• PERSONALIZZATA E ENGINEERING AND

    At a specific load of 45.3 t/dm and 1.78 Nm/kg cooling air, a cold clinker temperature of 65˚C above ambient temperature is achieved. The intensive cooling of the clinker is realised by a long retention time inside the cooler. At maximum stroke numbers of 4 min-1 the ETA cooler can be operated with clinker bed heights of up to 1300 mm.

    Summary of production process. The material formed in the kiln is described as 'clinker' and is typically composed of rounded nodules between 1mm and 25mm across. After cooling, the clinker may be stored temporarily in a clinker store, or it may pass directly to the cement mill. The cement mill grinds the clinker to a fine powder.

    The rapid cooling of the clinker as it passes under the flame in the kiln and falls into the cooler results in non-equilibrium cooling with the liquid flux in the clinker being frozen into a glass. This non-equilibrium cooling means that the clinker mineral composition is frozen at its high-temperature equilibrium with significant deviation from the Bogue composition.
