tire recovery method and a device for carryng out said method

摘要

A method for the recovery of tires, mainly waste tires, comprises feeding waste tires into a pyrolysis column; their exposure to an alternating magnetic field for heating them up to a rubber thermal decomposition temperature; removing volatile products formed in the rubber thermal decomposition process; cooling fixed residues of thermal decomposition products; and removing them out of the pyrolysis column. The tires are previously divided into parts, which parts are fed then into the pyrolysis column through a charging opening, and the induction heating of the tire parts is performed by inducing induced currents in a metal cord of the tire parts with an alternating magnetic field of between 1 kHz and 1000 kHz in frequency. The present invention relates also to a device for carrying out this method.
