    From the limestone quarry to the delivery of the end product, follow every step in the cement manufacturing process. The hot gases coming from a preheater (preheater / kiln system) enter the mill and are used in raw mills for drying. Then the drying materials enter the grinding chamber of raw mills for fine grinding.

  • Rawmill Wikipedia

    A rawmill 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 rawmilling stage of the process effectively defines the chemistry (and therefore physical

Here, hot gases from the kiln, and probably the cooled clinker at the far end of the kiln, are used to From both a process and chemical viewpoint, it is beneficial to minimise clinker temperature as it enters the cement mill.

    Cement production typically requires the grinding of three separate types of material during the process: the raw ma terials and coal before the kiln, and the final cement product once firing is complete and the clinker cooled. Looking back on a century or more, ball mill systems were used for all three grinding stages, but the
