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 (and therefore physical properties) of the finished cement, and has a large effect upon the effOptimizing Raw Mills Performance ; the Materials WAY,622· A review of recent raw mill designs indicates that increasing the maximum design raw material moisture from 4% to 17% would result in a doubling of the installed fan capacity.
