A bucket elevator's performance comes down to matching bucket size, belt/chain speed, height, and construction material to your actual material and required throughput — not selecting a standard model number off a catalogue. Here's what to check.
Performance Specifications
ENZAC's standard bucket elevator range:
- Maximum height: ≤20m standard
- Capacity range: 1–15 m³/hr
- Belt speed: 9–11 m/min
- Motor power: 0.75–7.5 kW, VFD speed control
Model Range (DY Series)
| Model | Bucket Volume | Capacity | Motor |
|---|---|---|---|
| DY-2L | 1.8 L | 1–5 m³/hr | 0.75–7.5 kW |
| DY-4L | 4 L | 2–8 m³/hr | 0.75–7.5 kW |
| DY-6L | 6 L | 5–15 m³/hr | 0.75–7.5 kW |
Bucket volume is the primary lever for capacity within a fixed height and speed — larger buckets move more material per cycle, but the right model also depends on your material's bulk density, since capacity ratings are typically based on standard bulk density assumptions.
Design Configuration
The standard configuration is a Z-type bucket elevator, which "receives material at floor level, conveys it horizontally, then lifts vertically to the discharge point — without intermediate transfers." This layout is what makes the bucket elevator such an efficient floor-space solution compared to an inclined mechanical conveyor covering the same height gain.
Discharge is either centrifugal (buckets throw material out at speed around the head pulley — standard, higher-capacity) or continuous/gentle (lower-speed, guided discharge for friable or degradation-sensitive materials) — a separate decision from height and capacity that should be made against your material's fragility.
Construction Materials
- Buckets: ABS, stainless steel 304, or carbon steel
- Frame: stainless steel 304 or carbon steel
Bucket material selection should reflect both your material's abrasiveness (carbon steel wears faster under abrasive duty than SS304) and hygiene requirements (ABS or SS304 for food-contact or corrosion-sensitive applications).
What Determines Real Capacity
The 1–15 m³/hr range isn't a single number for any given elevator — actual throughput depends on:
- Bucket volume — the primary driver within the DY-2L/4L/6L range
- Belt or chain speed — within the 9–11 m/min range, higher speed increases throughput but also increases centrifugal discharge force, which matters for fragile materials
- Material bulk density — capacity is normally rated by volume (m³/hr), so converting to tonnes/hr requires your material's actual bulk density
- Fill efficiency — how completely buckets fill at the intake, which depends on material flowability and how material is fed into the boot section
What to Send With Your Enquiry
A complete bucket elevator spec starts with: material bulk density and particle characteristics, required height, required throughput (m³/hr or t/hr), whether the material is friable or degradation-sensitive (affecting discharge type), and any hygiene or corrosion requirements affecting bucket and frame material. Review the full Bucket Elevator specification range before finalising a transfer method for your line.
