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.
o < 20% of energy absorbed is reckoned to be converted to useful grinding: the bulk is lost as heat, noise, equipment wear & vibration; o For ball mills, only 3 – 6% of absorbed energy is utilized in surface production, the heat generated can increase mill temperature to > 120⁰ C & causes excessive gypsum dehydration & media coating if mill ventilation is …
