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.
