RAW MATERIALS IN CEMENT PRODUCTION

Feb 07, 2019 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 Extraction and processing Britannica

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.

Cement History of cement Britannica

Cement - Cement - History of cement: The origin of hydraulic cements goes back to ancient Greece and Rome. The materials used were lime and a volcanic ash that slowly reacted with it in the presence of water to form a hard mass. This formed the cementing material of the Roman mortars and concretes of more than 2,000 years ago and of subsequent construction work in western Europe.
