White Cement Manufacturing Process: 6

White cement is a type of special cement, belongs to decoration cement.In general, Portland cement is greyish-green, as the name suggested, white cement is white. In the cement manufacturing process, in order to avoid the mixing of colored impurities, calcination of white cement plant mostly use natural gas or heavy oil as fuel.

White Cement Manufacturing – White Cement Plant

The production process of white Portland cement is quite different from ordinary Portland cement. It is unique in both process flow and cement equipment selection. In white cement plants, the main manufacturing process includes six steps: raw material crushing, raw material grinding, clinker calcination, clinker cooling, cement grinding, and cement packing.

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).
