What Is the Cement Manufacturing Process? (with pictures)

Grinding is the next step in the cement manufacturing process, and it can occur in either wet or dry forms. Wet grinding involves combining all of the materials in a mill with water and grinding it into slurry. In contrast, dry grinding processes combine and grind the materials without water, creating a substance known as kiln feed.
