PPC Cement Manufacturing Process Portland Pozzolana

Portland pozzolana cement shall be manufactured by mixing and inter-grinding Portland cement clinker, pozzolanic materials, and gypsum. The manufacturing process is approximately the same as ordinary Portland cement, which can be divided into four processes: raw material crushing, raw material grinding, clinker calcination, and cement grinding.
