Raw materials used for Cement Production -

The other important raw material for cement manufacture is clay. Clay is formed by the weathering of alkali and alkaline earth containing aluminum sili­cates and of their chemical conversion products, mainly feldspar and mica. The main component of clays is formed by hydrous aluminum silicates.

Cement Production Cement Howden

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.
