Demands and supplies ratio of kaolin products
In recent years, ceramic-grade kaolin products have been more than self-sufficient in China. Although the exports increase somewhat, a small amount is still kept in stock and paper coating-grade kaolin cannot meet the demand and needed to be imported. Now the construction of concentrated dressing factories is being accelerated in Guangdong, Fujian, Jiangsu, Hunan and Henan. Once these dressing factories are built, paper coating-grade kaolin can not only meet the domestic demand but some of it can also be exported. According to the prediction, the world demand of kaolin will grow steadily and the production of kaolin will increase at the same time. Looking forward to the future, the kaolin market will face keen competition from white minerals such as calcium carbonate, talc and gypsum. Moreover, the consumption of papermaking-grade kaolin will be threatened by the development of new technologies; for example, the appearance of chemimechanical pulp, application of recycled paper and problems of world-wide steadily sound environmental protection all may result in the decrease of the consumption of papermaking-group kaolin. Furthermore, the use of kaolin in ceramics, refractories, building materials, coating materials, rubber, plastics, chemicals and agricultural chemicals will increase slowly. It is estimated that the kaolin consumption in the above fields will account for about 15% of the total kaolin consumption.
The consumption of kaolin in China will change from traditional ceramics and ordinary refractories to the papermaking industry. At present China’s papermaking industry is increasing at a rate of 9.6% each year, but the average per capita consumption of paper is only 17 kg, far lower than the annual average per capita consumption (44.8 kg) of the world and that (19.8 kg) of Asia. Kaolin used for papermaking accounts for 8 to 10% of the materials for this purpose. So the market of kaolin used for papermaking in China has great potential. It is estimated that by 2000 the kaolin consumption will increase to 1.50 millions tons, including 300,000 tons for knife coating-grade kaolin, 650,000 tons for the electric porcelain industry, 150,000 tons for the rubber industry and 70,000 tons for the petroleum industry.As the professional manufacturer of complete sets of mining machinery, such as stone crushing plant,stone crushing plant, 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/.
Kaolin resources of China have great potential. Besides retained reserves, Carboniferous to Jurassic and Tertiary coal measures also contain abundant sedimentary kaolin. According to the statistics, in the Dongsheng coal field of Inner Mongolia, one ton of kaolin can be recovered from two to three tons of raw kaolin, whereas at Maomin of Guangdong the recovery of one ton of kaolin requires five to six tons of raw kaolin. So the development of coal-measures kaolin has good prospects.
The world kaolin market will keep a development trend in several years, and the production of kaolin, especially high-duty kaolin, will grow progressively. Therefore, we should fix our attention on both the domestic and foreign markets, integrate abundant resources with introduction of foreign funds and technology, be based on intensive processing and develop new products to turn China’s kaolin industry into an industry that can both meet the domestic demand and earn foreign currency through export.
