Jun 11, 2008 Re Coating formation in Kiln Inlet. Hi. Coating at kiln inlet ia mainly due to the volatiles like Chlorides, alkalies Na2O and K2O and SO3. To minimise the coating formation, the alkali sulfate ratio should be around 1.1 so that these volatiles will come out as alkali sulfate along with the clinker so that the recirculation inside the kiln circuit will be less.
Cement kiln refractories. Refractories play a critical, if unseen, role in both the rotary kiln lining, and the lining of the high volume static equipment areas that comprise a modern pre-calciner kiln system. The durability of the rotary kiln brick lining generally determines the duration of a kiln operating campaign.

Rotary kilns have become very established in fields such as cement, lime, and minerals. Because these thermal processing tools have been used almost exclusively in these industries, they have been designed to meet the needs of these particular materials. However, there are countless untapped applications for the use of a rotary kiln.
