Cement - Extraction, Processing, Manufacturing: 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 …
The most common way to manufacture Portland cement is through a dry process. The first step is to quarry the principal raw materials, mainly limestone, clay, and other materials.
Manufacturing process of Cement The production process for cement consists of drying, grinding and mixing limestone and additives like bauxite and iron ore into a powder known as "raw meal". The raw meal is then heated and burned in a pre-heater and kiln and then cooled in an air cooling system to form a semi-finished product, known as a ...
