Abstract The effect of clinker grinding aids (GAs) on mill performance and cement properties is currently quantified in real-scale grinding plants. In fact, laboratory-grinding mills operated for given time interval do not consider the effect of circulating load, thereby leading to increased specific energy consumption (Ec) with excessively wide cement particle size distribution (PSD) curves.

Portland cement clinker: the Bogue calculation The Bogue calculation is used to calculate the approximate proportions of the four main minerals in Portland cement clinker. The standard Bogue calculation refers to cement clinker, rather than cement, but it can be adjusted for use with cement. Although the result is only approximate, the calculation is an extremely useful and widely-used ...

This research focused the role to study the effects and ways to control the chemical composition of clinker for better cement production. Cement is a substance produced by grinding a mixture of a clay and limestone and heating to a temperature of 1450°C, in which the chemical transformation occurs inside the kiln to form new compound called clinker.

The clinker is ground in a vertical roller mill. The cement is ground so fine that it will easily pass through a sieve that is fine enough to hold water. Up to 5 percent gypsum or natural anhydrite is added to the clinker during grinding to control the cement setting time. Up to 5% limestone may also be ground with the clinker and gypsum.
