Enclosed Low-Degradation Bulk Transport for Powders & Granules
The FU Series Chain Conveyor (En-Masse Drag Conveyor) utilizes the internal friction of bulk solids to transport continuous material columns inside a sealed rectangular trough. Moving powders and small granular particles as a single continuous stream rather than in individual batches, it minimizes particle degradation, segregation, and mechanical vibration. It provides dust-tight conveying across throughput capacities reaching up to 420 m³/h along horizontal or slightly inclined layouts up to 15°.
Core System Advantages
En-Masse Continuous Flow: Exploits internal material friction to move continuous product streams, cutting power consumption by up to 40% while preventing fine-particle segregation.
Low Particle Degradation: Low-speed flight transport (0.16–0.32 m/s) preserves material structure and eliminates product breakage during continuous conveying.
Dust-Tight & Sealed Casing: Fully enclosed design prevents dust leakage, maintaining clean workplace air quality and protecting sensitive materials from contamination.
Key Technical Specifications
Conveying Capacity & Distance: Handles throughput volumes from 10 to 420 m³/h over distances up to 60 meters and incline angles from 0° to 15°.
Chain & Liner Construction: Built with wear-resistant 20Mn2, 40Cr, or 20CrMnTi alloy chains supported by UHMW-PE or NM400 abrasion-resistant wear plates.
Operating Limits & Drives: Operates at chain speeds of 0.16–0.32 m/s for bulk densities from 0.2 to 1.8 t/m³, powered by high-torque 1.5 kW to 37 kW gear motors.

How Does an FU Chain Conveyor Work? (Working Mechanism)
The FU chain conveyor operates on the principle of en-masse conveying:
A high-strength alloy chain moves inside a sealed rectangular trough.
Scraper plates attached to the chain push material forward.
Bulk materials form a moving column (the "en-masse" effect).
Friction between particles allows the entire material bed to flow uniformly.
Material discharges steadily at the outlet.
This simple, robust mechanism ensures:
