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 ...

After inspecting the brand of cement grinding mill, the following is to choose the cement mill that suits you. Under normal circumstances, you need to have a general understanding of your own raw materials, processing fineness, capacity, etc., and use these actual production requirements as reference data to select and find the mill equipment needed for your own cement grinding plant.
In this process, the chemical bonds of the raw materials are broken down and then they are recombined into new compounds. The result is called clinker, which are rounded nodules between 1mm and 25mm across. The clinker is ground to a fine powder in a cement mill and mixed with gypsum to create cement.
