Lime Kiln | Lime Rotary Kiln Plant - Lime Kiln ...

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 which is unreactive.
