Abstract

To reduce plastics and rubber waste materials, and especially used vehicle tyres, they are initially chopped to an intermediate particle size, to be frozen. The frozen particles are further reduced, preferably by grinding.

Description

Bei der Entsorgung bzw. beim Recycling von Gummi- und Kunststoffabfällen, insbesondere Autoreifen wurde das Material bis zur Brüchigkeit tiefgekühlt und in diesem Zustand fein zerkleinert. Dieses Verfahren hat sich als nicht wirtschaftlich erwiesen.In the disposal or recycling of rubber and Plastic waste, especially car tires, became that Frozen material to the brittle and in it Condition finely crushed. This procedure has proven to be not proven economically.

Aufgabe der Erfindung ist es diese Nachteile des Stan­ des der Technik zu vermeiden.The object of the invention is these disadvantages of the Stan to avoid the technology.

Erfindungsgemäß werden ggf. die vorgenannten Materia­ lien zunächst mechanisch auf kleinere Stück- bzw. Korn­ größe, beispielsweise in Größen von ca. 5 cm Stückgröße zerkleinert, vorzugsweise auf 1, 2 oder 3 cm oder grobe Körner von ein oder mehreren Millimetern Durchmesser zerkleinert, ggf. unter Trennung von Fremdbestandteilen (Metall- und Stoffeinlagerungen), und erst in diesem zerkleinerten Zustand tiefgekühlt und dann weiter zer­ kleinert, z. B. gemahlen, wobei jede denkbare Feinheit des zerkleinerten bzw. zerpulverten Materials, und damit z. B. auch ein Recycling bei der Gummi-Neuherstel­ lung von Reifen möglich ist. According to the invention, the aforementioned materials may be used first mechanically on smaller pieces or grain size, for example in sizes of approx. 5 cm piece size crushed, preferably to 1, 2 or 3 cm or coarse Grains one or more millimeters in diameter crushed, if necessary with separation of foreign components (Metal and fabric storage), and only in this shredded frozen and then further crushed diminishes, e.g. B. ground, with every conceivable delicacy of the crushed or pulverized material, and z. B. also recycling at the new rubber product tire is possible.  

Die in der ersten beispielsweise z. B. mechanischen Zerkleinerungsstufe auch z. B. durch Wasserstrahlschnei­ den erreichte kleinere Stückgröße kann in der Tiefkühl­ phase, eng mit flüssigem Stickstoff vermischt werden und kälte- bzw. wärmeisoliert tiefgekühlt werden, wobei die tiefgekühlten Teilchen vom Stickstoff getrennt werden und diese nach erneuter Abkühlung bzw. Wärmeentzug wieder verwendet werden.The in the first example, for. B. mechanical Shredding stage also z. B. by water jet snow The achieved smaller piece size can be frozen phase, be mixed closely with liquid nitrogen and be insulated from cold or heat, whereby the frozen particles are separated from the nitrogen and after cooling again or Heat extraction can be used again.

Statt flüssigem Stickstoff kann auch ein anderes, nicht so tiefgekühltes Material verwendet werden, beispiels­ weise festes Kohlendioxyd bei Temperaturen von ca. minus 40-70°C jeglicher Art z. B. auch in Pulverform, zur intensiven Vermischbarkeit bzw. Kontaktierbarkeit mit dem vorzerkleinerten Zwischenstufenmaterial. Dabei können Kohlensäurepulver oder Granalien mit den Recycling- bzw. Gummi-Partikeln eng miteinander in Kontakt gebracht oder verquetscht oder miteinander zermahlen werden.Instead of liquid nitrogen, another one can not frozen material can be used, for example wise solid carbon dioxide at temperatures of approx. minus 40-70 ° C of any kind z. B. also in powder form, for intensive miscibility or contactability with the pre-shredded intermediate stage material. Here can use carbon dioxide powder or granules Recycled or rubber particles closely related to each other Contacted or squeezed or with each other be ground.
