Description: Core rotating component for dust‑removal induced‑draft fans. Assembled via welding of hub, blades and back‑plate, and fitted to the fan main shaft. During high‑speed rotation it imparts momentum to process airflow, generating negative pressure for corn dust‑removal systems, drawing dust‑laden workshop gas and stabilizing airflow throughout full dust‑removal piping. It is the core power‑generating spare‑part for dust‑removal circuits.
Motor drives the impeller for high‑speed rotation. Blades transfer energy to air and build pressure differential, producing negative pressure inside dust‑collecting piping to draw mixed corn‑dust and husk‑particle gas into the dust collector. After filtration‑purification, treated airflow is exhausted by the fan.
Backward‑curved centrifugal impellers are standard. Base material is normally mild carbon‑steel; wear‑resistant steel plate is selected for severe dust‑erosion operating conditions. Wear‑resistant coating can be applied subject to process requirements to withstand continuous corn‑debris and dust abrasion.
1. Excellent aerodynamic performance, large air volume and high operating efficiency to satisfy negative‑pressure requirements for grain‑dust removal.
2. Factory‑dynamic‑balanced; low‑vibration and stable high‑speed running.
3. Robust wear‑resistant construction tolerates persistent corn‑husk‑dust erosion.
4. Easy disassembly‑assembly for convenient maintenance and overhaul; blade dimensions can be adapted to match fan model specifications.
