Sub-micron grinding experiments were carried out by using different amounts offiner grinding media (25%, 50% and 75%) and different size ratio of finer-coarser media (0.2 and 0.5).Besides, the surface areas (Sbw, m2/kg) of grinding media on grinding performance were investigated. Ifthe best experimental results are compared (M1 and M4), it is found that the Sbw of the bimodal media(M4) is 75% larger compared to that of monosized media (M1). The experimental results were analyzedbased on product size (d50, d80), cumulative undersize curves and specific surface area (SW, m2/g). Thefindings showed that only the finer grinding media was not very effective at 600 rpm.eninfo:eu-repo/semantics/openAccessMühendislikKimyaTHE EFFECT OF GRINDING MEDIA PERFORMANCE ON WET MILLING OF CALCITEArticle7237938610.15317/Scitech.2019.206345169
