The effects of grinding chemicals on grinding results have been studied in a laboratory scale ball mill by Sverak et al. [14]. In this study eleven types of chemicals were tested while grinding Portland cement clinker. The evaluations focussed on the variation of grinding time with 08 μm or 030 μm yields. The paper concluded that ...
