Abstract

This process consists of three main stages:- <DL TSIZE=8> <DT>Stage 1<DD>Cooling <DT>Stage 2<DD>Crushing <DT>Stage 3<DD>Separation </DL> <H1>Stage 1</H1> The tyre is exposed to a rapid cooling agent (liquid nitrogen or some other substance capable of producing a similar effect) in order to render the tyre brittle. <H1>Stage 2</H1> The tyre is then crushed or impacted to break it down to a granular/powder form. <H1>Stage 3</H1> The residue from Stage 2 is exposed to a magnetic field in order to separate the bulk of the steel granules from the rubber granules.

Description

VEHICLE TYRE RECYCLING PROCESS SPECIFICATION This process brings together a number of functions in order to provide a means of separating the major basic materials used in the manufacture of vehicle tyres in order to make them more available for recycling.

Claims (1)

  1. CLAIMS By bringing together known elements of technology in a new sequence, in order to provide a method, which enables the separation of the major basic materials used in the manufacturing of vehicle tyres.
    Note 1: The sequence outlined in the abstract is crucial to the success of the process: a. The cooling of the tyre to the point where it is brittle enough to allow the structural integrity of the tyre to be destroyed is essential. b. The crushing to a granulated/powder form is now possible and again essential. c. The primary separation using a magnetic field is now possible, but only after the first two stages have been completed.
    Note 2: No attempt has been made to describe specific types of machinery/equipment needed in this process, because it is recognized that more than one type is already available capable of satisfying each of the required stages.
