Step 6 : Finish Grinding. The clinker is ground in a ball mill—a horizontal steel tube filled with steel balls. As the tube rotates the steel balls tumble and crush the clinker into a super-fine powder. It can now be considered Portland cement. The cement is so fine it will easily pass through a
The clinker is then ground to produce portland cement. Gypsum is added during the grinding process to control the set rate of the cement. Slag and fly ash can also be added to control other properties of the final product. Both the dry and wet processes are very energy intensive.
