2.2. Effect of free lime content of clinkers on grinding energy
The relationship between the free lime contents 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. 3
for three different specific surface areas (2800, 3400, and 4000 cm2/g).
The overall relationship (solid line) indicates that grinding energy requirement
increases logarithmically with increasing free CaO.
