Particularly the increasing use of alternative fuels leads to extremely high thermochemical and thermomechanical stresses in the refractory lining. Based on the material flow, a rotary kiln is usually divided into the following zones: 1. Kiln inlet cone 2. Preheating zone 3. Calcining zone 4. Upper transition zone 5. Clinkering zone 6.
