Facing Rotary Kiln Challenges? 4 Solutions to Help You!
Solution II: Easily prevent kiln ring formation Ensuring normal rotary kiln flame is one challenge; another is material looping. This occurs when furnace charge adheres in a ring shape to the inner wall of the high-temperature zone. Minor adhesion is termed kiln skin, while thicker adhesion affecting furnace operation is called ring formation.
