Discription of lime kiln
A lime kiln is a kiln used to produce quicklime by the calcination of limestone (calcium carbonate). The chemical equation for this reaction is:
CaCO3 + heat → CaO + CO2
This reaction takes place at 900°C (at which temperature the partial pressure of CO2 is 1 atmosphere), but a temperature around 1000°C (at which temperature the partial pressure of CO2 is 3.8 atmospheres) is usually used to make the reaction proceed quickly. Excessive temperature is avoided because it produces unreactive, "dead-burned" lime.
Rotary kilns started to be used for lime manufacture at the start of the 20th century and now account for a large proportion of new installations. The early use of simple rotary kilns had the advantages that a much wider range of limestone size could be used, from fines upwards, and undesirable elements such as sulfur can be removed.
Our Lime Kiln features in,convenient and reliable control of the production process, less wearing parts, high rates of operation, The Lime kiln also has strong structure, stable operation, low energy consumption, high-quality products,large capability from the kiln and so on advantages, we can also offer advanced efficient shaft preheater, five grade cyclone preheater.
