FB-DRWF series double-layer rotor can realize the effect of physical accumulation and sealing of powder, and locking the pulverized material and gas totally. It solved the material blanking problem when using the single-layer rotor to measure powder.
1. It is double layer rotor curved path stepped labyrinth structure, so the material and air is locked well, also avoid material flushing;
2. Large measurement area, measurement accuracy ±0.5%；
3. The feeder body is sealed as a whole, environment-friendly and can avoid flying dust effectively;
4. Long term stability of zero point;
5. The feeder is simple and can be calibrated by hanging weights;
6. The installation space is not limited.
