The temperature in the kiln ranges from 1200°C at the terminal end to 1000°C at the upper end. Not all of the limestone is converted to lime. A small amount known as 'loss on ignition' (LOI) remains. This is about 0.5–1%. Every hour, a sample of lime chip exiting the kiln is taken and sent to the on-site lab for analysis. Acknowledgement:
