Low temperature size reduction of tires for recycling and recovery of cord materials, cools, size-reduces and grinds mixed tire and rubber feedstock

摘要

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.
