zhengzhou, China (prHWY.com) April 25, 2012 - The term 'kaolin' is derived from kaoling (meaning 'high hill' in Chinese), a village in Jingdezhen City, Jiangxi Province, China, where kaolins were first discovered. Kaolin ore is clay (or claystone) in which the content of the kaolinite-subgroup clay minerals attains the usable content. According to the quality, plasticity and sand content, koalin ore may be divided into hard kaolin, soft kaolin and sandy kaolin. For kaolins derived from weathering in southern China, those that are earthy in shape and occur in the upper part of a weathering zone are called porcelain clay by the local people and those that are hard and massive and occur in a semi-weathering zone are called procelain stone.

As kaolin has many good technological properties, it is widely used in the manufacture of ceramics, refractories, rubber, paper, plastics, chemicals, agricultural chemicals, drugs and textiles, as well as the petroleum, building material and national defence industries. With the development of industrial technology and improvement of scientific and technological levels, there are more and more types of ceramic products. In addition to daily ceramics, architectural and sanilary ceramics and electric porcelain that consume large amounts of kaolin, new and high technology fields, such as the national defence industry, also require new types of ceramic products. Kaolin has been used more and more widely.As the professional manufacturer of complete sets of mining machinery, such as rotary dryers,sand maker, Henan Hongxing is always doing the best in products and service.limestone rotary kiln:http://www.hxjq-crusher.com/23.html.ore separating line:http://www.hxjqchina.com/.

China was the first country that used kaolin in the manufacture of ceramics. The unearthed artifact-press marked pottery-of the Shang Dynasty (c. 17th~11th century B.C.) was made out of kaolin, and as early as the Yuan Dynasty (1206~1368) the Jingdezhen porcelain was renowned in China and abroad. At the beginning of the 20th century, Liling of Hunan Province, Tangshan of Hebei Province, Dehua of Fujian Province and Shiwan of Guangdong Province all attached importance to kaolin production while developing the ceramic industry. In 1926 kaolin in the Yangshan kaolin deposit, Suzhou, Jiangsu, was mined for use in the making of refractories. Since 1949, kaolin production in China has developed rapidly. Six major kaolin-producing areas, namely, Jiangsu, Hunan, Jiangxi, Guangdong, Fujian and Shanxi, have been taking shape gradually and small-scale mining has also been carried out in more than ten other provinces (autonomous regions). Up to 1997 there were over 100 state-owned mines and over 700 village- and township-owned mines.
