Raw Material Requirement in White Cement Production

Only by strictly limiting the content of Fe 2 O 3 in raw materials and fuels can we meet the production requirements of white cement. Therefore, white cement plants often use high-quality limestone as raw materials and mix with silica raw materials such as pyrophyllite, feldspar, silica, kaolinite, and quartz sand to produce white cement.
