slurry. These nodules should not be too strong because they must be cracked by thermal shock or abrasion before being fed to the kiln system via top stage of the pre-heater. A two-stage pre-heater kiln operated with semi-wet nodules was e.g. the Liesberg plant. There, the nodules were cracked in a vertical dryer before being fed to the preheater.

OPERATIONS STRATEGIES FOR VERTICAL SHAFT LIME KILNS

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 ...

Lime kiln - Wikipedia

Shaft kilns. The theoretical heat (the standard enthalpy) of reaction required to make high-calcium lime is around 3.15 MJ per kg of lime, so the batch kilns were only around 20% efficient.The key to development in efficiency was the invention of continuous kilns, avoiding the wasteful heat-up and cool-down cycles of the batch kilns.
