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.

The consumption of the energy in the cement plant is mainly due to raw mill, cooler, preheater and rotary kiln . The total energy loss of the plant is generally accounted for about 3539% of the total energy input . This energy loss is due to the loss from the exhaust gas, cooler and the radiation heat transfer from the kiln cell.
