The $480K/Year Clogging Crisis in Industrial Dewatering
Petrochemical, food processing, and pulp/paper plants face chronic screw press failures:
- Fiber wrapping: 80% downtime in textile wastewater plants
- Inorganic abrasion: Screw wear rate triples with >10% silica content
- Oil-induced slippage: 40% torque loss in lubricant manufacturing sludge
JUNTAI's dual-shaft compression technology solves these through mechanical synergy:

Dual-Screw Synergy: 3 Engineering Breakthroughs
1. Counter-Rotating Force Field
- Helical Phase Angle: 22° offset creates shear planes disrupting fiber entanglement
- Torque Amplification: 2,500 N·m combined torque (vs 1,200 N·m in single-screw)
- Case: Guangdong dyeing mill eliminated weekly unclogging operations
2. Asymmetric Pitch Optimization
| Section | Feed Zone Pitch | Compression Zone Pitch |
|---|---|---|
| Single-Screw | 300 mm | 120 mm |
| JUNTAI Dual | 420 mm → 180 mm | 150 mm → 80 mm |
- Mechanism: Progressive pitch reduction + diameter expansion boosts solids retention time by 70%
3. Anti-Wear Plasma Cladding
- Surface Hardness: HV 1,200 (3X standard SS316)
- Abrasion Resistance: 15-year lifespan in cement plant sludge with 25% ash content
Performance Data: Oil Refinery Sludge Treatment
| Parameter | Single-Screw Press | JUNTAI Dual-Screw |
|---|---|---|
| Cake Dryness | 68% | 78% (+10%) |
| Fiber Clogging | 3/week | 0 (100% resolved) |
| Energy Use | 0.8 kW·h/m³ | 0.5 kW·h/m³ (-37%) |
Client Testimonial:
"The dual shafts shredded palm oil fibers like scissors – no more manual cleaning!"
