Chain Conveyors — Rugged En-Masse Transport in a Closed Casing
The chain conveyor (redler) drags material through a closed rectangular casing with flighted chain strands — en-masse: the whole material column moves together. That makes it the machine of choice for hot, abrasive and dusty products where belts and screws reach their limits.
Working Principle and Design
Inside the closed casing, a forged-link chain with transport flights moves along the trough bottom. The material fills the casing cross-section and travels as a compact column with minimal internal movement — gentle on the product, contained against dust, and tolerant of high temperatures.
Design revolves around chain selection and wear management: chain breaking load with proper safety factor, hardened links and sprockets, replaceable bottom liners, and correctly engineered inlets that prevent flooding. Multiple inlets and outlets with motorised gates allow one conveyor to serve several silos or process points.
Typical Applications
- Hot product transport after dryers and coolers
- Abrasive minerals and ash handling
- Dusty powders requiring fully enclosed transport
- Distribution over silo groups with multiple outlets
Technical Features
Closed, dust-tight casing
Rectangular casing with gasketed covers and inspection ports.
Heavy-duty chain
Forged links, hardened pins and sprockets sized with verified safety factors.
Wear liners
Replaceable bottom and side liners for abrasive duties.
Multi-point service
Several inlets/outlets with motorised slide gates on one machine.
Data Required for Chain Conveyor Design
| Design input | Role in the calculation |
|---|---|
| Material, temperature, abrasiveness | Chain, liner and casing specification |
| Capacity (t/h) | Casing cross-section and chain speed |
| Route: length, incline | Chain tension and drive power |
| Number of inlets/outlets | Gate configuration and controls |
Chain speed is kept low by design to limit wear; capacity is achieved through cross-section — calculated per project.

Single point of responsibility
Process design, fabrication, automation and commissioning are managed by one engineering team.
Frequently Asked Questions
When is a chain conveyor better than a belt?
When the material is hot, abrasive or dusty, when full enclosure is required, or when several inlets and outlets must be served on one route. Belts win on long distances and gentle handling.
Can chain conveyors run inclined?
Yes, moderate inclines are standard with adapted flight geometry; steeper angles reduce capacity and are evaluated case by case.
How is chain wear managed?
Through hardened chain components, replaceable liners, correct chain speed and tension monitoring. We specify wear parts for your material's abrasiveness.
