The raw mill is a closed circuit air swept ball mill. The raw meal product is transported into blending silo by air slide and bucket elevator. The hot gas out of preheater is used as the heat source for drying in raw mill. There is also a standby oil furnace for supplying the hot gas when the kiln stops or the hot gas from preheater is not ...

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 ...
