Abstract

Method of recycling tyres or other discarded rubber products, so as of conveyor belts, where the tyres supplied are sorted and checked, then the tyres are separated into beads (5) with the wire beads, sidewalls (4) and tread (3) by water jet in the first stage, the separated sidewalls (4) and tread (3) are separately conveyed to the second stage of cutting by water jet to pieces of uniform size, the cut pieces are frozen, then crushed to a mixture of structure with fully separated individual fractions, the mixture is left to settle down and is then sorted to individual fractions, i.e. textile lint, metal, rubber granulate, and eventually, the finest textile fluff is removed from the final granulate. Equipment for recycling comprises a device for controlling of liquid nitrogen level height in the freezing chamber. Crushing knife for crushing of material in a chamber has a convex or concave form formed by a part of logarithmic spiral or Archimedes' spiral or by a part of a circle evolvent.
