| 1. A device for shredding wornout tires, comprising:
an armored chamber having side walls;
a compact tire package arranged coaxially in said armored chamber and having a center hole for accommodating explosive charge;
said compact tire package made up of a number of coaxially arranged one upon another helical twists;
each of said helical twists made of a number of helically twisted raw blanks put one onto another;
each of said raw blanks appearing as a band made up of one worn-out tire by separating metal bead ring and cross-cutting of
said wornout tire;
free space established between the inner surface of said side walls of said armored chamber and the outer surface of said
compact tire package intended for providing free radial expanding of said compact tire package under the effect of explosion
prior to forming a stress-strain distribution of the material of said compact tire package, providing destruction and shredding
said material of said compact tire package into finely divided fractions sizing 1 to 6 mm free from metallic inclusions;
said free space limited to said inner surface of said side walls of said armored chamber has a diameter which in any cross
section square with the chamber longitudinal axis and passing through the compact tire package varies from 2 to 7 compact
tire package diameters in said cross section;
a means for loading a compact tire package into said armored chamber and a means for arranging said package therein;
a means for accommodating explosive charge in said center hole of said compact tire package;
a means for initiating an explosion arranged in said explosive charge;
a means for withdrawing the explosion products; and
a means for unloading the products of shredding said compact tire package.
