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.
