    Rawmill Wikipedia

    27/02/2007· 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

    Raw Material Preparation Cement Plants and Kilns in

    From the early 1900s, both for cement grinding and for grinding hard raw materials, whether by wet or dry process, the standard arrangement was a ball mill for preliminary grinding (to below 0.75 mm), followed by a tube mill for fine grinding. Typically the ball mill was placed on an upper floor so that material could move by gravity. An example was the original rawmill system at

    Raw meal silo level measurement and point level

    The cement kiln

    The raw materials, limestone and shale for example, are ground finely and blended to produce the raw meal. The raw meal is fed in at the top of the preheater tower and passes through the series of cyclones in the tower. Hot gas from the kiln and, often, hot air from the clinker cooler are blown through the cyclones. Heat is transferred efficiently from the hot gases to the raw meal.
