Cullet silos in scrap glass recycling
Glass is manufactured from quartz sand, lime and soda at temperatures up to +1600 °C. The melting process is very energy intensive, so easily melting waste glass is often added to the melt in certain proportions. After being delivered, the waste glass is first crushed and conta-minants are sorted out. Then the material is transported to the cullet silos and fed into the melting process from there. To ensure a continuous supply of material for the melting furnace, a reliable level measurement is required in the cullet silos.
Level measurement with VEGAPULS 67
The radar sensor VEGAPULS 67 is the optimal solution for level measurement in the cullet silo due to the noise and dust during the filling process as well as the abrasive, sharp-edged glass fragments. Specially developed for bulk solids with unfavourable reflective properties, it measures contactlessly and entirely without wear. For larger silos over 15 m high, the radar sensor VEGAPULS 68 is used.
Backup detection with VEGAMIP 61
The microwave barrier VEGAMIP 61 serves as a backup detection device. It consists of a transmitter and a receiver and is mounted on the side of the feed shaft. A ceramic adapter makes the microwave barrier completely resistant against the abrasive waste glass.
