What does a Raw Mill do in Cement Plant?
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.
Vertical Roller Mill in Cement Manufacturing Plant
A cement vertical roller mill (VRM) is a type of grinding equipment commonly used in cement plants for raw material grinding and cement grinding. It is an energy-efficient alternative to traditional ball mills, as it utilizes rollers to grind and crush the materials between a rotating grinding table and a set of rollers mounted on a vertical axis.
