Introduction. In various dry fine grinding applications, socalled grinding aids (GAs) are added to the feed material or directly into the mill either to a) increase the production capacity, b) reduce the specific energy demand, which is required to obtain a certain product quality, or c) achieve finer material or a better performance of the later product.

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.
