Rawmill - Wikipedia
A raw mill 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 raw milling stage of the process effectively defines the chemistry of the finished cement, and has a large effect upon the efficiency of the whole manufacturing process.
