The ends of refractory-lined rotary kilns are often subjected to such intense heat flux that the steel shell of the kiln at either or both ends is subjected to substantial thermal expansion in both the longitudinal and circumferential directions, resulting in premature cracking and failure of the refractory. The present apparatus is a rotary kiln wherein either or both ends of the steel shell

cementkilns: design features ofrotary 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 "straight", the
