Rawmill - Wikipedia

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.
