ABSTRACT:
An annular cooler for a rotary kiln having a series of tubes longitudinally extending parallel to the axis of kiln and radially spaced therefrom. The tubes have flights mounted therein for carrying and moving clinkers discharged from the lower end of the kiln into the tubes and then upward to the upper end of the tubes where they are discharged into an appropriate collecting bin. A cooling medium is drawn downward through the tubes opposite to the direction of travel of the clinkers. The cooling medium which is heated as it travels through the tubes is directed into the kiln upon leaving the cooling tubes for use in the combustion process in the kiln.
