TD Series Bucket Elevator
TD-type bucket elevator is an industrial equipment designed for vertically conveying powdery, granular, and small lump materials with bulk density below 1.5 t/m³, which are non-abrasive or slightly abrasive. It features a rubber belt as traction component, with buckets fixed on the belt to form a closed-loop system. Driven by head and bottom pulleys, the equipment transports materials from the bottom feeding port to the top discharge port.
- High-Efficiency Vertical Conveying
- Low Wear & Extended Lifespan
- Stable & Reliable Operation
- Energy Saving
- Easy Maintenance
- Adaptable Configuration

How It Works
Loading Zone – Material enters through the inlet chute into buckets
Vertical Lift – Driven by heavy-duty chains/belts via head pulley
Discharge – Centrifugal force (high-speed) or gravity discharge (low-speed)
Return Cycle – Empty buckets descend for reloading
