These four small kilns are served by a common stone feed system; product from all four kilns discharges to a common lime handling and storage system. An unusual feature of the four small kilns is that they also share a common bag house and a single 1000 hp fan. This arrangement complicates the draft control of the individual kilns.

Dec 11, 2018· White cement kiln feed is difficult to combine due to the lack of iron oxide to form flux in the kiln. The higher the 90 micron residue the harder it becomes to combine the clinker. Therefore it is common practice to grind the kiln feed to a low residue of less than 5% on a 90 micron sieve. Finer grinding might solve your problem.
