Abstract: Method and device are for recycling wornout tires and other industrial and domestic wastes. According to a method for shredding wornout tires a package of wornout tires is formed as a number of closely compacted layers. The package is subjected to primary destruction in an armored chamber under conditions of free extension until the package outside layers are destroyed. The overall dimensions of the armored chamber in any cross-section thereof perpendicular to the chamber axis and passing through the package of the compacted tires varies within the range of from 2 to 7 package diameters in such section. The compact package of tires is formed from a few coaxial helical twists having an axial hole. Accordingly, a stress-strain state is established upon free extension of a rubber layer without its contacting with the walls of the armored chamber, whereby efficient destruction and disintegration of the rubber, metallic and textile cord of a tire is attained.

Abstract: The invention relates to recycling wornout tyres and other industrial and domestic wastes. According to a method for shredding wornout tyres a package of wornout tyres is formed as a number of closely compacted layers. The package is subjected to primary destruction in an armored chamber under conditions of free extension until the package outside layers are destroyed. The overall dimensions of the armored chamber in any cross-section thereof square with the chamber axis and passing through the package of the compacted tyres varies within the range of from 2 to 7 package diameters in such section. The compact package of tyres is formed from a few coaxial helical twists having an axial hole. According to the invention, a stress-strain state is established upon free extension of a rubber layer without its contacting with the walls of the armored chamber, whereby efficient destruction and disintegration of the rubber, metallic and textile cord of a tyre is attained.

Abstract: The method for shredding wornout tire cases comprises exposing wornout tire cases to the effect of an explosion exerted thereon in a closed circular system so as to establish a directional circulating flow of explosion products. The device for carrying the method into effect comprises a chamber (1, 2) and a piping (3, 4) which forms, together with the chamber, a circular closed system, the chamber has a portion shaped as a cone-frustum shell (1), wherein shredding members (7) and a fixing unit of the explosive (13) are accommodated; a the smaller-diameter portion of the cone-shaped shell (1) communicates with one end of the piping (4) through a valve appearing as, e.g., a grid established by plates (7) in the area of the smaller base of the shell (1), while the other end of the piping (3) communicates with the chamber (1, 2) from the side of the larger-diameter portion of the cone-shaped shell (1).
