ABSTRACT:
A process and apparatus are provided for breaking the glass components of articles comprised of glass and nonglass components and liberating the glass components from the nonglass components by subjecting the articles to controlled vibrations sufficient to break the glass without breaking the nonglass components. The apparatus is a vibratory device having a screen deck and a plate deck. The screen deck has holes through which the broken glass falls to the plate deck. The nonglass components remain on the screen deck. Thereafter, the nonglass components are removed by one or more of a variety of means. The glass may be further processed by cleaning, rinsing and further crushing to size the glass pieces. Glass of different types may optionally be separated by taking advantage of the differences in specific gravities between glass types.
