In this study, the effect of grinding aid on dry calcite grinding using vertically and horizontally orientable stirred ball mill was investigated. The results obtained from the vertical and horizontal orientation of the mill were evaluated based upon the particle size (d50 and d90). For vertical orientation, experimental results indicated that the d50 and d90 sizes can be improved by 40% …
