A method is disclosed for intensifying the cooling of hot granular material exiting from a series of cooler tubes mounted in planetary fashion around a rotary drum by introducing a cooling liquid into the cooler tubes in a manner such that the liquid contacts the hot granular material as it passes therethrough and the heat of evaporation of the liquid intensifies the cooling of the material. A planetary cooler system for cooling material exiting from such cooler tubes is also disclosed in which means is provided for introducing cooling liquid preferably in the form of a spray so as to contact the material exiting from the cooler tube and intensify the cooling of the granular material as it passes through the cooler tubes. |
