  • Patent number: 9926426
    Abstract: Method of devulcanizing rubber and/or elastomers without the need for a chemical agent, in which method the vulcanized rubber and/or elastomers are fed into a planetary roller extruder, which planetary roller extruder has a housing, a central spindle, and at least one group of planetary spindles. Mechanical and thermal stress is generated on the vulcanized rubber and/or elastomers by kneading and/or crushing the vulcanized rubber and/or elastomers using the central spindle and the planetary spindles. The mechanical and thermal stress alone is sufficient to break or destroy the molecular chains or bonds of the vulcanized rubber and/or elastomers.

  • Patent number: 9193106
    Abstract: Method for producing a blend of a plastic first material and a wood or other plant second material in a planetary roller extrusion arrangement. The method involves feeding particles of the second material into a feed, which particles of the second material have a maximum diameter of 1 mm. Particles of the first material are fed into a melting device and liquefied into a plastic melt. The plastic melt is fed into a pump. Particles of the second material are moved into a planetary roller part of the extrusion arrangement, while the plastic melt is also pumped in. The particles of the second material are then blended with the plastic melt to form a blend that is at least 60% by weight of the second material.

  • Patent number: 8957119
    Abstract: Method of devulcanizing rubber and/or elastomers without the need for a chemical agent, in which method the vulcanized rubber and/or elastomers are fed into a planetary roller extruder, which planetary roller extruder has a housing, a central spindle, two groups of planetary roller spindles, and a dispersion ring disposed about the central spindle and between the two groups of planetary spindles. Mechanical and thermal stress is generated on the vulcanized rubber and/or elastomers by kneading and/or crushing the vulcanized rubber and/or elastomers using the central spindle and the planetary spindles, and by forcing the vulcanized rubber and/or elastomers through the dispersion ring, which is designated to substantially restrict passage of the vulcanized rubber and/or elastomers therethrough. The mechanical and thermal stress alone is sufficient to break or destroy the molecular chains or bonds of the vulcanized rubber and/or elastomers.
