core equipment for cement manufacturing. In the fi nal stage of cement manufacturing, the cement clinker that was buffer-stored in the clinker stores is ground to form high-grade cement in an economically effi cient manner. The increasing sub-stitution of cement clinker expands the product ranges of cement manufacturers.
