The capacity of the vertical raw mill is often the limiting factor for clinker output – when a plant upgrades the kiln system, the raw mill frequently becomes a bottleneck. Rather than investing in an entirely new vertical mill to keep pace, there is a very limited set of possibilities in upgrading existing mill capacity in smaller steps.
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 ...
