FU drag chain conveyors is used for  continuous conveying of powder and small granular bulk materials. Horizontal or inclined layout,Widely used in metallurgy, building materials, mining, chemical, food, dust removal and other industries。


  1. Large throughput, allowing large quantities of materials to be transported in small capacity space, conveying capacity of 15 ~ 500m3/h.
  2. Low energy consumption, with the help of the internal friction of materials, it is 40% ~ 60% compared to the screw conveyor.
  3. Sealing and safety. The fully sealed shell makes the dust seamless and can be operated safely and reliably.
  4. Long service life, with advanced heat treatment of alloy steel for conveying chain, its normal life is >3 years, and the roller life on chain (according to different materials) is 1 ~ 3 years.
  5. Long transmission length, the horizontal transport distance can be up to 60 meters.
  6. The process layout is flexible, can be elevated, ground, ground pit, climb slope (15) installation, can be more and more in and out of the material.
  7. Low cost, energy-saving and durable, low maintenance rate, lower consumption and higher efficiency.

Working Principle

Powder has the characteristics of internal friction and lateral pressure, it in the machine by the conveyor chain groove in the direction of tension, increase the internal pressure, particle inside between the friction force increases, the level of transportation, ensure the stability of the material between layers within the friction state, formed a continuous flow as a whole. When the internal friction between the material layer is greater than the external friction between the material and the wall, the material moves forward along with the conveyor chain. When the ratio of the height of the material layer to the width of the slot meets certain conditions, the feed flow is stable and the material speed is equal to the chain speed.
FU chain conveyor mainly consists of head wheel, tail wheel, conveyor chain, chassis and driving device. A symmetrical l-shaped round steel is welded at regular intervals on the conveyor chain to drive the material.
