Industrial Tubular Drag Chain Conveyor for Flour Transfer

Tubular Drag Chain Conveyor Product Introduction

Tube Chain Conveyor is an enclosed material conveying system designed for efficient transportation of powders, granules, and bulk solid materials in complex industrial environments. The conveyor uses a continuous chain equipped with discs running inside a sealed pipeline, pushing materials smoothly through horizontal, vertical, and inclined conveying routes.

The fully enclosed structure prevents dust leakage, reduces environmental pollution, and eliminates the need for additional dust collection equipment in many applications. The unique chain and disc conveying mechanism provides gentle material handling, helping maintain product quality while reducing material loss and segregation.

With flexible configuration options, the system can support multiple feeding points and discharge locations to meet different production requirements. It can be integrated with equipment such as big bag unloading stations, storage tanks, feeders, and automated production lines.

Tubular Drag Chain Conveyor features low power consumption, stable operation, easy maintenance, and strong adaptability, making it suitable for industries including chemical processing, food production, grain handling, mineral processing, and other bulk material handling applications.

Working principle

Tube Chain Conveyor works through a continuous chain and disc conveying mechanism installed inside a closed pipeline.

During horizontal conveying, the discs attached to the moving chain push the material forward. The internal friction between material particles is greater than the friction between the material and the pipe wall, allowing the material layer to move continuously along the pipeline.

During vertical conveying, the discs lift the material upward while preventing material backflow. The interaction between the discs, material particles, and pipeline creates stable continuous transportation.

The enclosed pipeline design allows the conveyor to transport materials safely through complex routes, including horizontal sections, vertical lifting sections, and directional changes.
