  • Raw Material Preparation

    This meant that, for the first time, there was virtually no limit on the fineness that could be achieved From the early 1900s, both for cement grinding and for grinding hard raw materials, whether by wet or dry process, the standard arrangement was a ball mill for preliminary grinding (to below 075 mm), followed by a tube mill for fineA 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 millThe raw milling stage of the process effectively defines the chemistry (and therefore physical properties) of the finished cement, and has a large effect upon theRawmill Wikipedia
