How does a Lime Kiln Work
To produce quicklime in lime kilns, there are mainly three processes. The first stage is preheating. The second stage is calcining. And the third stage is cooling. In the preheating stage. The feed limestone is preheated by the exhaust hot air from the lime kiln, so that partially of the limestone will be calcined.
