Abstract (en)

[origin: WO0177600A1] The invention relates to a cooler (1) and a method for cooling hot bulk material (2). The hot bulk material is charged onto a stationary aeration bottom (3) that can be flown through by cooling gas and is transported by means of conveying elements that are arranged above the aeration bottom and can be moved to-and-fro. At least two groups of conveying elements (4, 5, 6) are used which are actuated in a combined manner in the transport direction (9) and separately from one another against the transport direction.
