Raw materials for cement manufacturing

The second important raw material for cement production is clay.The main component of clay is formed by hydrous aluminium silicates.The chemical composition of clay may vary from those close to the pure clay, to that containing a significant amount of admixtures as iron hydroxide, iron sulfide, sand, calcium carbonate, etc. Clay is used as an argillaceous component of raw mix.

Cement Production - an overview | ScienceDirect .

Clinker production. As shown in Fig. 6.6, the feedstock first enters the raw material to make a fine powder (raw feed), where 85% of the material is slightly smaller than 88 μm.Then, the feed is transferred to the homogenizing silos to impair the material difference. After that, the meal is thrown into the precalciner tower to start the chemical change to cement.
