1.1 Pipe Chain Conveyor
Pipe Chain Conveyor, as an emerging conveying equipment in the conveying industry, has been applied in more and more industries. Pipe chain conveyor is a continuous conveying equipment for powder, small granule and bulk materials, which can be transported horizontally, inclined and vertically in combination. In the closed pipe, the material is driven along the pipe with the chain piece as the driving member. When conveyed horizontally, the material particles are pushed by the chain piece in the direction of movement. When the internal friction between the material layer is greater than the external friction between the material and the pipe wall, the material moves forward with the chain piece to form a stable material flow; when conveying vertically, the material particles in the pipe are pushed upward by the chain piece because the lower feeding prevents the upper material from sliding downward, which produces transverse lateral pressure, and therefore enhances the internal friction of the material. When the internal friction between the materials is greater than the external friction between the materials and the inner wall of the tube as well as the self-weight of the materials, the materials will be conveyed upward with the chain piece to form a continuous flow.
