Introduction to Double Row Conveyor Chains for Bucket Elevators:

Double row conveyor chains are engineered for heavy-duty applications in bucket elevators, where high load-bearing capacity and stability are required. These chains facilitate the movement of materials through the conveyor system. Here is a brief introduction:

1. Functionality: Double row conveyor chains consist of two parallel rows of links that support the buckets, allowing for the transportation of bulk materials in a continuous and efficient manner. They are designed to handle high dynamic loads and provide a robust means of support for the buckets, which is crucial for the efficient movement of materials.

2. Design and Construction: These chains often feature separate angular brackets for bucket fixation, fitted loosely to elongated chain bolts to absorb vibrations and increase fatigue resistance of the buckets. The chains are manufactured with high-precision processes and reliable material sources to ensure a long service life.

3. Material and Heat Treatment: Double row conveyor chains are made from high-quality European steel grades. The bolts are tempered, quenched, and finally inductively hardened. High wear resistance is achieved by sufficiently deep hardening depths of case-hardened bushes as well as inductively hardened tempered and quenched bolts. The flat link plates are made of high-quality, heat-treated fine-grained steel.

4. Applications: Double row conveyor chains are used in a variety of industries, including cement, mining, agriculture, and chemical processing, where they are employed to transport bulk materials such as limestone, aggregates, clinker, slag, cement, gypsum, coal, ores, and fly ash.

5. Advantages:

   • They offer high fatigue strength while maintaining excellent wear resistance and optimum service life.
   • The chains can be designed to meet individual customer demands, with a wide range of dimensions and assemblies available.
   • For higher loads, chains with forged links made from boron-alloyed quenched and tempered steel are provided, offering increased support width and reduced surface pressure.

6. Maintenance: Regular maintenance is essential for double row conveyor chains to ensure their longevity and prevent system failures. This includes checking for wear, ensuring proper lubrication, and replacing chains or components that show signs of excessive wear or damage.

In summary, double row conveyor chains are a vital part of bucket elevator systems, providing a reliable and durable means of material transport in various industrial applications. Their design, construction, and proper maintenance are critical for the efficient operation and longevity of the elevator system.
