A typical raw mix consists of 75-85% limestone, 12-25% shale, the balance consisting of silica or quartzite and iron oxide. Exact proportioning is dependent upon their chemical properties before and after calcining to cement clinker. For good kiln practice the grind required is 88-92% – 200 mesh for standard cement, 99%-200 mesh for high early.
Here, process and quality must always be dead-on. Optimized plant performance and perfect process control are indispensable. Cement mills are the biggest consumers of electrical energy. Good grinding organization and intense monitoring can keep grinding cost under control. Regarding cement grinding, the focus is on the following topics:
The clinker from the pyro-processing area is ground in ball mills or roll press + Ball mill combination or vertical roller mills to form cement. Commonly used separators are in closed circuit grinding are: O –sepa, Sepol and Sepax separators to achieve a finish cement fineness of 3000 – 4000 Blaine surface (cm2/gm).
