Working principle of FU chain conveyor

There is internal friction and pressure between the particles in the bulk material. When the conveyor chain and its accessories move, the bulk material is subjected to a tensile force in the same direction as the conveying motion in the machine slot of the conveyor, which increases the internal pressure between the particles and thus increases the internal friction between the particles. When the internal friction force is greater than the friction force between the bulk material and the side wall of the machine slot, the bulk material will move forward along the direction of the conveyor chain, and the increased internal pressure stabilizes the interlayer of the bulk material, thus forming a continuous flow as a whole, like water flow. When the ratio of the material layer height to the machine slot meets specific conditions, the material flow is stable and the material speed is approximately equal to the chain speed.

The FU chain conveyor can transport over a thousand types of materials, including powder, granular, and small pieces. Typical examples include:
Cement finished products, cement raw materials, yellow sand, limestone powder, coal powder, coke powder, fly ash, sawdust, crushed ice, stone powder, urea, synthetic fertilizers, soap powder, soda ash, soda ash, graphite, plastic pellets, polyethylene, resin, potassium sulfate, ammonium sulfide, clay powder, quartz powder, iron ore powder, crushed slag, salt, starch, wheat, cottonseed, crushed feed, maltose, rice, corn, soybeans, etc.
