Mini screw feeder

The Most Reliable Desktop Screw Feeder for Global Production

Stable Powder Feeding at 1 g/min

Minimal Moving Parts

We have physically eliminated common failure points by streamlining the internal mechanism. Fewer moving parts mean less wear, ensuring long-term stability without the need for periodic adjustments.

High-Grade Japanese Components

Every unit is engineered and manufactured in Japan using premium, wear-resistant materials. Our strict quality control guarantees a “set-and-forget” experience even in demanding environments.

100% Tool-Free Interface

No specialized tools or local technicians are required. Our intuitive design allows any operator to disassemble and clean the unit in seconds, eliminating dependency on external support.

4 Screw Types for Every Need

1.Standard screw(Most Versatile)Ideal for a wide range of materials.

2. Double-Start (High Precision) Best for stable, small-volume output.

Double start screw

3. Coreless (Anti-Clogging) Ideal for sticky or adhesive materials.

Hollow screw

4. Spring (Anti-Jamming) Best for pellets and granular materials.

Solution Options for Specific Requirements

Agitator model

Anti-Bridging: Best for sticky or fine powders. Internal blades ensure consistent material flow into the screw.

Vibrator model

Contamination Control: External vibration assists flow without internal contact, ideal for high-purity applications.

Customized model

Custom Integration: Custom pressure-resistant housings, ferrule welding, and tailored interface connections.

KF Flange Connection
For easy integration with vacuum systems, glove boxes, and closed process equipment.

Air Purge Port
Helps maintain powder condition by reducing moisture absorption and exposure to air.

Extended Screw Outlet
Allows the feeder to discharge directly into downstream equipment while minimizing powder loss.

Discharge Mesh Screen
Prevents large agglomerates from entering next equipment and helps achieve a more consistent powder flow.

Proven Performance: Feed Rates by Material Density

Estimated Feeding Capacity

The following data represents typical feed rates based on material density. Actual capacity may vary depending on material flowability.
*Note: These values are for reference only. We recommend a feeding test with your actual material for precise calibration.

Material Category Bulk Density Max Feed Rate Characteristics
Carbon Powder 0.16g/cm³ 2.0 kg/h Ultra-light / High bridging risk
Slaked Lime (Hydrated Lime) 0.50g/cm³ 3.0 kg/h Fine powder / Cohesive
Iron Powder 3.00g/cm³ 17.0 kg/h High density / Free-flowing
