Mini screw feeder

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.

Maintenance-Free Design. No Specialist Needed. Built for Independent Operation.

Watch how simple it is: Tool-free disassembly in under 30 seconds!

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
