Chain Scraper Conveyor Working Principle
The chain scraper conveyor transports bulk materials through a sealed trough using circulating chains with attached flights. Driven by a motor, the head sprocket pulls dual strands of chains, causing the welded flights to push materials along the trough via positive displacement. As the material layer is agitated by the flights, internal pressure and friction are generated. When this force exceeds the friction between the material and trough walls, the bulk material flows in a fluidized state (mass-flow principle) at a speed nearly matching the chain velocity (0.1-0.5 m/s).
This system excels in three-dimensional conveying and dust containment. Specially designed flight angles (typically 45°-60°) and trough profiles enable horizontal, inclined (≤45°), and vertical configurations. The fully enclosed trough with wear-resistant linings ensures minimal dust leakage. Unlike conventional chain conveyors that rely solely on frictional drag, the scraper mechanism forcibly propels materials, making it ideal for powders and granular materials with poor flowability (e.g., cement, coal powder, grains). Energy consumption is 30%-50% lower than screw conveyors for equivalent capacity.

| Characteristics | Description |
| Large carrying capacity | A scraper conveyor has the advantages of small size and large conveying capacity. It only needs 1/5 of the space of the belt conveyor or 2/3 of the space of the screw conveyor to transport the same flow of materials. Conveying capacity is 6m3/h~500m3/h. |
| Long service life & low cost | The scraper conveyor chain made of alloy steel by scientific heat treatment processing has a normal life of more than 5 years. And the life of the roller on the chain is not less than 1 year (the most vulnerable part of the whole machine). This ensures that the annual maintenance is less than once, which greatly reduces the use cost and improves the production efficiency. |
| Low energy consumption | The chain conveyor uses the internal friction of the material to convert most of the work done by the moving parts into effective work. The use of chain hook transportation greatly reduces the resistance of the material to it, so that its energy consumption is only 30% to 60% of the screw conveyor. |
| Sealed and secure | The whole scarper machine is fully sealed, making the dust seamless drilling, waterproof and rainproof, easy to operate, safe and reliable operation. |
| Flexible process | The chain machine allows a variety of types of inlet and outlet at any location in the casing. It can be elevated, ground or pit arrangement and can be mounted horizontally or uphill (≤15°). |
