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.

Cement is then pumped to silos for storage and dispatch. Mineral additions and SCMs are added to reduce the amount of clinker in cement. This in turn reduces the fuel, power, process emissions and raw materials associated with cement production. At the same time it creates a use for material considered to be a waste product of other industries.
