2.3. Effect of SM of clinkers on grinding energy
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.
