Grinding Aids in Cement Production Civil Engineer

The grinding process of cement absorbs 60-70% of the total energy employed. Finish grinding accounts for about 38% of specific electric power consumption. The quantity of energy required by the process to obtain the correct fineness is only partially employed for the creation of new surface: in fact most of the total energy is lost as heat.

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 sieve that is fine enough to hold water.
