Cement production is an energy-intensive process due to the high temperatures required to produce clinker in a kiln but also due to the chemical reactions happening during pyroprocessing. The process of creating clinker involves heating a mixture of raw materials to extremely high temperatures, typically around 1400-1500°C, which requires significant

PROCESSES AND TECHNOLOGY STATUS – The manufacture of cement is a two-phase process. Clinker is first produced in a kiln system from calcareous (limestone, chalk or marl) and argillaceous (clay or shale) materials, with addition, in some cases, of small amounts of corrective materials (sand, waste bauxite, iron ore).
