Cement Kilns: Design features of rotary kilns
The early commercially successful rotary kilns in Britain were nearly all "straight" cylinders, the exceptions being those at Norman (1904). Lengthening of the early kilns at Wouldham and Bevans resulted in kilns with enlarged burning zones, while the lengthened kilns at Swanscombe had enlargements at both ends. Among new installations from 1909 to 1914, only 15 out of 44 were .
Failure Analysis of Rotary Cement Kiln During Startup
Rotary kilns run 24/7 and are stopped only for a few days for essential maintenance. This is important because of heatup and cool down thermal transients. The process of starting a rotary kiln is complex – thermal differences between components must be carefully controlled to avoid the introduction of high thermallyinduced stresses that can cause damage.
