Grinding experimentswere carried out by using different proportions of finer grinding media (20 wt.%, 40 wt.% and 80 wt.%)and different size ratio of finer-coarser media (0.5 and 0.67). Besides, the surface areas (S bw, m 2 /kg) ofgrinding media on grinding performance were investigated. If the best two experimental results arecompared, it is found that the S bw of the bimodal and monosized media are very close together. Theexperimental results were evaluated based on the product particle size (d 50 , d 90 ), and the geometricstandard deviation of barite particles (d 84 /d 16 ). The findings showed that the finer grinding media alonewas not very effective.eninfo:eu-repo/semantics/openAccessMikroskopiMalzeme BilimleriÖzellik ve TestArticle342113120322473
