Once the raw materials have been crushed into raw meal, they are transported to the kiln and Howden fans play an important role in super heating the meal into the cement clinker and then to cool the clinker. The clinker then has gypsum added and is moved into the cement mill to be ground into the final product.

It is more appropriately viewed as a pre-treatment of the raw meal rather than the conversion of the clinker production process. The premise of this option is to calcine the limestone separately from the cement kiln and, in so doing, mitigate the dominant source of CO 2 (66 % including associated fuel) without redesigning the kiln itself.
