Abstract
A rotary kiln having a plurality of outlets for passage of material from within the kiln to associated cooler tubes mounted in use in planetary fashion around the outlet end of the kiln. Each kiln outlet has a tubular support to which the inlet end of the associated cooler tube is attached, and a steel reinforcing ring within the support. Insulation is provided between the ring and the support and the ring is lined internally with a wear-resisting ceramic material. An annular collar is formed of the same material as the ring and extends radially beyond the joint between the support and the kiln shell. The collar--which is bolted to the kiln shell--is insulated from both the support and the kiln shell and is coated with a wear-resistant ceramic material.
