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 ...

When it comes to mill control, operators rarely concentrate on pushing mill production when the kiln is regarded as the key. Expert systems on mills should be universal and well tuned. Grinding aids can give benefits of 5-15 per cent in production but need to be continuously evaluated for cost effectiveness.
The MPS mill also grinds, dries, calcines, and classifies gypsum without any problem, all in a single machine, for any fineness requested and considering individual requirements. The MPS vertical roller mill - built to last, reliable and energy-efficient - is the optimum solution when it comes to performing several process steps in one unit.
Roller mill is a form of compression mill that uses a single, double, or triple cylindrical heavy wheel mounted horizontally and rotated about their long axis either in opposing pairs or against flat plates, to crush or grind various materials.
