• a cooling gas chamber through which a cooling gas stream for cooling the bulk material is configured to flow crosscurrent, wherein the cooling gas chamber comprises:
• a first cooling gas chamber portion with a first cooling gas stream, and
• a second cooling gas chamber portion with a second cooling gas stream, the second cooling gas chamber adjoining the first cooling gas chamber portion in a conveying direction of the bulk material;
• a conveying device for conveying the bulk material through the cooling gas chamber in the conveying direction;
• and
• a separating apparatus for gastight separation of the cooling gas chamber portions from one another, wherein the separating apparatus extends transversely with respect to the conveying direction and has a suspension element to which sealing elements are attached, wherein the sealing elements are arranged next to one another such the sealing elements cover a cross section of the cooling gas chamber.
