MTW175 trapezium grinding mill for grinding limestone
Limestone is a collection of minerals, its chemical formula is CaCO3, and the main mineral is calcite. In addition, limestone often contains dolomite, magnesite, and other carbonate minerals, as well as chalcedony, clay, pyrite, marcasite, hydro goethite, glauconite, organic carbon, asphalt, gypsum, anhydrite, and phosphate minerals. The chemical composition of pure limestone is close to the theoretical composition of CaCO3, of which CaO accounts for 56.04% and CO2 accounts for 43.96%.
