The only common feature in all cement production plants is the difficulty of grinding the source material as the material is hard enough and has high abrasiveness. That is why high quality grinding balls with high hardness over the entire section are used during grinding materials in tube mills in this industry.
Cement Cement 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.
