Abstract: A device for processing scrap rubber has a reactor with a screw conveyor disposed inside a heating chamber, a thermal decomposition unit, burners, a condenser, a cyclone filter, and devices for discharging solid residue and removing a gas-vapor mixture. The reactor has two sections connected in parallel. The thermal decomposition unit has screw conveyors in each section, the conveyors have axial heating pipes with a coil. Along the length of the conveyors plates are arranged at the corners of an equilateral triangle in contact with and perpendicular to the side surface of the heating tube. A cylinder furnace with an evaporator and a burner is connected to the ends of the pipes. An outlet of the condenser is connected to a liquid fraction separator, inlets of the coils are connected to an outlet of the evaporator, and an inlet of the evaporator is connected to an outlet from the separator.
