Abstract

Improved procedure for the manufacture of white cements consisting of preheating the appropriate crudes for the manufacture of white cements until the decarbonization is approximately 850º, after taking them to an oven at the temperature of 1450º and then cooling them in two different phases, a first, until the vicinity of 700º by means of an air flow used as oxidizing air by the burner of the firing oven, and a second, from 700º to room temperature, in the course of which, the colored clinker, in the course of The said first phase is either cooled by normal means in order to produce gray cement clinker or reheated between 800 and 1200º and subsequently air-cooled in order to produce white cement clinker.
