Clinker production in rotary kiln system is the most energy intensive stage in cement production, accounting for about 90 of total thermal energy use 8.
The system consists of calculating the kiln distortion induced by temperature changes over the shell in order to infer the cyclical overloads and associated stresses suffered by the shell, tyres and roller stations. The kiln thermo-mechanical distortion is calculated in real time from the shell thermal map drawn up by the shell infrared scanner.
