MELTING TECHNOLOGY
         Melting technology
               The ‘hot glass’ area is covered
             by suitably designed drop chutes
             and scraper conveyors, the “cold
             glass” area by conveyors, crush-
             ers, magnetic separators, etc.
             Thus, with this technology the
             prepared cullet can be fed back
             to the furnaces.
               Both furnaces are operated
             with a – for Asian conditions –
             high cullet ratio of min. 40 per-
             cent. The required foreign cullet
             is delivered prepared, but may
             still contain impurities.
               Apart from conventional metal
             detection, a fully automated all-
             metal-elimination process, by
             means of an eddy current sys-
             tem, is integrated into the cullet
             dosing system. Thus it is possi-
             ble to improve the quality of the
             dosed cullet and consequentially
             increase the furnace lifetimes.
               In order to specifically prevent
             the introduction of Fe/Ne met-
             als in the melt, a complex Fe/
             Ne separation system was inte-
             grated into the feeding process
             for storing the cullet in foreign
             cullet silos. Here, attention was
             not only paid to the detection
             and elimination of impurities, it
             was also ensured that as little as
             possible cullet is discarded and
             thus saving lost ‘precious raw
             materials’.
