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
