The lime chip exiting the rotary kiln falls on to a system of conveyors. Air is blown over the chip to cool it down. The hot air that results from this is blown back into the kiln.

The cooled chip is crushed to a powder, known commercially as ‘burnt lime’, and this is either bagged or loaded into shipping containers. Transport to customers is by either road or rail.
