The function of the kiln system is to convert the raw meal into clinker in the most efficient way and to produce clinker with an optimal mineralogy for acceptable cement performance. Typical chemical analysis of raw meal, clinker, and select processing parameters are given in Table 3.1.2. Table 3.1.2.

In present – day cement manufacture, with due regard to the possibilities of the reduction machinery employed, crushing is taken to mean reducing the particle size between about 80 and 20 mm. This crushed product is further reduced by grinding to fineness below about 0.2 mm size, in which condition it is called raw meal and is ready for feeding to the kiln.
