Analysis and replacement practice of cracking on the cylinder body of a rotary kiln with a diameter of Φ4.3 m×62 m
During the production process of a 2 500 t/d rotary kiln in a cement production line,a cylinder cracking occurred.After the cylinder cracked,the material was stopped in a timely manner and the kiln speed was reduced to 0.4 r/min,gradually cooling down and running.Measures to prevent the crack from continuing to expand were organized and implemented on site.At the same time,discus-sions were conducted on the cylinder repair plan,and the reasons for the cylinder cracking were analyzed.Finally,a plan to replace the cylinder was decided.The cylinder replacement plan was implemented on July 26,2023,and construction was completed on August 6,2023.Production was started on August 10.At present,the operation of the rotary kiln barrel is stable and has achieved the expected re-sults.
