Overview
Vertical Bulk Conveying with Chain and Buckets
A chain bucket elevator is vertical conveying equipment in which buckets fixed to a chain at intervals pick up material at the boot, carry it upwards inside an enclosed casing and discharge it at the head. The chain runs between the drive sprocket or pulley at the top and the take-up unit at the bottom.
Using a chain instead of a belt as the conveying element is a preferred solution for coarse and heavy bulk materials. Chain type, bucket type and bucket spacing are selected according to capacity, lift height, particle size and density.
The feeding arrangement (buckets scooping from the boot or material fed directly into the buckets) and the discharge at the head are determined by the flow behaviour of the material. Build-up and backflow are controlled through boot and head design.
01Process Flow
Chain Bucket Elevator Material Flow
The diagram shows the typical flow in which the chain bucket elevator takes material at the boot inlet and carries it to the head discharge.
Scroll horizontally to view the full diagram.
Material line
- 1
Boot feeding: Material enters the elevator through the inlet at the boot.
- 2
Bucket filling: Buckets on the chain pick up material at the boot.
- 3
Vertical lifting: The chain carries the loaded buckets upwards in the enclosed casing.
- 4
Head discharge: As the buckets turn at the head, material falls into the discharge spout.
The elevator only conveys vertically; conveyors, silos or process equipment before and after it depend on the plant concept.

05FAQ
Chain Bucket Elevator FAQ
What is the difference between a chain and a belt bucket elevator?
Both lift material vertically in buckets. On a chain elevator the buckets are fixed to a chain; on a belt elevator to a rubber or similar belt. The chain design is preferred for coarse and heavy materials.
Can a chain bucket elevator handle hot products?
Suitability for hot products is assessed per project based on chain, bucket and bearing materials and product temperature. Not every chain elevator suits every temperature.
How are bucket type and spacing selected?
Bucket type and spacing are selected according to capacity, particle size, flow behaviour and the feeding and discharge arrangement.
How are backflow and build-up prevented?
Suitable discharge geometry, boot design, chain take-up and, where required, a backstop keep backflow and build-up under control.
What information is needed for a quotation?
Material type, particle size, bulk density, product temperature, hourly capacity and the lift height between inlet and discharge.
