Abstract (en)
[origin: EP1306636A1] Process for uniformly heating a mixture comprising coarse and fine grains using a hot gas flow involves introducing into the hot gas flow the grains at different positions depending on their size, so that the grains cover a distance which increases in length with increasing grain size. <??>An Independent claim is also included for a device for carrying out the above process. <??>Preferred Features: The grain mixture is introduced with the aid of a backward-flowing carrier gas flow into a forward-flowing hot gas flow, so that ,before transfer into the hot gas flow, the grains are separated depending on their size, with the smaller grains being introduced higher up in the hot gas flow than the larger grains.
