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.
These admixtures increase the productivity of the grinding aid at the same time. Performance Enhancer Clinker is often replaced with supplementary cementitious materials (SCM) such as granulated blast furnace slag, natural pozzolanes and fly ash in order to reduce CO 2 emissions and material cost.
