Accessibility and High Capacity
The Trough Shaftless Screw Conveyor features a U-shaped housing with removable top covers, providing unmatched accessibility for maintenance and internal cleaning. This open architecture is ideal for processing plants where frequent inspections are required to ensure the continuous flow of irregular or sticky bulk solids.

Customizable Discharge and Liners
Our trough design supports multiple inlet and outlet points, allowing for flexible material distribution. To extend service life, the trough is fitted with ultra-high molecular weight (UHMW) polyethylene liners, which provide a low-friction surface and protect the casing from wear caused by the shaftless spiral.

Features
1. It has super abrasion resistance and durability, and has a long service life.
2. Large torque and low energy consumption: due to the use of shaftless, the material is not easy to be blocked, and the discharge port is not blocked, so it can run at a lower speed and drive smoothly to reduce energy consumption.
3. The conveying capacity is large and the distance is long. The conveying capacity is 1.5 times that of the spiral of the same diameter, and the conveying distance can reach more than ten meters. It adopts multi-stage series installation according to customer needs.
4. The inner wall of the shell adopts a special liner, which can work under high temperature, and can use different material liners according to the characteristics of the conveying materials.
5. Strong anti-winding performance: It adopts no central axis and no hanging device, which has special advantages for conveying belt-shaped and easy-winding materials, and prevents mechanical failures caused by blockages in the conveying process.

Industrial Applications
The premier choice for household waste recycling, food processing scrap, and large-scale agricultural distribution.
FAQ
Q: How often should the UHMW-PE liners be replaced?
A: Liner life depends on the abrasiveness of the material. However, our U-trough design features bolted covers that allow for a full liner inspection in minutes, ensuring you can plan maintenance before any metal-to-metal contact occurs.
Q: Can the trough handle large, irregular objects?
A: Yes. Because there is no central shaft, large or "stringy" objects (like household waste or industrial rags) can pass through the trough without wrapping around a center pipe, which is a common failure point in standard conveyors.
Q: Is it possible to have multiple inlet points on a trough conveyor?
A: Absolutely. The flat-top trough design is ideal for multiple loading zones, allowing you to collect waste from several processing machines simultaneously.
