Portland Cement Manufacturing – Ordinary Portland

Portland cement manufacturing process can be divided into 6 steps: raw material crushing, pre-homogenization, fine grinding, clinker production, cement grinding, cement packing, etc. In these processes, we need the assistance of different kinds of cement equipment, such as cement kilns, cement mills, and cement crushers.
