When the internal friction between the material layers is greater than the external friction between the material and the pipe wall, the material moves forward with the chain to form a stable flow; when vertically transported, the material particles in the pipe are pushed upward by the chain because the lower part The feeding material prevents the upper material from sliding down, and the lateral side pressure is generated, so the internal friction of the material is enhanced. When the internal friction between the materials is greater than the friction between the material and the inner wall of the tube and the weight of the material, the material is transported upward with the chain. A continuous stream is formed. The inclined conveyance is that the material is driven by both horizontal and vertical forces, and a continuous flow can still be formed.
Therefore, the powder tube chain conveyor can maintain the stability of the conveyance in the three-dimensional variable direction conveying.
