Bucket Elevator Manufacturer
Baichy builds TD, TH and NE bucket elevators that lift bulk material vertically at 15–118 m³/h and accept granules up to 60 mm. This page covers the three traction types, the TH series model table from TH160 to TH500, and the sizing data behind it.
What Is a Bucket Elevator and How Does It Lift Material?
A bucket elevator is a continuous vertical conveying device that lifts bulk material from a lower level to a higher level with buckets mounted on a traction component, either a rubber belt or a chain. Three stages do the work.
1. Loading — material enters the lower section through the feed inlet, scooped from the material bed or fed by inflow into the buckets.
2. Lifting — the drive unit turns the head pulley or sprocket and the buckets travel upward inside the casing.
3. Discharging — at the head the buckets invert and material leaves the discharge outlet by centrifugal force or gravity.
The five structural groups are the running components (buckets plus belt, round-link chain or plate chain), the drive unit (motor, reducer, backstop), the upper section (head pulley, discharge outlet, anti-backflow mechanism), the sealed casing, and the lower section (tensioning device, feed inlet).
Which Bucket Elevator Type Fits Your Material: TD, TH or NE?
The traction component decides the type: TD elevators use a rubber belt for mildly abrasive bulk, TH elevators a round-link chain for hot or highly abrasive material, and NE elevators a plate chain for the heaviest loads.
| Traction component | Construction | Material that suits it |
|---|---|---|
| Belt (TD type) | Rubber belt as the traction component, smooth running, low noise | Light material such as grain and plastic pellets |
| Round-link chain (TH type) | Round chain, high strength, wear resistant | Heavy material such as ore and coal |
| Plate chain (NE type) | Plate chain, higher load-bearing capacity | High-temperature material such as cement clinker |
TH Series Bucket Elevator Specifications
The TH series covers five models from TH160 to TH500, with conveying capacity rising from 15–30 m³/h on the TH160 to 75–118 m³/h on the TH500.
| Model | TH160 | TH250 | TH315 | TH400 | TH500 |
|---|---|---|---|---|---|
| Bucket Width (mm) | 160 | 250 | 315 | 400 | 500 |
| Bucket Distance (mm) | 300 | 420 | 500 | 560 | 625 |
| Speed (m/s) | 1.4 | 1.6 | 1.6 | 1.8 | 1.8 |
| Max Granule size (mm) | 25 | 35 | 45 | 55 | 60 |
| High Degree of Appearance (m) | H+0.9 | H+1.2 | H+1.2 | H+1.5 | H+1.5 |
| Conveying Capacity (m³/h) | 15–30 | 31–48 | 35–60 | 60–94 | 75–118 |

Bucket Elevators for Vertical Conveying: TD, TH and NE Types
How Do You Size a Bucket Elevator for a Given Duty?
Size a bucket elevator from three numbers: required capacity in m³/h, maximum granule size in mm and lifting height. A TH315 delivers 35–60 m³/h with 315 mm buckets and accepts granules up to 45 mm.
Match maximum granule size to the model
The granule limit rises with the model: 25 mm on the TH160, 35 mm on the TH250, 45 mm on the TH315, 55 mm on the TH400 and 60 mm on the TH500. Coarser feed bridges at the feed inlet.
Add the height offset to the site height
The height offset runs from H+0.9 m on the TH160 to H+1.5 m on the TH400 and TH500, added to the required lifting height. Baichy bucket elevators cover lifting heights of 40–60 m.
Confirm the discharge method against the material
Centrifugal discharge needs dry, free-flowing feed. Gravity discharge is safer for lumpy, heavy or fragile material, where a thrown discharge generates extra fines.
Where a Bucket Elevator Sits in a Powder Grinding or Cement Line
In a powder grinding plant the bucket elevator lifts crushed material from the storage hopper to the mill feed point, directly upstream of the vibrating feeder.
A powder grinding line runs crusher, bucket elevator, hopper, feeder, mill, classifier and dust collector, with the bucket elevator as the only vertical leg:
• YGM high pressure grinding mill — main mill
• HGM micro-powder grinding mill — fine grinding
• Cement ball mill — clinker grinding
• Screw conveyor — horizontal transfer
• Belt conveyor — long-distance haulage
• Vibrating feeder — controlled feed
• Pulse dust collector — dust control
• YK vibrating screen — sizing
FAQ: Bucket Elevator Selection
1. What is the maximum feed size of a bucket elevator?
The TH series accepts granules up to 60 mm: 25 mm on the TH160, 35 mm on the TH250, 45 mm on the TH315, 55 mm on the TH400 and 60 mm on the TH500.
2. What capacity does a TH315 bucket elevator deliver?
A TH315 delivers 35–60 m³/h with 315 mm buckets, 500 mm spacing and a chain speed of 1.6 m/s. Output varies with material and feed particle size, so the figure is a range.
3. What is the difference between a belt and a chain bucket elevator?
A belt bucket elevator (TD type) runs on a rubber belt and suits light, mildly abrasive material such as grain. A chain bucket elevator (TH or NE type) runs on a round-link or plate chain and suits heavy, hot or abrasive material such as ore and cement clinker.
4. How high can a bucket elevator lift material?
Baichy bucket elevators cover lifting heights of 40–60 m, with the height offset added per model: H+0.9 m on the TH160, H+1.2 m on the TH250 and TH315, and H+1.5 m on the TH400 and TH500.
5. What information does Baichy need to size a bucket elevator?
Material name, maximum granule size in mm, required capacity in m³/h, lifting height and discharge method. Baichy answers technical questions within 30 minutes and returns a design proposal within 24 hours.
