Raw mills for all requirements | Gebr. PfeifferDepending on its deposit and composition, the cement raw material may contain a more or less big portion of water. Especially with high feed moistures, drying is of particular importance because the existing surface moisture has to be evaporated almost down to zero in the raw mill. The thermal energy required for this.cement ball mill raw mill,cement ball mill raw mill,Rawmill - WikipediaA rawmill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement mill. The rawmilling stage of the process effectively defines the chemistry (and therefore physical.
