Capacity of cement new production lines has steadily increased over the last years. Reduction of investment costs is one of the most important driving factors for this trend. Because of simple scalability and low energy consumption, the vertical roller mill is a key part for single mill cement lines.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.
