Portland cement clinker overview. Portland cement clinker is a dark grey nodular material made by heating ground limestone and clay at a temperature of about 1400 °C 1500 °C. The nodules are ground up to a fine powder to produce cement, with a small amount of gypsum added to control the setting properties. This page gives a thumbnail sketch.

Introduction. The production of fine particles in the lower micron range by dry grinding processes demands large amounts of energy. For instance, the cement industry alone consumes approximately 1215% of the world's total industrial energy, whereby the fine finish grinding of the cementitious products accounts for about 30% of the overall energy consumption (Madlool, 2011).

The effect of clinker grinding aids (GAs) on mill performance and cement properties is currently quantified in realscale grinding plants. In fact, laboratorygrinding 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.

Sohoni et al. [14] investigated the influences of seven grinding aids on the batch grinding of limestone, Portland cement clinker and quartz. It was observed that the grinding aids had only a negligible impact on grinding of quartz although they had a considerably beneficial effect on the grinding of clinker and limestone.
