The enthalpy change at 25°C is +43.989 kJ/mol: at 100°C it is +40.865 kJ/mol. The typical clinker mentioned above has 1.5429 kg of notional dry rawmix per kg clinker made, and if this takes the form of a slurry with 38% free moisture, then 0.9456 kg (52.49 mol) of water must be evaporated, with a heat input of 2145 kJ/kg clinker.

After the clinker enters the cooling machine from the kiln, a layer of a certain thickness is laid on the slab, and the blasted cold air is quenched in the direction perpendicular to each other through the layer of the moving material on the boring machine to allow the clinker to be quenched. The clinker is quenched from 1300-1400 ° C to below 100 ° C in a few minutes. The traditional ...
