It explains working principle, core advantages including low breakage, energy saving and 3D layout, application industries such as food, pharmaceutical, chemical and lithium battery, selection guide and daily maintenance. As a high-efficiency alternative to traditional conveyors, it provides safe, clean and cost-effective solutions for modern industrial handling.
Tube Chain Conveyor, closed pipeline conveyor, dust-free chain conveyor for powder, granules, food, pharmaceutical, chemical, lithium battery applications.
In industries handling powders, granules, and small bulk materials, the Tube Chain Conveyor has emerged as a top-tier conveying solution for chemical, food, pharmaceutical, lithium battery, plastic, and construction material sectors. With its fully enclosed design, three-dimensional layout capability, low material breakage, and energy efficiency, it effectively addresses the limitations of traditional conveying methods such as belt conveyors, screw conveyors, bucket elevators, and pneumatic conveying systems.
What Is a Tube Chain Conveyor？
A tube chain conveyor is a continuous conveying system that moves materials smoothly inside a sealed round or square tube using a durable chain with evenly spaced discs. Driven by a sprocket system, the closed-loop chain pushes material in stable, continuous columns along horizontal, vertical, inclined, Z-shape, or U-shaped paths. Supporting multi-point feeding and multi-point discharging, it fits perfectly into complex workshop layouts.
Core Components:
- Conveying pipe
- Drive unit
- Tensioning device
- Turning mechanism
- Chain-disc assembly
- Electrical control system
How It Works
The conveying process is gentle, stable, and highly reliable:
- Horizontal Section: Discs push material forward without stratification or blockage.
- Vertical/Inclined Section: Material is lifted steadily by disc support with no spillage.
- Full Enclosure: 100% dust-free and leak-proof, customizable for explosion-proof, corrosion-resistant, or negative-pressure environments.
Its low-impact operation makes it ideal for fragile crystals, sensitive granules, and high-value materials.
Key Advantages
1. Fully Enclosed & Dust-Free
The sealed pipeline ensures zero dust emission, meeting strict environmental, GMP, and ATEX standards. It enhances workplace safety and reduces explosion risks.
2. 3D Flexible Layout
Can turn, climb, and navigate through tight spaces, eliminating the need for transfer stations. Saves up to 30%+ of floor space and reduces construction costs.
3. Low Breakage, High Material Integrity
Gentle handling preserves particle shape, purity, and quality — critical for food additives, pharmaceutical APIs, lithium battery materials, and plastic pellets.
4. Energy Efficient
Consumes 30%–50% less energy than pneumatic conveying, with lower power consumption, minimal wear, and quieter operation.
5. Wide Compatibility & Easy Maintenance
Works with powders, granules, flakes, and slightly sticky materials. Modular design enables fast replacement of chains and discs, simplifying daily maintenance.

Operation & Maintenance Tips
- Regularly inspect chain tension and disc wear.
- Maintain pipeline sealing to prevent foreign object intrusion.
- Lubricate bearings and drive components on schedule.
- Clean sticky materials regularly to avoid blockage.
With proper maintenance, chains and pipes can last for several years, delivering excellent long-term value.
Conclusion
The Tube Chain Conveyor is more than a conveying machine — it is a comprehensive solution for clean production, space optimization, and material protection. As environmental and safety regulations tighten, it has become the preferred choice for stable, flexible, and efficient powder and granule conveying.
If you’re looking to improve conveying efficiency, eliminate dust, protect material quality, or save space, the tube chain conveyor is an investment worth making.
