Abstract
In processes for making carbon black from automobile tires containing fiberglass, or the like, a mat of fiberglass strands intertwined with carbon black trapped in the interstices thereof can be produced. The present invention discloses method and apparatus of producing useful fiberglass and carbon black from such mats. Rapid agitation breaks the mat into a cloud of fine fiberglass particles and free carbon black. A low velocity airstream carries the particles to a separation zone wherein the free carbon black is filtered from the airstream as a first useful by-product. The fiberglass particles are then combusted to remove remaining carbon black carried therewith thus forming a second useful by-product.
