An automotive windshield is comprised of two layers of glass and a plastic liner sandwiched in between The present invention strips the glass from both surfaces of the inner plastic liner, comminutes the glass and separates the two substances for recovery. A windshield is fed into the unit by means of dual horizontal feed rollers. The windshield then passes over a stationery breaker bar and into the path of a plurality of rotating flexible impactors. The force of the rotating impactors on the top surface and the stationery breaker bar on the under surface act together to strip the glass from both sides of the inner plastic liner material. The glass is hammered into small particles the size of gravel and sand while the plastic breaks into much larger fragments. A shaker screen located below the rotating impactors serves to separate the two substances for individual recovery. | |
