Calcined Lime

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.

In addition, Azar Sepid Sepahan Company has been recognized as one of the outstanding companies producing high quality lime and Calcined Lime through having kilns with 3m diameter and 55m length with 26m preheater.
