White Cement Manufacturing Process AGICO White

In white cement production, natural gas and heavy oil are the most commonly used fuels in the calcining process. Because they do not contain many colored impurities themselves, using them as fuels could effectively reduce the content of colored impurities in the white cement clinker and improve the whiteness of white cement.
