A drag scraper chain conveyor operates through the coordinated movement of the chain, drag flights, sprockets, and support nylon rollers.
It should be correctly tensioned to avoid any slippage or disruptions in the material flow. Additionally, the drive unit must be functioning correctly to provide the necessary power for the conveyor’s movement.
Components of the Drag Scraper Chain Conveyor
Drag Conveyor Chain
The chain is the main component that carries the material along the conveyor’s path. It consists of interconnected links that form a continuous loop.
YT Conveyor manufactures the GLF 81X series scraper chain, which can be equipped with flat flights.

In the video, it is our GLR chain: https://www.ytconveyor.com/product/glr-scraper-conveyor-chain/, this kind of chain will equip our arch-type plastic flight.
Drag Bar
Chain flights are attached to the chain and are responsible for conveying the material. They come in various designs and can be flat or round, depending on the application.
For longer drag bars, additional support can be added to improve rigidity and stability.
We previously used flat plate supports, but we have now changed to a round bar support design. Why do we change this? We will have another blog, please follow our blog.

Chain Flight
Flights are optional components that can be attached to the drag bars to help move material effectively, especially in inclined or vertical applications.
The flight in the video is round type. YT conveyor link: https://www.ytconveyor.com/product/br-arc-drag-conveyor-flight/
The flat flight link: https://www.ytconveyor.com/product/bf-flat-drag-conveyor-flight/
Commonly, the material is HDPE or UHMWPE.

Chain Sprocket
We can customize sprockets according to customer drawings, with different tooth counts and dimensions.
You can ask for our blank drawing to fill in the data.

Nylon Roller
From the video, you may find the roller under the chain.
When the chain is long, its own weight may cause it to sag between support points.. So we can use the nylon roller to support it.

It can also be customized.
