  • Grinding aids for dry fine grinding processes Part I

    2020-9-20 · For instance, Dombrowe et al. investigated the impact of grinding aids on the grinding limit of clinker grinding in laboratory ball milling. They showed that agglomeration and product adhesion are significantly reduced by grinding aids especially in the range of very fine particles in the lower micron range, leading to a shifting of the grinding limit towards higher product fineness.
