WLS-260
BOEEP
WLS
The BOEEP shaftless screw conveyor is a high-performance heavy-duty conveying equipment specially engineered for industrial and wastewater treatment applications. Distinguished by its innovative center-shaft-free design, this conveyor eliminates the interference of a central axis, making it perfectly suitable for conveying winding materials, grid residues removed from sewage screening equipment, and dewatered sludge cakes. Its working principle relies on the rotation of a helical body inside a U-shaped trough, realizing stable and efficient material transportation for industrial purchasers and engineering contractors.
This industrial shaftless screw conveyor integrates multiple practical benefits, fully meeting the strict requirements of engineering projects and large-scale material handling operations:
No central shaft structure effectively avoids material jamming and keeps the discharge port unobstructed, supporting low-speed operation and stable conveying.
Fully enclosed structure and easy-to-clean spiral surface prevent material leakage and secondary pollution, ensuring a clean working environment.
High torque output matched with low rotating speed greatly reduces energy consumption, achieving long-term cost reduction for industrial clients.
Manufactured in strict accordance with JB/T679-95 standard, it has high reliability, long service life, and can withstand materials up to 100℃.
Supports installation inclination up to 30°, adapting to various on-site layout requirements of wastewater treatment projects.
Compact structure with expansion bolt installation; wear-resistant trough lining simplifies daily maintenance and reduces downtime.
The shaftless screw conveyor is a robust integrated system composed of high-quality components, with customizable materials to fit different working conditions:
Driving Device: Equipped with helical gear reducer, arranged opposite the discharge port in horizontal installation and at the discharge port in inclined installation.
Main Body: U-shaped trough with rainproof cover, available in stainless steel or carbon steel.
Shaftless Screw Body: Made of stainless steel or 16Mn, corrosion-resistant and high-strength.
Trough Lining: Nylon or polyethylene plate, wear-resistant and low-friction.
Inlet & Outlet: Two types (square × round), square type is the standard configuration and customizable per client requirements.
Auxiliary Parts: Including base, support feet and optional protective cover for full-scene adaptation.
