Abstract

The process is effected at up to -169.99 deg C, and/or above -180 deg C using e.g. nitrogen. The feedstock comprises tires with rubber purity of up to 99.999% and rubber. A granularity of less than 50 mu m is reached. The process is effected at up to -169.99 deg C, and/or above -180 deg C using e.g. nitrogen. The feedstock comprises tires with rubber purity of up to 99.999% and rubber. A granularity of less than 50 mu m is reached. The rubber and pre-cooled rubber are cooled and ground, observing the foregoing process parameters.

Description

Die Erfindung bezieht sich auf ein Verfahren zur sauberen Trennung von Reifen und Gummi in ihre einzelnen Bestandteile unter Einsatz von Kälte und Fremdeinwirkung.The invention relates to a method for clean separation of tires and rubber in their individual components using of cold and external influences.

Unter Einsatz von Kälte - Abkühlen der Reifen bzw. des Gummis -, von bis zu -169,9°C und/bzw. (größer) < -180°C (z. B. durch Stickstoff) werden die in Reifen und Gummi enthaltenen Materialien durch zusätzliche Fremdeinwirkung (z. B. Mahlen, Schlageinwirkung) sauber in ihre einzelnen Bestandtei­ le (z. B. sauberer Stahl, Textil, Reifengummi mit einer Rein­ heit/Sauberkeit von bis zu 99,999%) bis zu einer Korngröße (kleiner) < 50 µm getrennt.Using cold - cooling the tires or the rubber -, up to -169.9 ° C and / or. (greater) <-180 ° C (e.g. through nitrogen) in tires and Materials contained in rubber due to additional external influences (e.g. grinding, impact) into their individual components le (e.g. clean steel, textile, tire rubber with a clean cleanliness of up to 99.999%) up to a grain size (smaller) <50 µm separated.

(larger) <-180 ° C, up to a grain size (smaller) <50 µm he follows.

Beispiel eines Ablaufes - Kaltrecyclingverfahren für ReifenExample of a process - cold recycling process for tires Vorzerkleinerungprecomminution

Große Reifen werden mittels einer Vorzerkleinerungseinrichtung in eine für den Shredder akzeptable Größe zerkleinert.Large tires are shredded using a pre-shredder shredded a size acceptable for the shredder.

ShredderShredder

Die Reifen werden mit dem Shredder in eine für die Kühlanlage wirt­ schaftliche Größe geshreddert und in Silos zwischengelagert.The tires are shredded into a cooling system shredded and temporarily stored in silos.

Kühlung (z. B. Stickstoff)Cooling (e.g. nitrogen)

Aus den Silos werden die Shredd's in die Kühltunnels transportiert und kommen nach der Abkühlung in die Granulatmühle. The shredds are transported from the silos to the cooling tunnels and come into the granulate mill after cooling.  

Granulatmühle (z. B. Kühlung mit Stickstoff)Granule mill (e.g. cooling with nitrogen)

Nach der Vermahlung wird die Trennung (z. B. Gummi, Stahl, Textil) vorgenommen.After grinding, the separation (e.g. rubber, steel, textile) performed.
