Abstract
In order to provide, for a grate cooler for cooling hot bulk material, such as, for example, cement clinker, an, in particular, automatically operating cooling air regulator which has a simple construction and can be used without difficulty both for unmoved and, in particular, for moved cooling grate regions or moved cooling grate systems, for example, cylindrical hose sleeve comprised of elastic material be tension-mounted as an actuating member coaxially in the regulator housing which is arranged below the cooling grate, participates in the movements of the latter and has a casing comprised of solid material, the pressure difference inside and outside the hose sleeve and the deformation resistance of the sleeve being set such that the hose sleeve is deformable, in particular, automatically from its maximum flow cross section into its minimum flow cross section and at the same time regulates the volume flow of the cooling air flow from below into the cooling grate.
