A rubber tire component reclamation technique which provides tire rubber fragments classified according to size. Preferred apparatus for rubber tire component reclamation includes a feed hopper for receiving pieces of discarded tires, a granulating chamber coupled to the feed hopper for cutting the received pieces into smaller fragments, and an exit chute providing an output from the granulating chamber through which tire fragments fall. An air flow is induced upwardly through the exit chute to urge the less dense components such as yarn and fabric upwardly against gravity and out of the upper portion of the chute. The air flow is of sufficient force to prevent commingling and compaction of the less dense components with the remaining components of the tire fragments. A magnetized drum is located near the lower end of the exit chute for segregating the ferromagnetic components of the tire fragments. A fragment classifier receives the fragments which are not trapped by the magnetic drum and segregates those received fragments into at least two, and preferably three, separate groups according to fragment size.

The method of separating rubber from other components of castaway tires comprising the steps of: debeading the tires to remove any steel tire bead; granulating the tires to form tire fragments including lighter-than-rubber components and ferromagnetic components; separating the lighter-than-rubber components from the tire fragments as those fragments emanate from the granulating step and prior to the tire fragments coming to rest on any fixed surfaces by causing the tire fragments to free fall downwardly after granulating and simultaneously providing an upwardly directed air flow into the falling tire fragments; subsequently separating the ferromagnetic components from the tire fragments; and classifying the remaining tire fragments by segregating them into at least three groups according to size. Apparatus for rubber tire component reclamation comprising: a feed hopper for receiving pieces of discarded tires; a granulating chamber coupled to the feed hopper for cutting the received pieces into smaller tire fragments; an exit chute coupled to said granulating chamber for providing an output from the granulating chamber through which the tire fragments fall, said exit chute comprising a tapered housing having a relatively wide mouth at an upper end thereof adjacent the granulating chamber for receiving the tire fragments from the granulating chamber and a relatively small opening at a bottom end thereof through which tire fragments fall, and a tapered baffle within the housing, said tapered baffle extending from the upper end of the housing and extending said mouth separating the mouth from an upper exit portion of the chute including at least one opening in the upper portion of the housing through which less dense components exit; means for inducing an air flow upwardly from said small opening through the exit chute to urge the less dense components upwardly against gravity and out of the upper exit portion of the chute, the air flow being of sufficient force to prevent commingling and compaction of the less dense components with remaining components of the tire fragments.
