Abstract
The invention provides an apparatus and method of its use, for recovering either devulcanized rubber or purified carbon and volatiles from a crumb rubber feed material. The apparatus comprises a chamber; a vacuum pump for providing reduced pressure within the chamber; an inlet for feeding crumb rubber into the chamber; an auger for providing continuous movement of the crumb rubber though the chamber; a battery of microtrons for providing substantially precise energy input into the crumb rubber as it is continuously moved through the chamber by the auger; at least one condenser for recovering volatiles from the crumb rubber after it has been sufficiently heated by said the microtrons; and an outlet for withdrawing either a devulcanized rubber or a purified carbon product residue from the chamber.
