Control Cage Function
Control cage is installed outside impeller wheel, controlling shot direction and fan angle from blades.
Core Functions
- Define shot blasting fan angle
- Control shot coverage area
- Work with impeller to distribute shots
Fan Angle Selection
| Fan Angle | Coverage Width | Application |
|---|---|---|
| 45° | Narrow | Small parts, spot treatment |
| 60° | Standard | General use, regular treatment |
| 90° | Wide | Large parts, quick coverage |
Angle Adjustment Method
Adjustment Steps
Stop Preparation
- Power off, ensure equipment stopped
- Clean area around control cage
- Prepare adjustment tools
Loosen Fixation
- Loosen control cage fixing bolts
- Do not remove bolts completely
- Keep control cage rotatable
Angle Adjustment
- Rotate control cage to target angle
- Observe control cage window position
- Confirm fan angle direction
Tighten Confirm
- Tighten fixing bolts
- Check tightening force
- Record adjusted angle
Adjustment Verification
Test Run Check
- Low speed observation of shot blasting
- Confirm shots cover target area
- Check for shot leakage
Effect Evaluation
- Workpiece surface treatment uniformity
- Processing efficiency meets standard
- Equipment runs stable
Common Issues
Shot Leakage
Cause: Excessive clearance between cage and impeller
Solution: Replace worn parts or adjust clearance
Uneven Coverage
Cause: Improper angle setting
Solution: Re-adjust control cage angle
Low Efficiency
Cause: Control cage window worn
Solution: Replace worn control cage
Maintenance Tips
Regular Check
- Monthly control cage wear inspection
- Confirm angle fixation status
- Check window shape integrity
Replacement Standards
- Window wear deformation
- Excessive fit clearance with impeller
- Mounting hole wear loose
Procurement Tip: We offer various fan angle control cages, 60° standard configuration, customizable 45°-90°.
