    Lime kiln is a rotary combustion kiln where heat transfers from combustion gas to lime particles. Lime kilns are typically 2-4 m in diameter and 50-120 m in length with typical rotation speed of 0.5-1.5 rpm. Lime mud is feed to the kiln from cold end and the kiln slopes slightly, about 1-4 per cent toward the firing end. Lime mud moves slowly
