Sep 01, chapman et al. () compared the effects of using different circuits hpgr (dry) -rod mill (wet) and cone crusher (dry) -rod mill (wet) on the flotation of base metal sulfides. they indicated that apart from the grinding environment, hpgr could produce finer particles than a cone crusher. this difference was higher in the fully dry.
Simply put, if you want to have the option of a super fine flour, then a burr grinding mill is a good choice. an impact mill, although will get you fine flour, won’t produce flour that is super fine. for bread making, a finer texture is useful for whole grains, as this will help give the bread a lighter.
