  • CLINKER COOLING TECHNOLOGY Mechanical

    Rapid cooling of clinker is done because of the following reasons. 1. In slow cooling, MgO crystals are formed which, during hydration of cement, form Mg (OH) 2. The hydroxide thus formed occupies 39 times the volume of MgO and hence causing expansion cracks.

    Reactions in the cement kiln clinkering

    Fast cooling of clinker is advantageous it makes for more hydraulically-reactive silicates and lots of small, intergrown, aluminate and ferrite crystals. Slow cooling gives less hydraulically-reactive silicates and produces coarse crystals of aluminate and ferrite. Over-large aluminate crystals can lead to erratic cement setting characteristics.

    Cement Kilns: Clinker Minerals

    When magnesia content is high, the most usual means of mitigating the problem is to ensure the clinker gets very rapid cooling, so that the periclase solidifies as very small and therefore more rapidly soluble crystals. The formation of large periclase crystals during slow cooling can lead to bad expansion of mature concrete.
