Type IL : Portland Clinker is ground in ball mills together with ~8% gypsum and 1013% raw limestoneto make the finished cement. (gypsum levels need to be optimized) Because limestone is softer than clinker, it grinds preferentially, so the cement needs to be ground finer so the clinker component is of equal fineness to get the same strength
