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 that work together to produce the desired raw mix.
