Cement Extraction, Processing, Manufacturing Britannica

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 It normally highlights a huge crushing rate and high return and is utilized as an essential equipment in primary, secondary, and tertiary stages of crushing.
