Tubular Drag Conveyors

Tubular drag conveyors is a fully enclosed continuous conveying solution that uses a sealed pipeline as the material channel, where circular discs driven by a chain or steel cable move the material forward inside the tube. The system provides smooth and gentle conveying with low energy consumption, making it well suited for powders, granules, flakes, as well as abrasive or fragile materials. During operation, it effectively minimizes dust emissions and product degradation, while delivering high operational reliability. Owing to its robust design and stable performance, it is widely applied in industrial processes with stringent requirements for cleanliness and process integrity.

how it works
The tubular drag conveyors uses a continuous chain or steel cable with spaced discs running inside a sealed pipe to efficiently convey bulk materials. The low-speed rotating discs gently push the materials forward, effectively reducing dust escape, material damage and energy consumption. This closed mechanical conveying system, based on reliable transmission principles, can stably complete material conveying tasks along horizontal, vertical and multi-directional composite paths in harsh industrial environments.

tubular drag conveyors type
The typical layout forms of tubular drag conveyors under different working conditions include vertical lifting, closed loop, spatial turning, Z-type, multi-point inclined and straight conveying, etc.

Frequently Asked Questions

Here are some quick reference sections to answer key technical questions about the product.


What materials can be conveyed?

Most common bulk materials can be handled, including powders, granules, grains, chemical products, wood chips, and plastics. Material size should be compatible with the disc spacing and tube diameter.

Is the conveying process gentle?
Yes. Low-speed, column-type conveying helps reduce product breakage, segregation, and dust generation.


Can the system handle complex layouts?
Yes. The modular design allows horizontal, vertical, and multi-bend configurations to suit complex plant layouts.


What are the advantages compared with pneumatic conveying?
Lower energy consumption, reduced material wear, and more predictable operating and maintenance costs.


What factors determine conveying capacity?
Capacity depends on bulk density, material flow characteristics, tube size, chain speed, as well as the number of bends and vertical lift.


Can it be integrated into existing production lines?
Yes. With properly designed inlets and outlets, the system can be easily integrated with existing equipment and processes.
