✦ Synopsis

ABSTP~ACT

The relationship between specific power consumption (Id.~/t) and Blaine fineness attained during grinding of the Portland clinker is represented by an exponential function. This function varies by stages. For each stage the following equation may be written: In k~.~/t = a + bS, where S is the Blaine fineness and a and b are constants assigning different values at each stage. The values of these constants for the first stage,up to about 250 m2/kg Blaine, are not significantly affected by the chemical composition of the clinker, while at the second stage, about 250 -500 m2/kg Blaine, the values of the constants are affected by C3A , C4AI~ , K20 and MgO contents.
