Highest product quality – easy lining technique
Transfer of the advantage of LC catables to dry gunning materials
Application of high resistant low cement gunning concrete
- Use of conventional dry gunning machines
- Could be applied by “standard“ personel
- High layer thickness in one process
- Dust reduction with REFKO gunning technology
- Low amount of water
- Low porosity, less infiltration
Comparison between Classic Gunning vs. Dense Gunning/SuperGun System
| Classic RC Dry gunning | Dense Gunning SUPERGUN |
|
|---|---|---|
| Raw material | Bauxite ( appr. 7% CaO ) | Bauxite (appr. 2% CaO ) |
| CCS ( 110°) in MPa | 60-70 | 30-50 |
| CCS ( 1000°C ) in MPa | 35-45 | 60-80 |
| CCS ( 1500°C ) in MPa | 30-40 | 70-90 |
| Bulk density , g/cm³ | 2,5 | 2,7 |
| Porosity, % | 26 | < 22 |
| Abrassion resistance ASTM, 815°C | 24 ccm | < 10 ccm |
| Rebound losses | 20-25 % | 10-15 % |
Equipment for SuperGun System:
| Dry gunning machine
Characteristics: Air: min. 7 bar min. 10 m³ / min ! All possible air-connection at the gunnig machine must be connected to the air supply !
Output: approx. 3 – 4 t / h ( depending on the rotor) |
| HPM / REFKO Gunning Nozzle
Characteristics: water pressure: approx. 15 – 20 bar
lightweight flexible dust reduction |
Application SuperGun System
Cooler/Kiln Hood – Cement Plant
Riser duct - Cement Plant
