Cement milling and gypsum dehydration. Because the cement gets hot due to the heat generated by grinding, gypsum can be partly dehydrated, forming hemihydrate, or plaster of Paris - 2CaSO 4.H 2 O. On further heating, hemihydrate dehydrates further to a form of calcium sulfate known as soluble anhydrite (~CaSO 4). This is calcium sulfate with a ...

Demand for cement in the construction industry drives production, and thus it is an important determinant of cement subsector energy consumption and CO 2 emissions. Initial estimates suggest that cement production returned to 4.1 gigatonnes (Gt) globally in 2018, a 1% increase following annual declines of 1% during 2014‑17.

When it comes to achieving the best energy consumption, what are the key factors a cement producer needs to address? In this article, extracted from the newly published Cement Plant Environmental Handbook (Second Edition), Lawrie Evans presents a masterclass in understanding and optimising cement plant energy consumption.
