<p>The aim of the invention is to create an automatic cooling air regulating device for a grate cooler for cooling hot bulk material such as cement clinker, that is easy to construct and easy to use both for fixed cooling grate regions and especially for mobile cooling grate regions or systems. To this end, the inventive regulating device comprises a regulator housing (11) which is arranged beneath the cooling grate, follows the movements of said grate, and through which the supplied cooling air (10) flows. An inner body (12) that can be displaced in a translatory manner by the cooling air flow is arranged in the regulator housing (11) in a displaceably guided manner. The flow cross-section of the regulator housing (11) remaining free for the cooling air (10) is automatically reached with the increasing height of the inner body (12) which is arranged inside the regulator housing and around which cooling air flows, and vice versa.</p> |
