Process for the preparation of Portland cement clinker

A process for the preparation of Portland cement clinker resides in that limey, clayey and iron-containing components are ground together. The mix is then homogeneized pelletized, decarbonized at 800° to 1000° C. and roasted at 1200° to 1350° C. Dust sublimates--wastes of the titanium production--are added at the stage of grinding or homogeneization in an amount of 0.5 to 6.0% by total

Manufacturing Process Continental Cement

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.
