The method comprises supplying rubberized steel-cord in a separation device (5), where the steel-cord material (1) is given for the separation into the separation device, supplying powdery separation agent (3) into the separation device, separating the steel cord and rubber coating through the cooperation of a rotating tools and the separation agent into the separation device, wrapping the rubber particles to be separated with the separating agent and supplying the rubber particles from an opening into the separation device. The method comprises supplying rubberized steel-cord in a separation device (5), where the steel-cord material (1) is given for the separation into the separation device, supplying powdery separation agent (3) into the separation device, separating the steel cord and rubber coating through the cooperation of a rotating tools and the separation agent into the separation device, wrapping the rubber particles to be separated with the separating agent and supplying the rubber particles from an opening into the separation device. The powdery separation agent possesses a specific weight slighter in the ratio to the steel cord. The separation agent is polyurethane powder, talcum, chalk, sawdust or other powdery separation agent, by which the rubber particles to be separated are wrapped and fasten its surface. The separating agent is added in a quantity of 20 wt.% of the rubberized steel-cord to be separated to the separation device. The rotating tools are chains (2), which rotate with a number of revolutions of 350-750 revolutions per minute. The separating device is a drum machine. The rubberized steel-cord material is standard material in the form of steel cord waste, green tire and carcasses, which occur in the tire manufacture. The steel cord material is taken after the separation of the rubber from the separation device and is brought out after the separation of the rubber through an opening in the separation device. |
