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 ...

Use of Slag as Raw Material | Industrial Efficiency ...

Blast furnace slag and other lower quality slag streams from iron and steel and non-ferrous metal manufacturing, containing 40 to 45% CaO, can be used as a raw material for clinker making, after being ground together with the other raw materials. Slag use of up to 250 kg/t-clinker is reported from Japanese plants (APP, 2010, p. 119).

How Cement Is Made

Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects. Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process.
