The invention relates to the recycling of worn-out tyres and other industrial and domestic wastes. The method for disintegrating the worn-out tyres consists in producing a package of worn-out tyres in the form of compressed layers. The initial destruction of said package is carried-out in an armoured chamber in conditions of free extension until a destruction point of the external layers thereof is reached. The dimensions of the armoured chamber at any section perpendicular to the axis thereof and vary within a range of 2 to 7 times of diameter of the package in said section. The package of tyres is formed from several spiral twists which are axially arranged and provided with an axial orifice. Deformation and a state of stress are produced during the free extension of the rubber layer without contacting the walls of the armoured chamber. Said state makes it possible to carry out the effective destruction and disintegration of the rubber and metallic and textile cord.
Cette invention porte sur le recyclage de pneus usés et autres déchets industriels et domestiques. Ce procédé de recyclage consiste à former un bloc de pneus usés sous forme d'un empilement de couches serrées. La destruction initiale du bloc s'effectue dans une chambre blindée dans des conditions d'extension libre jusqu'au moment de destruction des couches périphériques. La chambre blindée, dans n'importe quelle section transversale du bloc de pneus et perpendiculaire à l'axe de la chambre, représente entre 2 et 7 fois le diamètre du bloc de pneus dans cette même section. Le bloc de pneus est constitué de plusieurs spirales s'enroulant axialement et formant un orifice axial. Selon cette invdention, on obtient un état de déformation et de tension lors de l'extension libre de la couche de caoutchouc sans qu'il y ait contact avec les parois de la chambre blindée, ce qui permet de broyer et détruire efficacement le caoutchouc et la corde métallique et textile.
