Alite formation and other reactions at 1300 °C - 1450 °C in the burning zone. In the burning zone, above about 1300 °C, reactions take place quickly. The clinker is in the burning zone for perhaps 10-20 minutes but in this time a lot happens: The proportion of …
As the meal passes through the burning zone, it reaches clinkering temperatures of about 1400 C - 1500 C. Nodules form as the burning zone is 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.
