Double Shaft Paddle Mixer
The Ottevanger double shaft paddle mixer delivers fast, precise mixing with low energy use. Twin shafts create a fluidised mixing zone, achieving full homogeneity in 30 to 60 seconds with minimal product damage. A large drop bottom discharge ensures residue free, dust tight operation, with sizes from 500 to 12,000 litres for powders and granulates, with optional liquid addition.
- Fast mixing cycle (30–60 seconds)
- High accuracy (1:100,000 / C.V. < 5%)
- Residue- and dust-free operation
