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.
