ABSTRACT:
The invention relates to a method and means for cooling lump material in which the material in a vertical, gas-tight cooler (1) is subjected in a furst step to a transverse cooling flow (at 9) and in a second step to counter-flow cooling (at 20). Optimal cooling effect is obtained by a distribution of the cooling gas between transverse and counter-flow cooling in such a way that maximum temperature is obtained in the cooling gas leaving through the outlet (13).
