Coating Formation In Cement Kiln

The kiln coating formation mechanism of MgO–FeAl2O4

2016-1-1  The good kiln coating formation mechanism is discussed based on the phase and microstructure of the different part of the brick after usage. It is found that the liquid phase of the cement clinker diffuses into the periclase crystal boundaries of MgO–FeAl 2 O 4 brick and causes the content gradient of Fe and Al ions between the periclase ...

why coating formed in kiln

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 ...
