<p>A method of disintegrating plastics and/or rubber material, such as the plastics and/or rubber casings of metal cores, for the purpose of recovering the metal from scrap cables for example. The material to be disintegrated is cooled to a temperature at which it becomes brittle. The embrittled material is then subjected in at least one station to mechanical oscillations which cause the material to disintegrate. The oscillations suitably have a frequency in excess of 30 Hz and an amplitude of about 2-3 mm. The oscillations can be imparted with the aid of a vibratory device with which the embrittled material is brought into contact.</p> |
