The potential to install new modern PFR lime shaft kilns for product egory #1 at low or stagnating market growth is still substantial because today the number of modern PFR lime shaft kilns is less than 800. This means that there are still high quantities of lime being produced with outdated kiln models.
The next common type of kiln is the vertical shaft kiln. This kiln can be described as an upright heavy steel cylinder lined with refractory material. The limestone is charged at the top and is calcined as it descends slowly to discharge at the bottom of the kiln. A primary advantage of vertical kilns over rotary kilns is the higher fuel
The calcination principle of composite firing shaft kiln is: mix the solid fuel (coke or anthracite) with qualified stone evenly, use rotary discharging device equipped on kiln roof to discharge the mixture into the kiln, then under its own gravity the mixture proceeds through preheating area, calcining area, cooling area, and finally calcined into qualified finished lime product.
