The heat for drying is typically is supplied by waste gases from the rotary kiln or clinker cooler. For grinding, large cement plants use high speed roller mills or bowl type grinding mills, and smaller plants use tube mills packed with paper bags filled with iron grinding balls.

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 superfine 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.

5. Cement grinding. At the cement mills the clinker is mixed with other additives required for producing the specific type of cement. Gypsum for OPC, limestone for limestone cement, and slag for slag cement. The ball mill then grinds the feed to a fine powder. The fine powder is then sent to a separator which separates fine and coarse product.
