Dust-Free Bulk Material Handling
for Powders, Granules and Bulk Solids

  • Fully Enclosed & Dust-Free
  • Flexible Routing: Horizontal / Vertical / Complex Layouts
  • Multiple Inlets & Outlets
  • Gentle Handling & Low Maintenance

Engineered to Solve Your Handling Challenges

Dust-Free

Fully enclosed conveying helps prevent dust leakage and keeps the working area cleaner.

Gentle Handling

Low-speed conveying helps minimize product breakage and preserve material integrity.

Flexible Routing

Horizontal, vertical, inclined and complex layouts can be designed around your plant.

ϟ

Low Energy

Mechanical conveying can reduce compressed-air demand compared with pneumatic systems.

Multiple Inlets & Outlets

Multi-point feeding and discharging can be configured along the conveying line.

Easy Maintenance

Simple structure with inspection points for cleaning, checking and maintenance.

Typical Conveying Circuits

Adaptable to various plant layouts and process requirements

Typical tube chain conveyor circuits including HVH, loop, inline, U-shape and vertical transfer

How It Works

  1. Material enters the inlet hopper.
  2. Chain with discs moves inside the sealed tube.
  3. Material is gently dragged by the discs.
  4. Conveyed to the designed discharge point(s).
  5. Multiple inlets and outlets can be configured.

Frequently Asked Questions

What is a tube drag chain conveyor?

It is a sealed tube conveying system that uses chain and discs to move powders, granules and bulk solids gently through a designed route.

What materials can be conveyed?

Common materials include chemical powders, food powders, minerals, graphite, titanium dioxide, limestone powder, additives and granules.

Can it convey abrasive materials?

Yes. Pipe thickness, chain design and wear-resistant options can be selected according to the material.

How far and how high can it convey?

The final distance and height depend on material properties, capacity, route layout and number of bends. UNITFINE engineers can help calculate the solution.

How many inlet and outlet points can be installed?

Multiple inlets and outlets can be configured for storage silos, mixers, packaging lines or process equipment.

What are the advantages over screw conveyors?

A tube chain conveyor offers more flexible routing, sealed dust control, longer complex routes and multiple discharge options.
