ABSTRACT:
Automobile tires and analogous articles of rubber or synthetic plastic material are frozen to make them brittle, and thereupon are fragmented in order to separate their rubber or synthetic plastic material from embedded reinforcements of textile or analogous fabrics. The fragmenting is carried out by dropping the articles into an impact mill in which a rotor equipped with striking elements turns about a horizontal axis, so that the articles are hit by the striking elements of the rotor and flung in circumferential direction of movement of the rotor against impact plates from which they drop back onto the rotor, whereby the articles are fragmented by the repeated hits and impacting. An apparatus for carrying out the method is also disclosed.
