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.
