Abstract
A method of and an apparatus for cooling white cement clinker from a rotary kiln wherein the clinker is classified into at least two and preferably more particle-size fractions which are quenched with water with residence times staggered so as to increase as the particle size range increases. The cooling is effected to a temperature of below 1200.degree. C. but without excessively cooling the clinker so that all fractions retain sufficient sensible heat to drive off water picked up during the quenching process and resulting in completely dry clinker.
