    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.
