Get Price2015-3-26 The change is that the specification adds up to 5% limestone. The biggest difference in production is that the limestone is added to the clinker blend before grinding. Because the limestone is softer than the clinker it will grind preferentially, resulting in a cement with a better particle size distribution with less energy.

In the first stage of making cement, limestone and clay are crushed together to form a powder. This powder is then combined in a mixer before passing into a rotating heater which has constant heat applied at one end of the tube.
