captive lime production) and in 2006, there were a total of 597 kilns producing commercial lime, of which 551 (or about 90 %) were shaft kilns. Typical kiln size lies between 50 and 500 tonnes per day for shaft kiln types. Lime production generally uses between 1.4 and 2.2 tonnes of limestone per tonne of saleable quicklime.
A lime kiln is used for the calcination of limestone (calcium carbonate) to produce quicklime also called burnt lime. Usually, the heat is around 900 Degree Celsius, but a temperature around 1000 Degree Celsius is used to make the calcination process more quickly. Excessive temperature is discouraged because it produces "dead-burned" lime ...
