Case Study: Special Rubber Conveying Solution
? Client Background & Challenge
Client: [請填寫客戶名稱，如：A leading specialty rubber compounds manufacturer in Southeast Asia]
Industry: Rubber & Polymer Processing
Challenge: The client needed to convey special rubber pellets and rubber powder blends from mixing area to processing lines. The material presented unique difficulties: high adhesion, tendency to agglomerate under pressure, temperature sensitivity, and irregular particle shapes causing blockages in standard pneumatic systems. Existing mechanical conveyors caused material degradation and required frequent cleaning due to residue build-up, leading to production downtime and cross-contamination risks.
✅ Guanjiang's Custom Solution
After analyzing the material characteristics and process requirements, Guanjiang provided a customized dilute-phase positive pressure pneumatic conveying system with the following key features:
- ? Special Non-Stick Inner Surface: Conveying pipes and receivers lined with ultra-smooth PTFE coating to prevent rubber adhesion and build-up.
- ? Low-Velocity Gentle Conveying: Designed lower air velocity (8-12 m/s) to prevent degradation of soft rubber pellets while maintaining suspension flow.
- ? Temperature Control Jacket: Cooling air jacket on the receiver to dissipate frictional heat, keeping rubber temperature below 40°C.
- ? Anti-Clogging Rotary Valve: Special rotor design with adjustable clearances to handle irregular rubber particles without jamming.
- ? Fully Enclosed Dust-Free System: Prevents fine rubber dust emissions and protects operator health.
- ? PLC Automated Control: Integrated with client's DCS for batch tracking, flow monitoring, and automatic purge cycles.

? Implementation & Results
| Parameter | Before (Manual/Mechanical) | After (Guanjiang System) | Improvement |
|---|---|---|---|
| Conveying Capacity | [如: 1.5 T/h] | [如: 3.2 T/h] | +113% |
| Material Degradation Rate | [如: 5.2% fines generated] | [如: 0.8% fines generated] | -85% |
| Cleaning Frequency | [如: Daily (2 hours)] | [如: Weekly (30 minutes)] | -75% downtime |
| Dust Exposure Risk | High (open system) | Eliminated (enclosed) | 100% reduction |
| Production Uptime | [如: 72%] | [如: 94%] | +22% |
⭐ Key Outcome: The Guanjiang system successfully conveyed [如: 15,000 tons] of special rubber compounds in the first year with zero unplanned downtime and no material contamination incidents. The client achieved rapid ROI within [如: 8 months].
? Client Testimonial
“Guanjiang's engineering team understood our rubber conveying challenges from day one. Their PTFE-lined system completely solved our adhesion and clogging problems. Production efficiency has increased significantly, and the automated CIP feature saves us hours of manual cleaning every week. We are now planning to replicate this solution in our other plants.”
