Guide: 23. Utilization of composite polyurethane adhesive in 2011, the import volume of kaolin and similar soils in China was 361800 tons, an increase of 5.1% year-on-year; The import amount reached US $97.4447 million, an increase of 15.6% year-on-year. In the first 10 months of 2011, China exported a total of 969800 tons of kaolin and similar soils, with a year-on-year increase of 9.0%; The export amount reached 84.5348 million

in 2011, the import volume of kaolin and similar soils in China was 361800 tons, with a year-on-year increase of 5.1%; The import amount reached US $97.4447 million, an increase of 15.6% year-on-year. In the first 10 months of 2011, China exported a total of 969800 tons of kaolin and similar soils, with a year-on-year increase of 9.0%; The export amount reached US $84.5348 million, a year-on-year increase of 20.3%

at present, there are more than 700 kaolin ore spots in China, and the proved reserves of 200 ore spots are 3 billion tons, and the ore spots are relatively scattered. Among them, coal measure kaolin is 1.67 billion tons, which is mainly distributed in the Carboniferous Permian coal measures in the northeast and northwest of northern China, and exists in the form of gangues in coal seams, roof and floor or separate seams

pure kaolin has high whiteness, soft quality, easy to disperse and suspend in water, good plasticity and high adhesion, and excellent electrical insulation performance, which preliminarily establishes a new material classification system; It has good acid solubility, low cation exchange capacity, good fire resistance and other physical and chemical properties. Therefore, kaolin has become a necessary mineral raw material for dozens of industries such as papermaking, ceramics, rubber, chemical industry, coating, medicine and national defense

it is reported that kaolin is also used in Japan to replace steel in manufacturing cutting tools, lathe bits and internal combustion engine casings. Especially in recent years, the rapid development of modern science and technology has made the application fields of kaolin more extensive. Some high-tech fields have begun to use kaolin in a large number and expand the production scope as soon as possible. Kaolin is used as a new material, and even the high temperature resistant porcelain parts of atomic reactors, space shuttles and spacecraft are also made of kaolin

in order to effectively strengthen the processing and mining of kaolin and increase China's foreign exchange revenue, Shanghai xiazhou heavy industry launched a high-efficiency mill kaolin mill, which adopts the advanced structure of similar products at home and abroad, and is updated and improved on the basis of the mill in the same industry. The kaolin mill is more efficient than the ball mill, with low power consumption, small floor area and small one-time investment. The grinding roll of kaolin mill is tightly rolled on the grinding ring under the action of centrifugal force, so when the grinding roll and ring are worn to a certain thickness, it will not affect the output and fineness of the finished product. The replacement cycle of grinding roller and ring is long, so as to eliminate the disadvantage of short replacement cycle of vulnerable parts of centrifugal crusher. The air flow of this machine circulates in the fan - shell grinding - cyclone separator - fan, so it has less dust than the high-speed centrifugal crusher, and the operation workshop is clean and the environment is pollution-free. The particle size of the finished product milled by xiazhou heavy industry mill is within the range of mesh, and the particle size of the finished product is adjusted as required (the smallest is 1250 mesh)
