Product Overview: The Industrial Workhorse
LS screw trough conveyor is a type of mechanical conveyor system that is used to transport materials from one point to another. LS screw trough conveyor is composed of a rotating helical screw blade, also known as an auger, that is enclosed within a tube or trough. The auger is driven by an electric motor, which rotates the auger and moves the material along the trough.
"LS" stands for the industrial standard model. This is distinct from light-duty U-conveyors. It is built for Mining, Cement Plants, and Power Stations.
- Long Distance: While standard screws are 3-6m, the LS series can be linked up to 30m - 60m.
- Head & Tail Bearings: The bearings are mounted outside the trough to isolate them from dust and heat.
Critical Component: Intermediate Hanger Bearings
To span long distances, the screw shaft is segmented (usually 3m per section). They are supported by Hanger Bearings inside the trough.
- Bearing Selection (Expertise):
- Rolling Bearing (M1): For non-abrasive material (Grain, Lime). Needs grease.
- Sliding Bearing (M2): Made of Copper or Babbitt alloy. Good for wear resistance.
- Self-Lubricating (M3): Made of specialized synthetic material. For abrasive dust like cement or coal ash where grease attracts grit.

Drive Arrangements (C1 vs C2)
- C1 Method: Motor connects via Coupling. High reliability, less maintenance.
- C2 Method: Motor connects via Chain/Sprocket. Allows speed adjustment by changing sprocket ratio. Compact layout.
Advantage
The main advantage of LS screw trough conveyor is its ability to move materials in a continuous, uniform manner. This is due to the fact that the auger is constantly rotating, which ensures that the material is evenly distributed throughout the trough. Additionally, the auger is enclosed within the trough, which helps to keep the material contained and prevents it from spilling out.
LS screw trough conveyors are also relatively easy to install and maintain.
LS screw trough conveyors are also highly efficient, as they can move large amounts of material in a short amount of time.

Working Site
LS screw trough conveyor is used in a variety of industries, including coal ash, chemical, electric power , agricultural, and construction. LS screw trough conveyor is used to move materials such as coal, sand, gravel, saw dust and other bulk materials from one location to another.

Typical Applications
- Concrete Plants: Horizontal distribution of cement on top of bins.
- Mining: Moving coal fines or mineral powder.
- Wastewater: Transporting dewatered sludge (Shaftless option available).
FAQ
Q: How to maintain the hanger bearings?
A: This is the most critical maintenance point. Some hanger bearings have external grease pipes-pump grease weekly. For self-lubricating types, inspect wear every 6 months.
