Grinding clinker and gypsum produces ordinary Portland cement (OPC). Fly ash / Slag at required proportion is ground along with clinker and gypsum to produce Portland pozzolana cement (PPC) / Portland slag cement (PSC). The ground cement is stored in concrete silos and packed in 50 Kg bags using electronic packing machines.
