In a method of treating composite elements of solid organic and/or inorganic composite substances - such as metal/metal, plastics/plastics or metal/plastics composites or mineral composites containing metals and/or plastics - solid particles are produced from the composite elements and added to a conveying fluid. At least one flow obstacle, such as a separating edge, disposed transversely to the flow of the mixture of solid particles and conveying fluid, is moved relative to said flow in order to form eddies which accelerate and break up the mixture. The mixture is fed to the separating or breaking-up process at the separating edge(s) at an acceleration of 20 to 60 m/sec2, and the composite element preferably is desintegrated before the separating or breaking-up process.

Procédé de traitement d'éléments composites formés de matériaux composites solides organiques et/ou inorganiques, tels que des composites métal/métal, matière plastique/matière plastique, métal/matière plastique, ou des composites minéraux avec des métaux et/ou des matières plastiques, consistant à produire, à partir des éléments composites, des particules de matière solide et à introduire celles-ci dans un fluide de transfert, caractérisé en ce que, par rapport au courant du mélange formé par les particules de matière solide et le fluide de transfert, au moins un obstacle s'opposant à ce courant est déplacé, sous la forme d'un bord de séparation, pour la formation de tourbillons désagrégeant le mélange de façon accélérée. Le mélange est acheminé de manière à parvenir au processus de séparation ou de désagrégation, sur le/ou les bord (s) de séparation, avec une accélération de 20 à 25 m/sec<2>, l'élément composite étant de préférence fragmenté avant séparation ou désagrégation.
