One of the special features of this Shaft Kilns is the process operation that works upon the principle of counterflow. Based upon the moderate burning conditions, a lime product with higher reactivity is produced. It also allows the transportation of lumpy raw material into a feeding system that is airlocked at the top of the kiln. The mentioned product is capable of using any kind of fossil fuel to be supplied through the combustion chamber that is attached externally.
