• important operation tips for cement vertical mill

    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. When the vertical mill inlet and outlet dampers are balanced, the system's wind will be balanced and will not affect the pressure at the kiln end.

    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 the chemistry (and therefore physical properties) of the finished cement, and has a large effect upon the efficiency of the whole manufacturing process.
