The cooling zone in the kiln is actually quite short but it is in this zone that nodulisation of the melt occurs. The red hot clinker is then discharged into the cooler, where it is quenched cooled to around 100 degrees centigrade. The heat dissipated by the clinker is used as secondary air for the combustion in …
