Wet grinding rod mills are normally used in the mineral processing industry. dry grinding is used in some areas; however, it is confronted with problems and should be avoided except where absolutely necessary. rod mills operate at lower speed than ball mills since the rods are rolled and not.
Yet, no wet-milling of grain sorghum is being done principally because grain sorghum's germ is small and its endosperm contains cross-linked proteins. the fact that wet-grinding of grain sorghum with no steeping of the grain gave 78 percent recovery of starch forms the basis of a low-cost process to produce starch and feed from grain.
