Abstract
This invention relates to a rotary kiln for the heat treatment of material and having a number of elongate satellite cooling tubes distributed uniformly around the rotary kiln periphery at the exit end of the kiln, the inlet ends of these tubes being connected by short inlet pipes to the interior of the rotary kiln, and each tube being supported on the rotary kiln casing by two support bearings which accommodate axial movement of the tubes relative to the kiln occasioned by thermal expansion or contraction of the tubes. Mounting of the bearing means accommodates a close spacing between adjacent tubes.
