equipment for raw meal storage and kiln feeding. IKN's responsibility included detailed engineering of process ducts, material and dust transport, steel structures, and the integration of the raw mill into the new plant. The raw mill circuit followed the two fan system and was delivered under a separate contract between Italcementi and Gebr.
These raw materials are crushed and fed to a raw mill. Raw mill is also known as secondary crushers or hammer mills. Raw mill output is known as "raw feed" or "kiln feed". This raw feed must be pre-heated and completely dried up before passing it through the kiln [2].Pre heating is performed to remove the
