Abstract

A cooler for cooling bulk material, such as cement clinker, for example, may include an aeration floor through which cooling gas can flow. The aeration floor may be configured to receive bulk material and to transport the bulk material in a conveying direction. The aeration floor comprises a plurality of conveying beams that are mounted so as to be movable in the conveying direction and counter to the conveying direction. A seal is mounted between two adjacent conveying beams, and the seal has at least two sealing elements mounted so as to be movable relative to one another. The sealing elements each have a sealing profile, which interact with one another such that a sealing gap is formed between them. The sealing gap has a double or multiple U-profile.
