METHOD OF PRODUCTION OF RAW MATERIAL CONCENTRATE FOR MANUFACTURE OF GLASS

摘要

FIELD: glass industry; raw materials used for production of glass. ^ SUBSTANCE: raw material concentrate contains finely-dispersed natural marshalite instead of quartz sand. Proposed method includes preparation of marshalite, metering, mixing with water at ratio of (70-80) : (20-30), respectively and compacting with the aid of roller press. Strength of compacted grit is 1.6-1.8 Mpa at size lesser than 0.5 mm. Glass making time is reduced by 15-18%. ^ EFFECT: extended range of raw material sources; enhanced homogeneity and chemical activity of glass charge. ^ 2 ex
