A cooler for hot material such as cement clinker which includes a plurality of superimposed heat exchanger sections. Each of the sections includes an arrangement such as a series of alternately fixed and movable grates for moving material from the inlet of the section to the outlet of the section. A material breaker is positioned between the initial heat exchanger section and the second heat exchanger section. A material lock is provided between each section. The material is cooled by air flowing upwardly through the grate and material. Cooling air is introduced into a plenum chamber beneath the last section, flows upwardly through the material in that section and through the material in the succeeding sections and is eventually sent to the furnace as heated combustion air. Before passing through the initial section, water may be sprayed into the air to cool the same.
