ABSTRACT:
The present invention relates to a method for disintegration of thermoplastic elastomeric materials containing fibres, wires or the like. This method comprises the following two steps: subjecting segments of the elastomeric materials to temperatures able to bring the segments into a brittle glass-like state (by means of a freezing chamber), and gradual disintegrating of the frozen segments by disintegrating means provided to separate the segments from the wires and fibres. This disintegration is effected by means of a bending force applied to the frozen segments causing them to break into small particles while the wires and fibres remain substantially intact. After the disintegration, separation of the small particles, wires and fibres takes place by separating means. The disintegrating means comprises a roll means, where the roll means is provided with mating bending surfaces spaced apart from each other at predetermined distances and facilitating maximum bending and breaking of the frozen segments being advanced between the roll means. The roll means may comprise two sets of rolls, where distance between the first set of rolls is bigger than the distance between the second set of rolls to facilitate gradual breaking of the frozen segments. The mating bending surfaces are a plurality of semi-spherical heads, where the heads are spaced from each other in such a way that heads on the mating surface of one roll are mating with a space between heads on the mating surface of another roll.
