Abstract

The cooling apparatus which is preferably constructed in the form of a grate cooler contains in its material inlet portion a material transfer arrangement with at least two rows lying behind one another of transversely extending air boxes which can be supplied with air and have upper surfaces with air holes. The clear opening width of these air holes (area for the air to pass through) is adjustable, so that all air boxes can be supplied independently of one another with adjustable quantities of air. In this way the streams of cooling air can be adapted to differing local ranges of grain sizes of the clinker on the material transfer arrangement.
