  • WO2011051962A2 A process for manufacturing white cement

    May 18, 2011 In cases where in the clinker Fe203 content is above 0.2% (which is almost always the case), the unique processes of "quenching" is also employed. In white clinker production, where the iron content is low, this is not an issue. Subsequently, to prevent the reoxidation of the iron, "quenching" is performed.
