Cooling tubes are secured to a tubular rotary kiln in circumferentially spaced relationship for movement with the kiln about the kiln axis. A longitudinally terminal part of each tube is connected with an axial end portion of the kiln by a radial duct so that the terminal tube part receives hot, processed material from the kiln by gravity when the tube is located below the kiln. A deflector in the tube deflects previously received material into the path of the hot material dropping from the duct into the tube when the tube approaches its position below the kiln, thereby protecting the inner tube wall against the impact of the hot, discharged material, and preventing rapid wear of the refractory tube lining. |
