After the adoption of ultra-fine grinding coal kaolin , calcine process, with many ordinary kaolin do not have the physical and chemical properties , such as high brightness, crystal merciful , porosity, bulk density of small , large surface area , oil absorption , cover resistance and good wear resistance , higher insulation and chemical stability , widely used in paint, paper, rubber , plastics, cables, ceramics and other fields, plays an important role in the modern high-tech industrial development and upgrading of traditional industries .
For performance so good , so versatile product , our country was started in the 1990s , and after the year 1998 has been a series Kaolin standard : dual 90 main point is that the whiteness of ≥ 90%, ≥ fineness -2μm content 90% , this standard is still in use until now , and because the standard for coal kaolin processing technology , there were two controversial processing modes: "After the first grinding burn " and "after the first burning mill ."
Although the two processing modes have their own characteristics , but which is not difficult to find , among the milling equipment in which it is impossible missing . Want to get high fineness of kaolin products , you must use ultrafine mill and some other , more advanced ultra-fine grinding equipment for processing.
