Sep 16, 2020 When envisioning the cement plant of the future, it is important to understand the reference for a typical plant today. Our reference plant is a five-stage preheater-calciner kiln with a vertical raw mill and two cement ball mills. It has an annual production capacity of one million metric tons of cement and produces several types of cement.
The clinker is ground in a ball milla 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.
