The relationship between the SM of the clinkers used in
this investigation and the grinding energy consumption calculated
by using the constants A and B given in Table 4 is
shown in Fig. 4 for three different specific surface areas
(2800, 3400, and 4000 cm2/g).
The relationship between grinding energy requirement and SM can be described
by a second-order polynomial (solid line).
The extremum points of the polynomial where the energy requirement is maximum
decrease linearly with increasing fineness (2.71, 2.48,and 2.27 for 2800, 3400, and 4000 cm2/g, respectively).
However, for specific surface areas around 3000cm2/g, the curve can be approximated as a line where the energy requirement increases with increasing SM.
