FOR PORTLANDLIMESTONE CEMENT Limestone is much easier to grind than clinker. The common intergrinding of limestone and clinker in classical ball mills is therefore producing a cement of very high surface. The higher the limestone content, the higher the negative impact of its surface on water demand and powder flowability. The intergrinding ...
