Calcined Lime

Calcined Lime is being made through burning Limestone under 1000-1200°C. Rotary, vertical, or rotary-vertical kilns are applied for the industrial lime burning. Limestone is being kept in the kilns at least for 2:30-3 hours. Therefore, the more it takes burning, the quality of produced lime (Calcined Lime ) will be improved.


The main mineral constituent in lime is called “Calcite” with the chemical formula CaCo3. Carbonate calcium is the equivalent. Limestone or carbonate calcium is rarely found in the form of pure lime in the nature. This stone is mostly seen in the form of Clay-line, sand-lime, and dolomite.
