    Improved Lime Mud Kiln Control System. A Lime Mud Kiln consists of three sequential operating zones drying, heating, and calcining. To achieve proper calcination, lime is subjected to the calcining temperature for a certain length of the kiln. Since calcining is the final zone, any deviation from its required length causes variations in
