Rawmill - Wikipedia

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 ...

Cement Kilns: Suspension preheater kilns

After separation by the cyclone, the raw meal passes out through a one-way valve which prevents hot gas from coming up the feed pipe. The more stages are used, the more efficient the preheater is. But each stage increases the pressure drop across which the kiln fan must work, and with more than six stages, the fan power requirement is prohibitive.
