This paper mainly introduces the raw mill in cement plant. In order to achieve the desired setting qualities in the finished product, a quantity (28%, but typically 5%) of calcium sulfate (usually gypsum or anhydrite) is added to the clinker and the mixture is finely ground to form the finished cement powder. This is achieved in a cement raw mill.

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 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 ...
Raw meal is fed into one end of the kiln, either directly or via a preheater system, and pulverized coal is burnt at the other end. The raw meal slowly cascades down the inclined kiln towards the heat and reaches a temperature of about 1 450 °C in the burning zone where a process called clinkering occurs.
