cement rotary kiln burning zone

Theburning zoneis that area in thekilnwhereclinker coatingexists on therefractorysurface. IN   the   drying   and  preheating    zone    all  the   free  water   in   the  feed    is  removed and the temperature of the feed is raised  to approximately ·805  C (1481 F) at which temperature calcination begins.

As the meal passes through the burning zone, it reaches clinkering temperatures of about1400 C - 1500 C. Nodules form as theburning zoneis approached. When the clinker has passed the burning zone, it starts to cool, slowly at first, then much more quickly as it passes over the 'nose ring' at the end of the kiln and drops out into the cooler.
