Vacuum Feeder Machine
The Vacuum Feeder Machine is designed for automatic conveying of powders, granules, and small bulk materials through a closed vacuum suction system. This machine uses vacuum pressure to draw materials from source containers and transfer them directly into processing equipment.
Because the transfer happens in a sealed pipeline, it helps reduce dust contamination, material loss, and manual handling. These systems can typically convey materials over several meters and accommodate a wide range of substances, from fine powders to free-flowing granules.

- Automatic Material Transfer: Material is transferred using a vacuum suction system, which reduces the need for manual loading. This keeps production more consistent and helps improve workflow.
- Dust-Free Feeding System: The sealed conveying pipeline prevents dust leakage during operation. It is especially useful in pharmaceutical and food environments where cleanliness is important.
- Compact and Easy to Install: Designed with a small footprint, the machine can be placed near mixers, hoppers, or filling machines without requiring major layout changes.
- Low Maintenance Design: Fewer moving parts and simple operation help reduce maintenance requirements and keep downtime minimal.
- Suitable for Powders and Granules: Processes a broad spectrum of materials, from powders to granules. Enables flexible use across different production lines.

A vacuum feeder (also called vacuum conveyor) is a closed conveying system that transports powder, granule, pellet, and small flake materials automatically using negative pressure. It is widely used in pharmaceutical, food, chemical, plastic, battery material, and cosmetic industries.
- Fine powder: flour, starch, milk powder, chemical powder, pigment, toner.
- Granules: plastic pellets, sugar, salt, coffee beans, rice.
- Special materials: lithium battery powder, metal powder, abrasive powder.
Normally 50–5000 kg/h(large volume must be customized), depending on:
- Material density and fluidity.
- Conveying distance (vertical / horizontal).
- Pipe diameter.
- Vacuum pump power.
Yes. It uses a fully closed conveying system to prevent dust leakage, cross-contamination, and material waste. It meets GMP and food safety standards.
Electric vacuum pump models have low noise (around 60–75 dB). Mufflers can be installed for quieter operation.
Yes. We offer explosion-proof vacuum feeders with Ex-proof motors, anti-static pipes, and ground wires.
