Rawmill - Wikipedia

A rawmill 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 rawmilling stage of the process effectively defines the chemistry (and therefore physical properties) of the finished cement, and has a large effect upon the ...

Clinker quality depends on raw material composition.

Portland cement is the most common type of cement in the world. It is used primarily to make concrete, mortar, and grout. Portland cement manufacturing begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln.
