• Raw Material Preparation

    It is interesting to note that when James Parker commenced making his “Roman” Cement, he set up at Northfleet, not for reasons of raw materials or market, but because a water mill was available. In the cement industry context, this technology was difficult to apply because the grinding stones consisted usually of fine-grained sandstones not

    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

    Raw materials Understanding Cement

    Technically, a cement producer can have almost complete control over clinker composition by blending raw materials of different compositions to produce the desired result. In practice, however, clinker composition is largely determined by the compositions of the locally-available raw materials which make up the bulk of the raw meal.
