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.
