A cooler (1) is disclosed for cooling particulate material which has been heat-treated in an industrial kiln such as a rotary kiln (3) for manufacturing cement clinker. The cooler has an inlet end (4), an outlet end (5), end walls (6, 7), side walls (8), a bottom (9) and a ceiling (10). At least one supporting surface (11) for supporting the material to be cooled is provided, as well as means (11a, 12) for injecting cooling gas into the material, and means (14) for conveying the material forward across the supporting surface from the inlet end (4) to the outlet end (5). An inlet section (20) is fitted in the inlet end for receiving the material from the kiln and for distributing this material on the supporting surface. The inlet section means (20) distributes the material which is received from the kiln across the cooler in directions towards the side walls of the cooler. Thus it is possible to extend the width of the cooler without having to extend the inlet section correspondingly, due to the fact that the material can be distributed in a better and more uniform manner also in the width direction of the cooler. The wear rate of the moving parts is reduced because the velocity of the conveying means can be reduced and, furthermore, a better heat exchange between the clinker and the cooling gas in the inlet zone is achieved because the thickness of the protective layer of the stationary clinker on the inlet surface can be better adapted. |
