Manufacturer Enclosed Tubular Chain Conveyor System

Enclosed Tubular Chain Conveyor Product Introduction

The Enclosed Tubular Chain Conveyor is a fully sealed bulk material conveying system designed for powders, granules, pellets, and particles in food, chemical, pharmaceutical, and industrial applications. Using a continuous drag chain structure inside enclosed tubes, the system supports horizontal, inclined, and vertical conveying with low energy consumption and minimal material damage. Its dust-free design helps reduce contamination and improves workplace cleanliness during material transfer. The conveyor is suitable for handling flour, coffee powder, feed, chemicals, fertilizers, and abrasive materials. With flexible layouts, multiple inlet and outlet options, and stable continuous operation, this tubular chain conveyor provides an efficient and reliable solution for modern bulk material handling systems.

Working principle

Step 1: Material Feeding

Bulk materials enter the conveyor pipeline through the inlet hopper or feeding station.

Step 2: Chain and Disc Movement

The motor-driven chain moves continuously inside the enclosed tube with evenly spaced discs attached to the chain.

Step 3: Material Drag Conveying

The discs gently push and drag materials through the pipeline while maintaining stable flow and minimal product damage.

Step 4: Multi-Directional Transportation

Materials can move horizontally, vertically, or at inclined angles according to the production layout requirements.

Step 5: Material Discharge

Bulk materials are discharged smoothly through single or multiple outlet points for downstream processing or packaging.

Step 6: Continuous Closed-Loop Operation

The chain returns to the drive section for continuous conveying cycles with low dust emissions and stable performance.
