It is clearly helpful, therefore, if the clinker is cool as it enters the mill. From an environmental and a cost viewpoint, the cooler reduces energy consumption by extracting heat from the clinker, enabling it to be used to heat the raw materials. From a cement performance viewpoint, faster cooling of the clinker enhances silicate reactivity.
