Vertical Conveyors and Elevators We Manufacture
Compare the conveying method first, then select the lift height, throughput and material-contact construction.
Vibrating Spiral Elevator
Reference lift: up to 8 m · 100–2,000 kg/h
Vibration moves powder, granules and small pieces upward along a spiral chute. The conveying action can suit products where particle shape and controlled handling matter.
Air Cooling Vertical Spiral Elevator
Combined lifting and cooling
Raise hot granules while cooling them along the spiral path. Airflow, residence time and dimensions are selected around the inlet temperature, target outlet temperature and throughput.
Stainless Steel Bucket Elevator
Enclosed casing · Stainless steel contact parts
For suitable food ingredients, chemical granules and other materials requiring controlled contact surfaces. Define cleaning access, seals and material grade for the application.
Bucket Elevator
Chain or belt drive · Bulk material lifting
Buckets carry material upward and discharge at the head of the elevator. Bucket size, speed, lift height and drive are selected for the material, flow rate and plant layout.
Vibrating Spiral Elevator or Bucket Elevator: Which Should You Choose?
Consider a vibrating spiral elevator for a lift within the reference 8 m range, especially for powders, granules or products that benefit from controlled handling. Consider a bucket elevator for a taller lift or larger bulk flow. Selection also depends on density, flowability, temperature and feeding conditions.
| Selection Factor | Vibrating Spiral Elevator | Bucket Elevator |
|---|---|---|
| How it lifts | Vibration moves material along a spiral chute around a central tower | Buckets on a chain or belt carry material upward and discharge at the top |
| Lift height | Reference models up to 8 m | Selected for the required lift and installation layout |
| Capacity | 100–2,000 kg/h reference range | Selected by bucket size, speed and material density |
| Typical materials | Powders, granules, small pieces and suitable fragile products | Grain, sugar, fertilizer, resin, mineral powder and other suitable bulk materials |
| Material handling | No rotating screw within the conveying bed | Handling depends on bucket design, speed and discharge method |
| Temperature control | Air cooling or water cooling configurations can be considered | Separate temperature-control requirements need project review |
| Drive | Two vibration motors on reference spiral models | Motor and gearbox, with chain or belt transmission |
Choose by Lift Height
Check the vertical distance between the inlet and outlet, overall headroom and support space. Within the reference spiral range, compare chute diameter and flow; for a taller route, review bucket elevator options.
Choose by Material
Provide particle size, bulk density, moisture, flowability and sensitivity to breakage. Hot material needs a temperature review. Food or pharmaceutical use needs defined contact materials and cleaning requirements.
Choose by Capacity
Spiral reference capacity is stated in kg/h. Bucket elevator capacity may be stated in m³/h. Convert volumetric flow using the actual bulk density before comparing the two.
Vibrating Spiral Elevator Models and Lifting Height
These reference spiral elevator models use different chute diameters and vibration motor sizes. Choose the model around the material, target flow and required inlet-to-outlet height.
| Model | Chute Diameter (mm) | Lifting Height (m) | Speed (r/min) | Double Amplitude (mm) | Power (kW) |
|---|---|---|---|---|---|
| SZC300 | 300 | ≤ 4.0 | 960 | 6–8 | 2 × 0.4 |
| SZC500 | 500 | ≤ 6.0 | 960 | 6–8 | 2 × 0.75 |
| SZC600 | 600 | ≤ 8.0 | 960 | 6–8 | 2 × 1.5 |
| SZC800 | 800 | ≤ 8.0 | 960 | 6–8 | 2 × 2.2 |
| SZC900 | 900 | ≤ 8.0 | 960 | 6–8 | 2 × 3.0 |
| SZC1200 | 1,200 | ≤ 8.0 | 960 | 6–8 | 2 × 4.5 |
| SZC1500 | 1,500 | ≤ 8.0 | 960 | 6–8 | 2 × 5.5 |
Figures are reference model data. Actual throughput and conveying performance depend on material properties, feeding and operating conditions. Other dimensions and inlet or outlet positions can be reviewed for the production layout.
Bucket Elevator Capacity and Lifting Height
Specify a bucket elevator by the required flow and inlet-to-outlet height. Bulk density connects the volumetric capacity in m³/h with the mass flow in t/h. Bucket filling, speed and discharge behavior also affect the operating capacity.
Bucket Elevator Selection
Information for a Bucket Elevator Configuration
Provide the material and layout data together so the drive, buckets and casing can be selected as a system.
| Selection Factor | Information Required | Design Consideration |
|---|---|---|
| Material | Name, particle size, bulk density and moisture | Flowability, abrasiveness and sticking risk |
| Capacity | Required t/h or m³/h | Include the bulk density and feeding rate |
| Lift and layout | Inlet and outlet elevations; available space | Allow for the head, boot and maintenance access |
| Contact construction | Carbon steel or required stainless steel grade | Define cleaning, seals and contamination-control needs |

Spiral Chutes, Drive Systems and Equipment Checks
Spiral Chute and Material Path
A spiral chute guides material around the central tower. Trough geometry, contact finish and access for cleaning should match the product. Areas where powder can collect need particular attention when defining the equipment construction.
Vibration Drive and Support Arrangement
Spiral elevators use paired vibration motors and an isolation arrangement to produce the conveying motion. Motor position and structural details vary by model. Review the installation space, support loads and access for service as part of the layout.
For a bucket elevator, review bucket and casing clearances, belt or chain alignment, drive operation and inspection access. Agree on the required inspection records and any trial-operation video when defining the order scope.
Vertical Conveying Equipment FAQ
What is the difference between a vibrating spiral elevator and a bucket elevator?
A spiral elevator moves material up a vibrating spiral chute and suits powders, granules and suitable small pieces. A bucket elevator lifts material in buckets attached to a chain or belt. Compare them using the lift height, material properties and required flow.
