Abstract
A cooler (1) for cooling particulate material from a kiln, wherein the material upon entry into the cooler (1) is distributed to a material bed on a stationary supporting surface (11) in the form of a tray, while cooling gas, such as atmospheric air, is blown up through the material bed from injectors in the tray in a uniform and evenly distributed manner. The material is conveyed forward across the supporting surface (1) and through the cooler (1) by means of a separate mechanical conveying device (17). It is thus possible to split the three functions of such a cooler, viz. to support the material, to distribute the cooling gas across the supporting surface and to convey the material forward across the supporting surface, into functions which are independent of one another, so that each function can be optimized.
