ABSTRACT:
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 thereof are provided with a plurality of substantially longitudinal slots which accommodate circumferential expansion and the refractory is affixed to the steel shell at such end(s) with sliding anchors to accommodate longitudinal expansion.
