the ceramic industry, paper, rubber, electronics and other industries, kaolinite is the important raw material.
 

Kaolinite is the major mineral of Kaolin, common in the weathering crust of igneous rocks and metamorphic rocks. China is the famous place of kaolinite origin. Apart from China, the world famous origin of kaolinite mine is the United Kingdom, France, the United States, and so on.
 

Kaolin clay formed after kaolinite being weathered or deposited is commonly known as "clay" , composited with more than 90% content of kaolinite. Kaolin is an important non-metallic mineral, and the kaolin plus mica, quartz, calcium carbonate is called the four major non-metallic minerals. Kaolin is the raw materials for the ceramic production. In addition, the kaolin can be used widely as chemical filler, refractory materials, building materials, etc.

For kaolinite quarry or kaolinite mining, choosing the right kaolinite crusher and grinding machine is important in the whole kaolin crushing plant.
Take the jaw crusher for example. Jaw crusher is usually used kaolinite primary crushing equipment. With simple structure and big crushing ratio, jaw crusher is widely applied for kaolinite mining.
For kaolin grinding, you can choose coal mill or coarse powder grinding mill. Since both the grinding machines are designed under the test of success crushing, you can improve your grinding efficiency greatly.
