Trough Screw Conveyor

Trough Screw Conveyors: Accessible and Versatile Bulk Handling

 

The Trough Screw Conveyor (U-Shape) is designed for applications where ease of access and maintenance are priorities. Featuring a removable top cover, this conveyor allows for frequent cleaning and inspection, making it ideal for industries like food processing, grain handling, and chemicals.

 

Its U-shaped housing is perfect for horizontal or slightly inclined transport, and it excels in systems requiring multiple inlet and outlet points for controlled material distribution.

 

Key Advantages:

  • Easy Maintenance: Quick-access covers for rapid cleaning and screw inspection.
  • Flexible Loading: Easily integrated with multiple inlets and discharge gates.
  • Standardized Design: Built to LS/GX industrial standards for high reliability.

Frequently Asked Questions

 

Q: Do you provide OEM service?

A: Yes. Any required logos is available.

Q: What certificates do you have?

A: CE/ISO/SGS

Q: Do you offer after-sales service?

A: Yes. Engineers available.

Q: How long is your warranty?

A: One year after the arrival of the goods. During this period, as long as it is not a man-made damage, we send the damaged parts free of charge.

Q: What about your delivery time?

A: Normally within 45 days against down payment.

Q: How do I choose between a Tubular and a Trough screw conveyor?

A: Use Tubular for total dust containment or when conveying at angles above 20°. Use Trough (U-shape) for horizontal transport where easy cleaning or multiple inlet/discharge points are required.

Q: What is the maximum inclination for a screw conveyor?

A: While 15-20° is standard, our specially designed Tubular systems can handle up to 90° (Vertical Screw Conveyors) with high-speed rotation and optimized pitch.

Q: Do you offer replacement Screw Flights?

A: Yes, we provide custom Screw Flights and continuous helicoid augers for maintenance and repair of existing systems.
