Failed Rotary Cement Kiln During Startup. We performed a failure investigation on an accident involving a cement kiln during the startup. Problems with the conveyor system feeding the kiln had occurred, and the kiln heatup was suspended. One day later, heatup resumed, but hot spots were observed on the kiln shell, indicating problems with the

Jan 07, 2020 The rotary kilns feature is lateral movement. Axial movement of the shell. The main reason for this is the thermal expansion of shell which reposition tires on the stationary rollers. The problems appear when the running surfaces are not perfectly cylindrical. Any axial position changes bringing additional excessive stress to working components

Oct 24, 2012 Avoiding the formation of rings in rotary kilns is an issue of primary concern to the cement production industry. We developed a numerical combustion model that revealed that in our case study rings are typically formed in zones of maximal radiative heat transfer. This local overheating causes an overproduction of the liquid phase of the granular material, which tends to stick to the oven’s
