Abstract: A method can be used to cool bulk material in a fine material cooler. The method may involve admitting bulk material to be cooled into the fine material cooler through a material inlet, conveying the coarse material with a first mechanical or pneumatic conveying unit, and conveying the fine material with a second conveying unit in a conveying direction through the fine material cooler to a material outlet. The bulk material may have a fine material proportion of 70% to 95% and a coarse material proportion of 5% to 30%. The fine material may have a grain size of 10-5 mm to 4 mm, and the coarse material may have a grain size of 4 mm to 100 mm.

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.

Abstract: A cooler for cooling bulk material, in particular cement clinker, may include a cooling gas chamber through which a cooling gas flow for cooling the bulk material can flow in crosscurrent, and a conveying device for conveying the bulk material through the cooling gas chamber in a conveying direction. The cooling gas chamber may include a first cooling gas chamber portion with a first cooling gas flow and a second cooling gas chamber portion, adjoining the first cooling gas chamber portion in the conveying direction of the bulk material, with a second cooling gas stream. The cooler may include a separating apparatus for gastight separation of the cooling gas chamber portions from one another. The separating apparatus may have sealing element and at least one suspension element, to which a plurality of sealing elements are attached.
