Drag Chain Conveyor

 Drag chain conveyor is a continuous conveying equipment used for transporting dusty, small granular, and small blocky bulk materials, capable of horizontal, inclined, and vertical conveying. During conveying, the drag chain is completely buried in the material, hence the name drag chain conveyor. Bulk materials possess characteristics such as internal friction and lateral pressure. During horizontal conveying, the material is subjected to the thrust force of the drag chain in the direction of motion. When the internal friction between the material layers is greater than the external friction between the material and the wall of the trough, the material moves forward with the drag chain. When the ratio of the material layer height to the trough width meets certain conditions, the material flow is stable.
