METHOD FOR PRODUCTION OF RAW MATERIALS BASED ON BROKEN GLASS OF KINESCOPE MANUFACTURE Russian patent published in 1998 - IPC

FIELD: processing of industrial wastes, in particular, wastes of kinescope manufacture; may be used in production of secondary raw materials based on broken glass used in manufacture of various industrial products. SUBSTANCE: method includes crushing of broken glass to sizes of 150x150-70x70 mm, grading of broken glass into cone, shield and mixed broken glass, separate grinding of cone and shield broken glass to fractions within 40 mm with subsequent rough cleaning from metal inclusions, separate mechanical working of broken glass in ball mills for 1.0-5.0 h with use of auxiliary materials in the form of nepheline-syenite and water, subsequent rough washing with vibration separation of granules of regenerated broken glass, cleaning from metal inclusions and finished washing of granules. Intermediate washing is accomplished with circulating water, and finishing washing, with service water. Mixed broken glass not yielding to grading is used in manufacture of building materials and articles, and regenerated broken glass is returned to manufacture of kinescopes. EFFECT: higher efficiency. 3 cl
