What is a Scraper Flight?
A Scraper Flight (also referred to as a flight attachment) is a component mounted directly onto the chain links of a drag chain conveyor system. Its function is to scrape, push, or drag bulk materials—such as powder, granules, ash, and clinker—through enclosed conveying systems within manufacturing plants and production lines.
Typically, scraper flights are manufactured from materials such as engineering plastics (UHMW-PE, PA6, POM), technical rubber, or composites. This ensures mechanical strength, high abrasion resistance, and chemical resistance suitable for heavy industrial environments.
Plastic Scraper Flights are custom-machined and cut by Focus Engineering Co., Ltd. using high-quality imported plastics to meet specific customer requirements. We ensure a diverse range of sizes and materials, allowing for the optimal selection based on your specific working environment. These flights are essential attachments for drag chains and cable conveyors, designed to efficiently transport bulk materials and assist in cleaning the conveying path during operation.
Structure of Scraper Flights
The table below outlines the basic construction of scraper flights, including components such as: material, shape, dimensions, etc.
| Feature / Component | Detailed Description |
| Material | Engineering plastics (PA6, UHMW-PE, POM), composites, or technical rubber. |
| Shape | T-shaped, U-shaped, semi-circular, or curved depending on application requirements. |
| Mounting Holes | 2–4 drilled holes for securing with bolts or fixing pins to the chain links. |
| Dimensions | Compatible with chain standards such as C102B, C112, C142, C157, C205, etc. |
| Design Type | Typical models: BR-type (U-shaped), BF-type (flat-type), manufactured by Sanwei. |
Technical Specifications of Scraper Flights
Scraper flights possess fundamental characteristics such as hardness, operating temperature, and resistance to abrasion and chemicals. For detailed parameters regarding these properties, please refer to the information table below.
| Property | Typical Value |
| Material Hardness | 60–80 Shore D |
| Operating Temperature | -40°C to +90°C |
| Abrasion Resistance | Very High (especially with UHMW-PE or POM) |
| Chemical Resistance | Good resistance to mild acids, alkalis, and industrial oils |
| Weight / Density | 3–7 times lighter than metal, significantly reducing system load |
| Recyclability & Maintenance | Some types are recyclable or allow for easy modular replacement |
What are the Key Advantages of Scraper Flights?
Based on their specific characteristics and construction, Scraper Flights offer several outstanding benefits:
- High Abrasion Resistance: Materials like UHMW-PE and Nylon feature a low coefficient of friction, which significantly reduces wear and tear and extends service life.
- Lightweight: Reduces the load on the chain system and the drive motor (lowering energy consumption).
- Non-Sparking Safety: Safe for operation in explosive or hazardous environments containing combustible materials such as coal dust or cement dust.
- Easy Installation & Replacement: The modular design allows for quick maintenance or replacement simply by removing the bolts.
- Continuous Operation Capability: Optimized for bulk material handling lines running through long production shifts.
Industrial Applications of Scraper Flights
Scraper flights in chain conveyor and drag chain systems are widely applied across various industries due to their ability to efficiently transport bulk materials within enclosed environments.
In the Cement and Construction Materials industry, they are used to drag clinker and cement powder from silos or within horizontal conveying systems. The Thermal Power sector utilizes scraper flights to handle fly ash and bottom ash from boilers, ensuring a safe and clean working environment. In Animal Feed Production, these flights help move bran, cereal powders, and other powdery ingredients precisely and gently.
For the Chemical and Plastics industries, scraper flights are capable of transporting plastic pellets, urea, or mildly corrosive chemicals without compromising their lifespan or structural integrity. Additionally, in the Mining industry, they play a crucial role in transporting fine ores and limestone powder within mineral processing lines. Notably, waste treatment, peat, and sludge handling systems in the Environmental Industry also utilize flights to ensure continuous, airtight operation without causing secondary pollution.
In summary, the Scraper Flight is a small component that plays an essential role in drag chain systems. Selecting the correct flight (in terms of material, shape, size, and technical characteristics) contributes significantly to improving efficiency, optimizing operations, and extending the system’s lifespan.
