A suspension-calcined lime kiln is a highly efficient lime-burning facility. Its operating principle is to suspend limestone powder in a high-temperature airflow, producing lime through a pyrolysis reaction. This equipment boasts high thermal efficiency, high production efficiency, and high-quality lime, making it widely used in modern industry. It offers the following advantages:

1) The raw material entering the kiln is in powder form, resolving the problem of traditional lime kilns being unable to use particles smaller than 20 mm.

2) The limestone mine raw material has a high overall yield rate, allowing limestone with a calcium oxide content of over 46% to be homogenized with high-calcium stone for reuse.

3) Utilizing suspension combustion technology, thermal efficiency can reach over 90%.
