Kaolin is a non-metallic mineral, a kind of clay and clay rock mainly composed of kaolinite clay minerals. Pure kaolin is white, delicate, soft and earthy, and has good physical and chemical properties such as plasticity and fire resistance. Its mineral composition is mainly composed of kaolinite, halloysite, hydromica, illite, montmorillonite, quartz, feldspar and other minerals. Kaolin is widely used, mainly used in papermaking, ceramics and refractory materials. Secondly, it is used in coatings, rubber fillers, enamel glazes and white cement raw materials. In small quantities, it is used in plastics, paints, pigments, grinding wheels, pencils, daily cosmetics, soaps, etc. Pesticides, medicines, textiles, petroleum, chemicals, building materials, national defense and other industrial sectors. Guikuang Machinery grinding mill is widely used in the field of kaolin powder equipment and is very popular in the market.
The production process of dry processing and crushing of kaolin is to crush the raw ore to about 5mm, and then further grind it into powder through a Raymond mill equipped with a separator and a dust collector, so that most of the sand and gravel can be removed. This process is mainly suitable for processing ores with high whiteness, low sand and gravel content, and suitable particle size distribution.
