    Rotary kilns run at a higher temperature than the ambient air, thus any ambient air that leaks into the rotary kiln will cause the temperature inside of the kiln to drop. Quality leaf seals then function to minimize air leakage into the kiln, which ultimately allows the chemical reaction to take place, reduces fuel consumption, and can
