A rotary kiln has a plurality of outlets to pass material from within the kiln to associated cooler tubes that are mounted in use in a 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 wearresistant ceramic material. An annular collar, formed of the same material as the ring, extends radially beyond the joint between the support and the kiln shell.
