The value KS K of ordinary Portland cement is 90-95% and 95-98% of high strength Portland cement. The higher value KS K, the lower the grindability. In addition to the physical and chemical characteristics of clinker, the required grinding degree (grinding fineness) also affects grinding balls deterioration.Abstract: For several decades the cement industry has successfully utilized vertical roller mills (VRM) for grinding of raw materials and solid fuels. Most recently, this technology has been employed for the combination of Portland cement, blended cements and slag cements. The VRM offers several benefits compared to the ball mill in regards to operating costs and flexibility.

Chemically modified steel slags, SSM1 and SSM2, were ground in a ball mill to a particle size smaller than 0.075 mm. Those samples were mixed with ordinary Portland cement (OPC–CPV-High Initial Strength) resulting in Portland Slag Cements samples (PSC) in a proportion of 25/75 in mass (modified slag/Portland cement), named PSCM1 and PSCM2.Supercrete, the only Portland Limestone Cement (PLC) brand in Bangladesh, complies with BDS EN 197-1: 2003, CEM II/ B-L, 42.5N standard.
