Definitions

  • the present invention in general, relates to a method of selective recovering components from multi-component elastic waste material, in particular from used vehicle tires, for the purpose of recycling
  • the method comprises grinding elastic components into fine-grained powder of elastic material, in particular into rubber powder, by using high-pressure water jet technology
  • the present invention also relates to an apparatus for producing fine-grained powder of elastic material, in particular rubber powder, which may be applied in said method
  • An alternative method of processing and recycling used rubber products comprises grinding rubber material into granulate or in special cases, into extra fine-grained rubber powder that may be utilized in paint industry, rubber industry and road construction depending on the grain size and the degree of purity of the resulted material.
  • mechanical cutting tools In order to grind or mill off the rubber material, mechanical cutting tools have been normally used which are exposed to extraordinary operating conditions due to changing characteristics of the rubber when heating. Although the cutting tool can be cooled, its cooling is very expensive and its wearing because of to the extreme heat is still significant. Deep-freezing the rubber material may ease grinding process, but high costs of this solution make it uneconomical.
  • Yet another disadvantage of mechanical grinding is that it is not possible to remove all of the rubber material from the remaining part of the rubber product, such as metal reinforcing inserts, i.e. cords, of the tires.
  • abrasive material is added to the high pressure water jet, which, on the other hand, results in strong wearing effect in the whole equipment and in particular in the water jetting nozzles. Moreover, abrasive additives contaminate the rubber granulate thus obtained, therefore its application is limited to special cases.
  • the main disadvantage of the above-mentioned method is that crumbling of all the rubber material from the steel cord is performed in one process, without separation rubber materials of different quality. In addition, this method does not allow to control the particle size of the crumbled rubber granulate.

  • the object of this method is to provide effective separation of different materials in order to obtain metallic clean cord material.
  • the separated rubber granulate so obtained also contains fabric cord residues deriving from the tires, therefore it can be mainly used to soak up oil-products and other chemicals. It is obvious that this method does not deal with selective separation of rubber materials, therefore rubber granulate produced by this method cannot be utilized in the paint industry and the rubber industry. Moreover, size of the particles of the rubber granulate cannot be controlled by this method either.

Abstract

L'invention concerne un procédé de récupération sélective de composants à partir d'une matière-déchet élastique multicomposée, notamment de pneus de véhicule usagés, aux fins de leur recyclage. Une fois la matière-déchet élastique multicomposée à traiter triée et découpée, des parties élastiques sont éliminées des composants les plus résistants sous forme de poudre de matière élastique, en particulier de la poudre de caoutchouc, par découpage au jet d'eau à haute pression. Cette poudre de matière élastique est alimentée séparément dans l'emplacement d'un traitement ultérieur où la poudre de matière élastique, notamment la poudre de caoutchouc recueillie à l'état humide au découpage, est soumise à une déshydratation et à un séchage avant sa mise en emballage. La poudre de matière élastique est éliminée de la pièce à travailler par découpage effectué avec des jets d'eau à haute pression qui se déplacent le long d'un trajet spatial positif. Le découpage s'effectue sous la forme d'une procédure de coupe et de déchirage réalisée dans des étapes ultérieures, à l'extrémité libre de la pièce à travailler, laquelle extrémité libre n'est pas posée sur un support. Pendant la découpe, les parties élastiques sont éliminées sélectivement de la pièce à travailler sur la base de leur qualité, puis triées et rassemblées séparément.
