  • Patent number: 4867384
    Abstract: Method and apparatus for recovering glass from old glass by continuously feeding the old glass onto an open, continuously running conveyor system by segregating nonglass impurities and by mechanically crushing old glass in a breaking apparatus. To facilitate visual inspection and concentrating the size range of the shards, a sorting of the old glass into two fractions of different piece sizes is performed in a separating apparatus prior to the manual sorting and before crushing. Exclusively the old glass of the at least one coarser fraction ("coarse glass") is fed, after the segregation of at least a portion of the nonglass impurities, to the breaking apparatus. Then the old glass of this fraction, crushed to the desired shard size, is freed of remaining impurities and finally fed to a place of storage for good glass.
