Cement rotary kiln is the most vital part of a cement factory whose outcome is cement clinker. A rotary kiln is a cylinder with a length of around 70 meters and a diameter of around 5 meters in a factory with a capacity of producing about 2000 tons of clinker in a day. The kiln is rotated by a powerful electrical motor.

When starting up a cold kiln, it is important to allow time for the tire rings to expand in pace with the kiln shell's expansion. If heat-up is too rapid, the colder tire rings can cause shell deformation, thus crushing refractories. When the tire rings later expand to full operating dimensions, this can cause 'rolling ovality' in the kiln shell.
