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.

and alumina. Finished cement is produced by finely grinding together around 95% cement clinker with 5% gypsum (or anhydrite) which helps to retard the setting time of the cement. The quality of cement clinker is directly related to the chemistry of the raw materials used. Around 80–90% of raw material for the kiln feed is limestone.
