VIBROTUBE®´s 1-year results “stunning”

ZIPPE´s new VIBROTUBE® batch charger has been in operation for more than 1 year now at a state-of the art container glass production facility with approx. 300 tpd in Germany, where it started in May 2014.  Time enough to make a short resume about the energetic results.

The new and innovative concept´s inherent characteristics are a complete sealing of the doghouse in comparison to existing chargers on the market, less wear, an improved batch distribution in the melting bath and better adjustment possibilities.

The following graphs show the changes in temperatures and energy consumptions before the exchange of the machines (2 standard chargers “tray feeder-pusher type”) and after (2 VIBROTUBE®).

(All other factors were kept constant; data reflect official operators´ protocol)

  standard VIBROTUBE®  
Daily tonnage 271,4 288,8 t/24h
Temperature vault 1608 1586 °C
Temperature furnace bottom 1143 1171 °C
Specific heat 912 856 kcal/kg
Specific melting rate 3,19 3,4 t/m²d
Amount of gas ca. 1.400 ca. 1.400 Nm³/H

“The results are stunning and have clearly outperformed our expectations. It was evident that we would expect improvements, but the magnitude of the energy savings due to the VIBROTUBE® was not predictable. For us these results and the high satisfaction of the customer show that we are on the right track with the VIBROTUBE®”, say company officials.
