Process for cooling cement clinker in a grate cooler having a housing, a grate surface, and valves, sliders or lattice arrangements as dosing devices for introducing the cooling gas stream comprises controlling the dosing devices by an adjustable drive arranged in the transporting direction. Preferred Features: Only the fixed grate plates are provided with the dosing devices. A regulating circuit is used to control the adjustable drive, where the temperature is determined at certain points in the grate cooler.
