  • The Cement Manufacturing Process

    2015 8 20 In this process the chemical bonds of the raw materials are broken down and then they are recombined into new compounds The result is called clinker which are rounded nodules between 1mm and 25mm across The clinker is ground to a fine powder in a cement mill and mixed with gypsum to create cement.
