A mediumsized dry process roller mill. 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 raw milling stage of the process effectively defines the chemistry (and therefore physical properties) of the finished ...

To change pattern of cement — initially separator fan shall be adjusted. In principle, the higher separator speed yields finer cement and the higher air flow coarser cement, the higher separator speed should shift the Tromp curve to the left (lower x50), whereas the higher air flow rate to the right (higher x50).
