Module 4: Cement Grinding Systems and Dispatch. Cement clinker is grinding in roller mills and ball mills, such as granulated blast furnace slag, fly ash, limestone, and approximately 5% sulfate agents (e.g., gypsum). During production and before leaving the plant, the cement is internally inspected and tested in the plant's laboratories.
