2021-11-1 Burning of clinker is the most influencing step of cement quality during the production process. Appropriate characterization for quality control and decision making is therefore the critical point to maintain a stable production but also for the development of alternative cements.
2021-12-1 Sintering: Sintering is the process of compacting and forming a solid mass of material by heat or pressure to the point of liquefaction without actually melting it. When the temperature inside the kiln reaches about 1300°C (the eutectic melting point of aluminate, ferrite and silicate), clinker flux is
2021-3-4 Due to the high demand for thermal energy and the nature of the clinker production process, electrical emissions from cement plants can often be sidelined. However, the CO 2 emissions associated with power generation still account for around 10-15% of the overall total. Minimising this is thus essential for producers seeking net-zero CO 2
