Extraction and processing. Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can be dug directly by excavators.. The …

Once the dry ingredients are mixed post crushing, a small amount of water is added to the mix to supplement the moisture content to about 14%. Consequently, the addition of water propels the cohesion process and small lumps begin to form. The cake-like lumps are dried and fed to a rotary kiln, where they are subjected to a very high temperature.
