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
