How Does a TD Bucket Elevator Work?
The working mechanism of a TD bucket elevator involves continuous material lifting through buckets attached to a belt or chain:
Material Feeding: Material enters via gravity or a feed chute into the bottom boot section.
Elevating Action: Buckets scoop the material and move vertically upward along the casing.
Discharge: At the top head section, the material is discharged either by centrifugal force or gravity, depending on elevator type.
Return Path: Empty buckets return down through the casing to restart the cycle.
Tension Adjustment: Spring-loaded or screw-type tensioning rollers maintain optimal belt/chain alignment.
This simple yet efficient cycle ensures smooth, continuous operation with minimal spillage or blockage.
