What is a Raw Mill in a Cement Plant? A raw mill is an equipment used to grind raw materials into "raw mix" during the manufacture of cement. Raw mix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement. How Does a Raw Mill Work in a Cement Plant? A raw mill comprises several components …

Where, G is another constant. The majority of the kiln feed is limestone, which does not have to be finer than 125 µm. If an argillaceous limestone (cement rock) is used, it may be possible to obtain good burnability at particle sizes considerably coarser than this (since the effective calcite grain size is smaller than the particle size).
