Product Description

The U-shaped scraper conveyor chain is a high-strength traction chain specially designed for U-trough scraper conveyors, primarily used for horizontal or slightly inclined transportation of powdered, granular, and small lump materials (such as grain, coal, cement, fertilizer, etc.). Typically made of high-quality alloy steel, this chain offers excellent wear resistance, tensile strength, and corrosion resistance, ensuring stable operation even in harsh working conditions.

Main Structural Components

  1. Chain Links: Manufactured through forging or stamping processes, ensuring robust structure and high load-bearing capacity.

  2. Chain Plates: Usually designed in an "8"-shaped or straight-plate configuration to enhance tensile strength.

  3. Pins and Bushings: Hardened to reduce friction and improve wear resistance.

  4. Scraper Attachments: Fixed onto the chain to push materials forward, available in materials such as carbon steel, stainless steel, or wear-resistant alloy.

  5. Connection Method: Features detachable or welded structures for easy installation and maintenance.



Key Features

  1. High Strength & Wear Resistance: Made of premium alloy steel (e.g., 40Cr, 40Mn) or surface-hardened for extended service life.

  2. Strong Impact Resistance: Suitable for high-load, continuous operation without deformation or breakage.

  3. Corrosion-Resistant Design: Options include galvanizing, blackening, or coating for use in humid or corrosive environments.

  4. Smooth Operation: Precision machining ensures seamless engagement with sprockets, minimizing noise and vibration.

  5. Easy Maintenance: Modular design allows individual chain link replacement, reducing maintenance costs.

  6. High Adaptability: Customizable pitch (e.g., 60mm, 80mm, 100mm) to match conveyor trough width and load requirements.



Applications

U-shaped scraper conveyor chains are widely used in the following industries:

  1. Grain Processing: Transporting wheat, corn, soybeans, and other granular materials.


  2. Coal & Mining: Conveying coal, ores, and minerals in underground or surface operations.


  3. Building Materials: Handling cement, sand, fly ash, and other construction materials.


  4. Chemical Industry: Moving fertilizers, plastic pellets, and other mildly corrosive chemical products.


  5. Renewable Energy: Transporting biomass fuels like straw and wood chips in power plants.


Compatible Equipment: U-shaped scraper conveyors, enclosed scraper conveyors, trough conveyors, etc.

This chain excels in continuous, heavy-duty, dusty, or humid environments, making it a core component of bulk material handling systems.
