Gypsum Dehydration During Comminution and Its Effect on Cement .
portland cement clinker was ground in plant and laboratory ball mills to examine the effect of grinding in different mills on the cement properties. Mineralogical examination showed that in the plant mill (1200 cm X 260 cm), because of the rising temperature during grinding, gypsum was de- hydrated to hemihydrate, while.
Cement Milling - Understanding Cement
Vertical roller mills (VRMs) are the main alternative means of grinding the clinker and are increasingly being used. See, for example, this page on the FL website (opens in new tab or window). As part of the grinding process, calcium sulfate is added as a set regulator, usually in the form of gypsum (CaSO4.2H2O).
Cement mill - Wikipedia
Blastfurnace slag cement may include up to 70% ground granulated blast furnace slag. See cement. Gypsum and calcium carbonate are relatively soft minerals, and rapidly grind to ultra-fine particles. Grinding aids are typically chemicals added at a rate of 0.01-0.03% that coat the newly formed surfaces of broken mineral.
