1. Introduction. In various dry fine grinding applications, so-called 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.applications. The two additives have only little effect on water absorption and fi nal hardness due to their fi lm-forming properties. WorléeDisperse VP 8460W is amine-free. WorléeDisperse VP 8470W is a highly concentrated dispersing agent. It was specially developed for grinding of organic pigments
