Abstract (en)
[origin: EP0442790A1] Cold and wet aggregates (4) are continuously introduced into a drying zone (7). The aggregates and hot gases are circulated countercurrentwise in the drying zone (7). The dried and heated aggregates are continuously introduced into a mixing zone (16) through which the hot gases do not travel. Liquid bitumen is incorporated into the aggregates in the mixing zone (16). The aggregates are circulated and they are mixed with the bitumen during their circulation in the mixing zone (16). During coating, the aggregates are kept in the mixing zone (16) during certain phases at least of production, by closure of a discharge means (21) communicating with the exit from the mixing zone (16). <IMAGE>
