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 eff

Raw milling and blending - INFINITY FOR CEMENT EQUIPMENT
Continuous blending involves simultaneous feeding of the silo, overflow to a second silo and final discharge to kiln feed. Modern equipment generally uses continuous CF silos, each having capacity of more than 24-hours’ kiln feed and yielding a blending ratio (or ‘blending factor’) of 4-8, or around 2-3 for older silos.
