Cement manufacturing process

Cement manufacturing begins with extracting raw materials like limestone and clay from quarries. These materials are crushed and heated in a kiln to about 1450°C, where they undergo chemical transformations to form clinker—a granular substance. The clinker is cooled and ground into fine powder, with small amounts of gypsum added to control setting time. This powder, called cement, is then stored and shipped for use in construction. The process involves quarrying, blending, heating, cooling, grinding, and mixing, all designed to produce a durable binder essential for concrete and mortar.
