1200TPD 2.5×40M Lime Rotary Kiln Active Lime Calcining Equipment

Lime Rotary Kiln (Active Lime Calcining Equipment) Description:

Rotary kiln used for the calcination of limestone (calcium carbonate) to produce the form of lime called quicklime (calcium oxide). The chemical equation for this reaction is

CaCO3 + heat → CaO + CO2

This reaction takes place at 900 °C-1350°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.

Advantages of Lime Rotary Kiln (Active Lime Calcining Equipment):
1. High productivity makes it possible for our lime rotary kiln to be used in large active lime production line.
2. Open-type calcining rotary kiln has a simple structure, and can discharge sulfurous gases timely, which makes it quite suitable for steelmaking.
3. It is capable of calcining 10 to 50mm fine limestone directly.
4. Vertical preheater has been equipped at the end of the kiln to make full use of high-temperature gases generated during calcining. It can preheat limestone to the decomposition conditions. In this way, it helps not only to increase the output, but also to decrease the heat consumption.
