ABSTRACT:
A continuous process for reclaiming rubber, steel and fiber products from tires wherein the tires and tire material flow on conveyors throughout the various steps of the process, including the steps of shredding a flow of whole tires into pieces in a shear-type shredder, and screening the flow of tire pieces by size into a first flow containing pieces at least as large as a specified size, and a second flow containing pieces under a specified size. Reshredding and rescreening the pieces of the first flow is performed until they are smaller than the specified size. Granulating the pieces of the second flow occurs in a first granulator wherein the pieces remain in the granulator until they are reduced below a second specified size. Fiber materials are vacuumed from the flow of granulated material with an air separator after granulation and steel and steel-containing rubber pieces are removed from the flow of material via a magnetic separator after the fiber materials have been removed.
