Introduction

　A lime kiln is a 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

YUHONG lime rotary kiln can work with vertical preheater and vertical cooler to achieve the advantages like high use ratio of raw materials, complete calcination, even quality, good quality lime, high capacity output, environmental and energy saving, simple operation and longer working life. This kiln is very suitable for limestone calcination for industries like metallurgy, chemical, construction materials and etc.

A lime kiln is used to produce quicklime through the calcination of limestone (calcium carbonate). This reaction takes place at 900 °C but a temperature around 1000 °C is usually used to make the reaction precede quickly.2 Quicklime was used to make plaster and mortar for building construction. By adding sand to the mix, bonding between the sand and the lime results in a hardened product (either mortar or cement) that keeps its shape over time. Another lime-based product was whitewash, which was quicklime that had been saturated with water, and then mixed with glue. After processing, products derived from limestone have the unique ability to return to their original chemical form. The lime cycle consists of first burning of limestone to form quicklime. Hydrated lime can then be produced by adding water to the quicklime. At this point, carbon dioxide in the atmosphere or from industrial processes reacts with hydrated lime to convert it back to limestone. This cycle is called the lime cycle. Limestone is a naturally occurring and abundant sedimentary rock consisting of high levels of calcium and/or magnesium carbonate, and/or dolomite (calcium and magnesium carbonate), along with small amounts of other minerals.
