FIG. 01 — GENERAL ARRANGEMENT, CENTRIFUGAL BUCKET ELEVATOR
What is a Centrifugal Discharge Bucket Elevator?
A centrifugal discharge bucket elevator uses high belt/chain speed to generate centrifugal force at the head pulley, throwing material from the buckets into the discharge chute without the bucket needing to tip. This makes it the highest-throughput, lowest-cost bucket elevator type for free-flowing bulk materials.
How centrifugal discharge works
Buckets are spaced apart on the belt or chain, typically one to two bucket widths apart. As the belt runs at high speed, typically 1.0–2.0 m/s, the loaded buckets travel upward inside the sealed casing. At the head pulley, the combination of the pulley's rotational speed and the belt velocity creates centrifugal force, throwing material out of the bucket and into the discharge chute before the bucket has even rounded the top of the pulley. No bucket tipping is required.
When centrifugal discharge is the correct choice
Centrifugal discharge is correct for free-flowing, granular, or fine bulk materials not degraded by the centrifugal throw at discharge, cement, fly ash, grain, fertilizer, sand, coal dust, limestone powder, and mineral powders. It is not correct for fragile materials, sticky materials, or materials with high segregation sensitivity, which require the continuous discharge type instead.

How a Centrifugal Bucket Elevator Works
Four stages, from material infeed at the boot to centrifugal discharge at the head, that must all be precisely engineered for rated TPH without spillage or belt slip.
Boot — Material Infeed & Bucket Filling
Material enters the boot section through a feed inlet. As buckets travel past the boot pulley, they scoop material from the boot, filling each bucket with a metered charge. Fill factor is typically 75–85% for centrifugal type.
Vertical Lift — Carrying Run
Loaded buckets travel upward inside the sealed casing on the carrying run of the belt/chain, preventing dust emission during the lift. Belt speed is higher than continuous type, typically 1.0 to 2.0 m/s, to generate sufficient centrifugal force at the head.
Head — Centrifugal Discharge
At the head pulley, the combination of pulley rotation and belt speed generates centrifugal force. This force throws material out of each bucket and into the discharge chute before the bucket rounds the top.
Return — Empty Buckets
Empty buckets return downward inside the same sealed casing on the return run, preventing spillage and dust emission. Belt cleaners at the head remove any material adhering to the belt before return.
Advantages of Centrifugal Discharge Bucket Elevators
Five engineering advantages that make the centrifugal discharge type the most widely used bucket elevator in Indian cement, power, grain, and fertilizer industries.
High Capacity Material Handling
High belt/chain speed and spaced buckets achieve the maximum TPH per unit of casing cross-section, 2–3× the throughput of a continuous type elevator of the same casing size, at lower construction cost.
Continuous Material Flow
Continuous belt motion means continuous material flow from boot to discharge, no intermittent stop-start that batch conveying systems require.
Reduced Operating Costs
Lower cost per tonne elevated than pneumatic conveying, skip hoists, or screw elevators for equivalent capacities and heights.
Compact Vertical Design
The smallest floor footprint of any conveyor system for equivalent TPH and lift height.
Suitable for Fine Bulk Materials
Reliably handles fine powders, granular materials, and small-lump materials, where troughed belts would scatter and pneumatic systems would require high pressure.
Fully Enclosed Dust-Free Operation
Complete casing from boot to head with sealed joints eliminates dust emission during lifting.
Materials Suitable for Centrifugal Discharge Bucket Elevators
Centrifugal discharge is the correct choice for free-flowing, granular, and fine bulk materials, where the centrifugal throw at discharge does not cause unacceptable degradation or dust generation.
Cement
Raw meal, cement powder, and OPC/PPC at raw mill, kiln, and packing plant discharge points.
Fly Ash
ESP and bag filter fly ash at thermal power plants and cement plants.
Coal
Coal dust and small-lump coal at power plants, cement kilns, and chemical plants.
Fertilizer
Urea, DAP, MOP, and NPK granules at blending plants and bagging lines.
Grain
Wheat, rice, maize, soybean, and pulses at grain silos and mills.
Sand
Dry sand, silica sand, and foundry sand at mixing and processing plants.
Mineral Powders
Limestone powder, barite, calcium carbonate, gypsum, and talc.
Salt & Sugar
Industrial salt and refined sugar at processing and packing plants.
Not suitable for: large-lump clinker, minerals above 50 mm lump size, fragile materials, or sticky/wet materials. For these, the Continuous Discharge Bucket Elevator is the correct choice.

Frequently Asked Questions
What is a centrifugal discharge bucket elevator?
A centrifugal discharge bucket elevator is a high-speed vertical conveyor that uses buckets attached to a belt or chain to lift bulk materials, throwing material into the discharge chute at the head using centrifugal force rather than tipping.
How does it differ from a continuous discharge elevator?
Centrifugal discharge elevators run at high speed for free-flowing materials; continuous discharge elevators run slowly and tip gently, suited to fragile materials.
What materials can centrifugal discharge bucket elevators handle?
Cement powder, fly ash, raw meal, coal dust, limestone dust, grain, sugar, salt, fertilizer, sand, and mineral powders. Not suitable for large lumps, fragile, or sticky materials.
What capacities are available?
Up to 200 TPH and up to 40 metres lift height as standard, with custom designs for greater heights and capacities.
When should I choose belt type over chain type?
Belt type for temperatures below 80°C and low-to-moderate abrasiveness; chain type for higher temperatures or high abrasiveness.
Can it be customised?
Yes, height, capacity, drive type, bucket material, casing material, and motor are all specified per project with a GA drawing included.
