1. The relationship between the grinding energy consumption
and the specific surface area attained can be
represented by an exponential function. The constants
of the exponential function depend on the chemical
composition of the clinkers.
2. Energy requirement for a specified fineness of the
ground clinker decreases with increasing Al2O3 content.
The reduction is more pronounced for alumina
contents above a certain value, which was found to be
about 6% in this investigation.
3. The relationship between grinding energy requirement
and free lime content of the clinker is logarithmic, where
energy increases with increasing free lime content.
