mill process of cement

Cement Production - an overview | ScienceDirect Topics

The production of cement is either through the wet or dry process with the dry process as the preferred option because of the lower energy intensity Cement production accounts for about 5% of total anthropogenic emissions (IFC, 2017) Cement-based structures constitute the largest surface area of all man-made structures (Odigure, 2009)
