Custom Twin-Screw Helical Assembly

Product Overview

Jiahe Conveying's Custom Twin-Screw Helical Assembly is a precision-engineered conveying solution featuring intermeshing dual screws for specialized industrial applications. Our bespoke twin-helix design delivers superior material processing through controlled mixing, conveying, and compression in a single integrated system.

Technical Specifications

Design Features

1. Precision Twin-Screw Geometry

• Matched helix engagement (0.9-1.1 × screw clearance)

• Phase-synchronized flights for uniform processing

• Custom compression ratios (1:1 to 5:1)

2. Advanced Material Options

• Tool steel (HRC 45-60) for abrasive applications

• Corrosion-resistant alloys (Hastelloy, Duplex)

• Surface enhancements (HVOF, PVD coatings)

3. Process-Specific Elements

• Kneading/mixing sections (30°/60°/90°)

• Reverse pitch elements for back-pressure

• Venting/stripping zones

• Barrier flight designs

Performance Advantages

• 300% better mixing homogeneity vs single screws
