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 SICEMENT Automation Cement Siemens Global,The cost of coal and fuel is always on the rise and most plants us a big variety of fuels and waste materials for the kiln which makes it even harder to control the burning process. Continuous gas analyzers at critical locations can contribute massively to the optimization of the cement process and significantly reduce the production costs.
