What is an FU Chain Conveyor?
An FU chain conveyor which is also known as an FU type drag chain conveyor or en masse conveyor . This chain conyeyor is also a high efficiency material handling system engineered for the horizontal or inclined transport up to 15° of bulk materials such as powders, granules and small particles. The system operates on the en masse conveying principle where the material is moved as a continuous and solid mass within a fully enclosed casing by means of a precision engineered chain fitted with conveying flights.
The FU chain conveyor is generally used for cement, grain, coal, fly ash, chemical, minerals and similar materials that require dust free conveying, stable flow and long service life. Here in Hebei OuTai Environmental Protection Equipment Co., Ltd. Our FU chain conveyors deliver exceptional reliability including energy efficiency and dust free operation that making them ideal for industries such as cement, construction, thermal power, chemicals, food processing, machinery and mining.

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:
