    摘要: Process for recovery of glass from municipal waste, comprising shredding the waste, subjecting the shredded waste containing the glass to treatment in an air classifier, recovering the overhead including glass from the air classifier, the latter being operated under conditions such that the major portion of the glass particles contained in such overhead are of a fineness smaller than about 6 mesh, and usually of a size such that a substantial portion of such glass particles are less than about 20 mesh, screening such overhead fraction and recovering an enriched glass fraction of the aforementioned fineness, subjecting the screened glass-enriched material to treatment on an air table, and recovering a fine glass product of substantially reduced organic content, and having a particle size less than about 6 mesh, with a substantial portion less than about 20 mesh. Such fine glass product containing a substantial portion of glass particles of a size less than 20 mesh, can be employed in construction applications, e.g. in admixture with asphalt to form slurry seal, for production of glass and resin binder sheets, and the like, and may be further beneficiated to sufficient purity for recycle to glass manufacture.
