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 ...

Mills belong to a class of equipments that accomplish comminution of materials in the fine range. There are two types of mills which are mostly used in cement plants for grinding raw mix viz. Ball mills and VRM. Ball mills Ball mills are essentially fine grinding units capable of grinding material to a fineness say 84% passing 90 microns.

However, if the grinding of raw mix or the cement clinker is carried beyond 4 000 cm/g, the use of grinding aids can be of definite advantage. Moreover, it would be worthwhile to undertake studies on the effect of grinding aids on other properties (e.g., water to cement ratio, strength development characteristics, etc.) of the ground cement.
