gain in strength between room temperature and 200 C, followed by a sharp loss in strength as the temperature goes up. At 430 C the ultimate strength of the steel drops from 75,000 psi to 50,000 psi (a hefty 33%) loss. Some investigators report a 50% strength loss for the same temperature range. Figure-1: Kiln shell strength as temperature raise

Tasek cement plant in Malaysia aims to monitor the overall temperature of their 500 tpd rotary kiln no 3 to prevent any interruption in production due to hot spots.The cement plant shows a complex layout including many posts and pillars masking the shell. A portion of the kiln is also located under a building. These obstructions prevent the IR scanner from seeing the entire kiln shell and

Jun 01, 2017 The past two years of operation have shown that cement plants that suffer from temperature problems on the kiln shell were able to prolong kiln runtimes for weeks or months by using the KIMA KilnCooler. The system can take care of hot areas and keep the temperature within those areas at the desired set point temperatures

The original rotary cement kilns were called 'wet process' kilns. In their basic form they were relatively simple compared with modern developments. The raw meal was supplied at ambient temperature in the form of a slurry. A wet process kiln may be up to 200m long and 6m in diameter

The makeup of a kiln. During the operation of the rotary kiln, flames can reach temperatures as high as 1900 C (3452 F) in order to heat raw materials to roughly 1500 C (2732 F). As a result, these materials become partially molten and undergo a series of physical and chemical reactions to become the primary constituent of cement

Aug 14, 2021 Aug 14, 2021 Kiln Burning Zone Temperature Measurement - The Kiln is the heart of the plant – what an entire cement plant is dimensioned around, and where most of the final chemical reactions take place. The kilns play a key role in ensuring optimal quality clinker. The rotary kiln consists of a tube made from a mild steel plate and slowly rotates on its axis
