Wear Resistant Drag Chain for Bulk Material

Product Description

Our Scraper Chains, also known as Drag Chains, are designed for continuous conveying of bulk materials in enclosed or semi-enclosed conveyor systems. With a robust structure and excellent wear resistance, they ensure stable and efficient material transportation under heavy-duty working conditions.

Key Features & Benefits

1.Strong Scraper Structure

• Equipped with wear-resistant scrapers firmly attached to high-strength chains, providing reliable material pushing and conveying performance.

2.High Load Capacity

• Manufactured from high-quality carbon steel or alloy steel, capable of handling heavy loads and high impact forces.

3.Excellent Wear & Abrasion Resistance

• Heat-treated chains, pins, and scrapers ensure long service life even when conveying abrasive materials.

4.Stable & Continuous Operation

• Designed for smooth movement with precise pitch control, reducing vibration and operational noise.

5.Adapted to Harsh Environments

• Performs reliably in dusty, high-temperature, or abrasive working conditions.

Scope of Application

• Scraper Chains are essential across various heavy industries dealing with bulk solids:
• Power Generation: Handling fly ash, bottom ash, and coal/biomass feeding.
• Cement Industry: Conveying clinker, limestone, and cement powder.
• Grain and Agriculture: Moving grain, feed, and seeds within silos and processing facilities.
• Mining and Quarrying: Transporting excavated material, ores, and aggregates.
• Waste Incineration: Moving incinerated ash and residuals.

Close cooperation with factories

We maintain deep, long-term partnerships with the factory around 20 years. The factory has strong mechanical and automated production capabilities which ensure stable quality and performance of the products.

Quality control

The factory's rigorous quality control process includes material spectroscopy analysis, in-process inspections, and final checks with Magnetic Particle Testing (MPT) to ensure every bucket is free from defects and meets our high standards. The details controll process as below,

1. Incoming raw materials undergo random sampling and analysis using a microscope to ensure the chemical composition meets production requirements.

2. During the production process, QC staff conduct timely sampling to ensure products are defect-free and handle any abnormal quality issues that may arise.

3. The final step involves using a magnetic particle flaw detector on metal parts to detect hidden cracks or defects.

4. All finished metal parts are proportionally sampled and sent to the laboratory for mechanical performance tests, size measurement, and 100% manual surface quality inspection.

Why Choose Scraper Chains?

Scraper Chains are favored in bulk material handling for their efficiency and resilience:

• High Bulk Throughput: Capable of moving large volumes of material efficiently over long distances, often within a compact profile.
• Dust and Leak Prevention: Since the system is fully enclosed (trough design), it prevents dust emission into the environment and protects the conveyed material from external contamination.
• Versatile Path Options: Can effectively convey materials along horizontal, inclined, and even vertical paths (especially for deep-pan or bucket elevator variations).
• Robust Abrasion Resistance: The underlying chains are specifically designed to withstand the abrasive nature of bulk solids like coal, ash, cement, and grains, ensuring long service life.
• Temperature Resilience: When constructed from heat-resistant alloys (often cast steel), they can handle hot materials such as boiler ash or clinker.
