Abstract
A method of reclaiming rubber from vehicle tyres that enables the high grade rubber in the tread portion of the tire to be collected separate from the lower grade rubber in the sidewalls and other areas of the tire. The method comprising separating the complete tread portion from the remainder of the tire and then removing from that tread portion the high grade tread rubber. Thereafter the remainder of the tread portion and the sidewall and bead portion of the tire are each treated to separate the rubber from metallic and fabric reinforcement materials therein. The high quality tread rubber and lower grade other rubber are both removed in a particulate form.
Claims6
A method of reclaiming rubber from a vehicle tire incorporating an annular tread portion having a metallic reinforcement belt underlying a layer of tread rubber, and respective sidewalls, said method comprising:
- separating the tread portion from the respective sidewalls and forming a tread portion strip;
- treating said tread portion strip to remove the layer of tread rubber from the reinforcement belt in a particle form;
- separately treating the tread portion strip to remove the remaining rubber from the reinforcement belt in a particle form, and
- separately treating the sidewalls to reduce the sidewalls to a particle form,
- the steps of treating the tread strip portion to remove the remaining rubber and the treating of the sidewalls each being performed independently of the step of removal of the tread rubber and each by the use of ultra high pressure liquid jets.
