  • Rawmill - Wikipedia, the free encyclopedia

    A 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 For this reason, the early cement industry used the "wet process", in which
