Clinker is extracted from our clinker tank and transported to the cement mill hopper by belt conveyors. A measured quantity of clinker and gypsum is fed into our closed-circuit ball mill which incorporates with a high-efficiency separator. OPC is produced by the inter-grinding and blending of 95% clinker with 5% gypsum to a fineness of 280 m 2 /kg.
