Title (EN) METHOD AND APPARATUS FOR RECOVERING ELASTOMERIC MATERIAL
(FR) METHODE ET PROCEDE DE RECUPERATION DE MATIERE ELASTOMERE
Abstract:
(EN) A method for recovering elastomeric material such as rubber from tyres comprising the steps of soaking the tyres in a mixture of liquids in tanks which soften the rubber, subjecting the softened tyres to shear conditions to the rubber, and recovering the rubber and drying it in a drier. In this method grinding of the tyre is not required. The recovered dried rubber can be carbonized in a microwave chamber to form a substitute for products such as carbon black formed by burning fossil fuels. A screw conveyor provides the preferred means to remove the softened rubber by a shearing action.
(FR) Méthode de récupération de matière élastomère telle que du caoutchouc à partir de pneus incluant les processus de trempage des pneus dans un mélange de solvants liquides dans des réservoirs pour ramollir le caoutchouc, de cisaillage des pneus ramollis pour enlever le caoutchouc et de récupération du caoutchouc pour le sécher dans un dessiccateur. Avec cette méthode, il n'est pas nécessaire de meuler les pneus. Le caoutchouc séché récupéré peut être carbonisé dans une chambre à micro-ondes pour former un substitut de produits tels que le noir de carbone résultant de l'incinération de combustibles pétrolifères. Une vis transporteuse constitue le meilleur moyen de séparation du caoutchouc ramolli par cisaillage.
