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 …

are hydraulically lifted from the grinding track before the mill motor is started. The mill can then not only be started empty but also par- tially filled with a low starting torque. Metallic contact of grinding parts on an empty or loaded mill is pre- vented by automatic lifting of rollers via a grinding bed depth control.
The Cement Manufacturing Process - Advancing Mining
The clinker is ground to a fine powder in a cement mill and mixed with gypsum to create cement. The powdered cement is then mixed with water and aggregates to form concrete that is used in construction. Clinker quality depends on raw material composition, which has to be closely monitored to ensure the quality of the cement. Excess free lime ...
