Industrial preparation of cement

The industrial preparation of cement involves several key steps, starting with the extraction and crushing of raw materials, primarily limestone and clay. These materials are then blended and heated in a kiln at high temperatures (around 1400-1600°C) to form clinker, which is subsequently cooled and ground into a fine powder. Gypsum is often added during the grinding process to regulate the setting time of the cement. Finally, the finished product is packaged for distribution and use in construction.
