ERTONG MAKE

Overview The Bearing-Free Twin-Screw Conveyor is a breakthrough solution for handling highly adhesive, viscous, or semi-solid materials. By eliminating intermediate hanger bearings and utilizing dual intermeshing screws, this system prevents material buildup while ensuring smooth, clog-free transport. Designed for industries like food processing, chemical manufacturing, and wastewater treatment, it combines GB/T-compliant reliability with unmatched performance in sticky material applications. Key Features

1. Dual Screw Anti-Clogging Design
   • Intermeshing screws create self-cleaning action, reducing material adhesion by 90% vs. single-screw systems.
   • Torque capacity up to 8,000 N·m for high-viscosity substances (e.g., tar, grease, sludge).
2. Extended Unsupported Span
   • Operates up to 25 meters without intermediate bearings (modular extensions to 80 meters).
   • ±1° alignment tolerance prevents screw jamming under heavy loads.
3. Hygienic & Corrosion-Resistant
   • Full stainless steel construction (SS304/316L) with electropolished surfaces (Ra ≤0.8 μm).
   • CIP/SIP compatibility for food/pharmaceutical applications.
