Cement Manufacturing. Industry Description and Practices. The preparation of cement involves mining; crushing, and grinding of raw materials (princi. pally limestone and clay); calcining the materi. als in a rotary kiln; cooling the resulting clinker; mixing the clinker with gypsum; and milling, storing, and bagging the finished cement.

Portland cement manufacturing is a large scale process. The quality of the final manufactured cement depends upon the proportion of the ingredient and maintaining proper process parameters. To ensure the end quality, a strict quality check is maintained throughout the entire Portland cement manufacturing process. Related Readings
