Summary:
The goal of this work is to demonstrate a novel pulverization process known as solid-state shear extrusion (originally
developed in the former USSR) for used tire recovery.  Whole tire products and tread tires have been successfully
pulverized into fine powder of different particle sizes and size distribution.  The powder which is formed by shear
deformation under pressure coupled with an extensive cooling has unique particle shape and morphology and is
somewhat reactive.  This novel pulverization process is both technically and economically superior to other know tire
grinding processes.
