Beschreibung
Zusammenfassung:	The invention relates to a cooler for cooling hot bulk material, wherein cooling gas flows approximately transverse to the feed direction through a bulk material bed, and absorbs the heat of the bulk material, wherein a fixture supporting the bulk material bed comprises a ventilation base through which the cooling gas flows, and wherein the feeding principle provides planks extending in the feed direction, wherein at least two adjacent planks are displaced in the feed direction at the same time and opposite the feed direction at different times. According to the invention, the planks comprise differently designed surfaces in the feed direction, on which the bulk material bed is supported, causing different average transport speeds due to the different frictional fits with the supported bulk material bed, so that the bulk material bed is thereby extended in the area of the faster feed and is compressed in the area of the slower feed. The fixture churns the bulk material to be cooled by means of vertical mixing, whereby the heat recuperation becomes more efficient.
