Ix rises Typical clinker nodulesAlite is the characteristic constituent of Portland cement Typically a peak temperature of 1400 1450 C is reuired to complete the reaction The partial melting causes the material to aggregate into lumps or nodules typically of diameter 1 10 mm This is called clinker The hot clinker next falls into a cooler which recovers most of its heat and cools the clinker to around 100 C at which temperature it can be conveniently conveyed to storage The cement kiln system is designed to accomplish these processes Portland cement clinker was first made in 1842 in a modified form of the traditional static lime kiln The bas.
