A granulator for separating the constituent parts of electrical cable containing relatively light-weight plastic covering relatively heavy electrically-conductive material. The granulator includes a first cutter for cutting the cable into short pieces and a second cutter for cutting the short pieces of cable into a still shorter length sufficient to detach the plastic from the electrically-conductive material to form a mixture of small pieces of plastic and electrically-conductive material. A vibratory sorter separates the mixture of plastic and electrically-conductive material, and includes an elongate, circular and spirally-extending track having a material inlet adjacent a bottom end thereof for receiving the mixture of plastic and electrically-conductive material for separation and a electrically-conductive material discharge slot adjacent a top end thereof for discharging electrically-conductive material. A vibrator impart vibratory motion to the mixture of plastic and electrically-conductive material sufficient to cause the mixture to move upwardly along the track and to vertically separate into a relatively heavy bottom layer of electrically conductive material and a top layer of relatively light-weight plastic pieces riding on top of the layer of electrically-conductive material. A plurality of vertically spaced-apart air jets apply respective radially-extending air blasts to the top layer of plastic pieces as the plastic pieces vibrate progressively up the track on top of the electrically-conductive material. The air blasts have sufficient energy to blow the plastic pieces off of the track but insufficient energy to blow the electrically-conductive material off of the track.
