Calcium carbonate is an inorganic compound is the main component of limestone and calcite. Calcium carbonate is mainly used for test and measuring organic halogen compounds in the reaction, together with the decomposition of ammonium chloride silicate, calcium chloride solution was prepared to standardized soap, water analysis, test phosphorus, manufacture of optical neodymium glass raw materials. Jaw crusher, impact crusher, CS series cone crusher and vertical mill, high pressure mill, ultrafine mill is a very good crushing equipment and milling equipment, crushing and milling of calcium carbonate in terms of It has a good application and effects. China Calcium Carbonate resource profile and geographical distribution China is rich in limestone mineral resources one of the world countries. According to the former National Building Materials Bureau of Geology Center, National Limestone area of 438,000 KM2 (in addition to Shanghai, Hong Kong and Macao, in the provinces, municipalities and autonomous regions are distributed), which can supply the raw materials to make cement limestone resources about the total resource 1/4 to 1/3. In order to meet environmental protection, ecological balance, and the need to prevent soil erosion, tourism and other aspects of the landscape, especially with the construction of small towns planning and implementation of continuous improvement, exploitation of limestone for cement will also be reduced.
