Combination of Conventional Ball Mill and Stirred Mill to Obtain Ultra-Fine TalcUçurum, MetinGüleç, ÖmerToraman, Oner YusufMaden İşletme ve Cevher HazırlamaMalzeme Bilimleri, Özellik ve TestIn this study, it was investigated that talc ore could ground to very fine sizes using a combination of conventional ball mill and vertical stirred mill. Firstly, the conventional ball mill parameters such as mill speed (% of critical speed), material filling ratio (Jb), ball filling ratio (fc), ball size distribution (10-20-30-40 mm, %), grinding aid ratio (% of powder) and grinding time (min.) were optimized using classic experimental design. As a result of the optimization, fine talc product was obtained with d90=93.52 µm particle size. In the second stage, the ball mill product was re-milled using a stirred mill. As a result of study, a final ultra-fine talc powder was obtained after 60 minutes grinding time with d50=1.85 µm particle size and 14058 cm2/g total surface area. It has been seen that the conventional ball mill+stirred mill combination effective a process to obtain talc powder that suitable for industrial use.2023Articlehttps://rdlopen.rawdatalibrary.net/r/bayburt/15651https://doi.org/10.21605/cukurovaumfd.13777252757-9255enÇukurova Üniversitesi Mühendislik Fakültesi dergisiinfo:eu-repo/semantics/openAccessinfo:eu-repo/semantics/articlehttps://bayburt-rdlopen.rawdatalibrary.net/tr/items/bayburt/15651
