ABSTRACT:
A rubber crumbing apparatus and method for making crumb rubber from tire chips is disclosed. The rubber crumbing apparatus comprises a frame assembly, a first cone assembly including a truncated cone having an interior surface and an opening extending therethrough, and a second cone assembly positioned substantially within the first cone assembly. The second cone assembly includes a truncated cone having an exterior surface in opposing relationship to interior surface of the first truncated cone. The second cone assembly rotates relative to the first cone assembly. A plurality of crumber blades are connected to one of the opposing surfaces and a plurality of beads are attached to the other opposing surface of the truncated cones. The crumber blades are in close proximity to said beads without contacting said beads as the second cone assembly rotates relative to the first cone assembly. Tire chips are fed between the truncated cones. The close proximity of the crumber blades and the beads as the second cone assembly rotates tears the rubber from the tire chips to make crumb rubber.
