Abstract

A rotary kiln having a row of planetary cooler tubes disposed around its outer periphery and carried by individual metal mountings on the kiln casing, adjacent mountings abutting against each other in their areas bordering on the kiln casing and being spaced apart in their areas remote from the kiln casing, for minimizing changing temperature induced stresses imparted therefrom to the kiln casing during operation.
