What Is an Air Cooling Vertical Spiral Elevator?
An air cooling vertical spiral elevator is a vibrating conveyor that lifts and cools granular or free-flowing bulk materials within the same machine. It consists of a spiral conveying trough arranged around a central column, a vibration drive system, supporting springs and an air cooling assembly. The material travels upward along the spiral path while cooling air passes over or through the material bed, depending on the airflow design.
Also known as an air cooling spiral elevator or air cooling vibrating spiral conveyor, the equipment is commonly used after processes that produce warm granules, including plastic pelletizing and selected chemical processing operations. Its vertical arrangement provides a longer conveying path within a limited floor area.

Working Principle
An air cooling vertical spiral elevator is a vibratory conveying machine that combines vertical material lifting with air cooling and drying. It moves bulk materials upward along a spiral trough while dissipating heat and removing moisture through natural or forced airflow, allowing material conveying and temperature reduction in one continuous process.
- Vibratory Spiral Lifting: Vertically or oppositely arranged vibration motors generate excitation forces that drive materials along the spiral trough, moving them upward or downward in a continuous spiral path.
- Air Cooling & Heat Extraction: As materials travel along the extended spiral path, heat dissipates through natural or forced airflow. An optional negative-pressure exhaust system removes hot air and airborne dust, promoting more uniform cooling and reducing the risk of material agglomeration before further processing.
Structure & Components
An air cooling vertical spiral elevator consists of a spiral conveying assembly, dual vibration motors, vibration isolation springs, supporting base and air cooling components. The spiral trough carries materials upward, while the vibration drive controls their movement and the airflow system removes heat during conveying.
| Component | Function & Features |
|---|---|
| Spiral Conveying Trough | Forms the helical conveying path and carries material from the lower inlet to the upper outlet. |
| Central Support Column | Supports the spiral trough and may incorporate air distribution passages in applicable designs. |
| Dual Vibration Motors | Generate the excitation forces required for upward spiral conveying motion. |
| Vibration Isolation Springs | Support the vibrating assembly and reduce vibration transmitted to the foundation. |
| Cooling Fan / Blower | Supplies cooling air to the conveying path at the selected flow rate. |
| Air Distribution Ducts | Direct cooling air toward the material bed according to the specified cooling arrangement. |
| Material Inlet | Receives granules from upstream equipment and directs them onto the spiral trough. |
| Discharge Outlet | Transfers the elevated material to the next processing stage. |
| Support Base | Provides a rigid foundation for the vibration drive and conveying assembly. |
| Optional Enclosure | Helps contain material and enables suitable ventilation or dust extraction connections. |

Air Cooling System vs. Standard Spiral Conveyor
Both air cooling vertical spiral elevators and standard spiral conveyors use vibratory motion to transport bulk materials vertically. The main difference is temperature control. An air cooling system combines material lifting with heat dissipation, while a standard spiral conveyor is primarily designed for vertical material transfer. Equipment selection depends on material temperature, required cooling performance, conveying capacity, and production line conditions.
Key Differences
| Comparison | Air Cooling Vertical Spiral Elevator | Standard Vertical Spiral Conveyor |
| Main Function | Vertical conveying and material cooling | Vertical material conveying |
| Cooling Method | Natural or forced air cooling | No dedicated cooling system |
| Temperature Control | Designed to reduce material temperature during conveying | No active temperature control |
| Airflow System | Optional cooling fans and exhaust system | Not normally equipped |
| Suitable Materials | Hot pellets, granules, and temperature-sensitive materials | General powders, granules, and bulk solids |
| Material Handling | Continuous spiral conveying with cooling | Continuous spiral conveying |
| Equipment Configuration | Spiral trough with configurable airflow and cooling components | Standard spiral trough and vibration drive |
| Typical Applications | Cooling after extrusion, granulation, or thermal processing | Vertical transfer between processing stages |
| Production Line Integration | Connects cooling with downstream screening, storage, or packaging | Connects upstream and downstream conveying equipment |
Which Spiral Conveyor Should You Choose?
Choose an air cooling vertical spiral elevator when materials require temperature reduction during vertical conveying. For applications involving material transfer without controlled cooling requirements, a standard vertical vibrating spiral conveyor is generally sufficient.
Air Cooling System Features
- Cooling Fan or Blower: Supplies air at the required pressure and flow rate.
- Air Distribution System: Directs cooling air toward the material conveying path.
- Spiral Conveying Trough: Provides continuous material movement and residence time for heat exchange.
- Ventilation Openings: Allow cooling air to reach the material bed where the design provides for it.
- Air Exhaust Arrangement: Removes warmed air from the equipment and can be connected to suitable dust extraction when required.
For temperature-sensitive granules, we recommend confirming material inlet temperature, target outlet temperature and operating capacity before selecting the cooling system. Air cooling with ambient air is not suitable for every temperature requirement.

FAQs
What is an air cooling vertical spiral elevator used for?
An air cooling vertical spiral elevator is used to lift and cool granular materials during continuous processing. Typical applications include plastic pellets, rubber granules and selected chemical or industrial materials that require temperature reduction before screening, storage or packaging.
How does an air cooling spiral elevator reduce material temperature?
The machine moves materials upward along a vibrating spiral trough while cooling air passes through the designed airflow path. Heat transfers from the warm material to the cooler air. Cooling performance depends on material temperature, airflow, residence time and processing capacity.
What is the conveying capacity of an air cooling spiral elevator?
Conveying capacity depends on spiral diameter, trough dimensions, vibration settings and material properties. Sanyuantang’s standard vertical spiral elevator range provides a mechanical basis for equipment selection, but the actual capacity of an air-cooled configuration must be confirmed together with the required cooling performance.
What materials can an air cooled spiral elevator handle?
Suitable materials may include plastic pellets, rubber granules, fertilizer granules, chemical granules and other free-flowing bulk solids. Material size, density, moisture, temperature and sensitivity to airflow should be reviewed before equipment selection.
How much can an air cooling spiral elevator reduce material temperature?
The cooling performance of an air cooling vertical spiral elevator depends on material type, inlet temperature, airflow, conveying capacity, and residence time. In a Sanyuantang plastic pellet cooling project, the material temperature was reduced from 130°C to approximately 35°C, achieving a 95°C temperature reduction during the combined cooling and conveying process. Actual cooling performance varies by application, and the spiral dimensions and airflow system are configured according to the required outlet temperature.
Can the lifting height and cooling airflow be customized?
Yes. Sanyuantang offers customized spiral elevator configurations, including lifting height, spiral dimensions, airflow arrangements and material-contact components. The final specifications are selected according to conveying and cooling requirements.
What is the difference between air cooling and water cooling spiral elevators?
An air cooling spiral elevator removes heat through airflow contacting the material. A water cooling spiral elevator uses a cooling-water circuit and heat-transfer surfaces to remove heat indirectly, with the water separated from the material. Air cooling is suitable where the available cooling air can achieve the required outlet temperature. Water cooling may be preferred when greater temperature control or a different heat-removal capacity is required. The appropriate method depends on the material and operating conditions.
