mill function in cement industry. Rawmill - Wikipedia. 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 theApplication of ICT in Multivariable System Identificationand simulated model output of identified ARX model and NARX model for the cement mill level (z) with 5040 samples of real cement mill data.

When the raw material is running in the vertical mill, the drying heat source of the material comes from the hot gas at the kiln tail. Therefore, when the vertical mill is operated, the control of the inlet and outlet dampers should be balanced by the kiln mill.
