Precision Metal Powder Classification for 3D Printing

Backed by decades of industry-proven field performance, Hosokawa Alpine designs cutting-edge powder processing technology for global manufacturing industries.

Engineered for extreme cut-point precision and effortless maintenance, our air classifiers are specifically tailored to meet the strict quality standards of metal powder production in additive manufacturing.

OPTIMAL CLASSIFICATION FOR HIGH-QUALITY METAL POWDERS

While conventional sieving systems can remove coarse particles after metal powder atomization, they fall short when you need flexible separation cuts, inert gas purging, or rapid product switchovers.

The Hosokawa Alpine Turboplex ATP Air Classifier overcomes these limitations:

  • Flexible Separation Cuts: Adjust particle size thresholds smoothly between 5 and 120 µm.

  • Scalable Capacity: Available in multiple sizes to seamlessly match your atomizer’s output rate.

  • Inert Gas Compatible: Designed for safe, continuous operation with argon or nitrogen.

Closed-Circuit Processing Systems

We engineer tailored, closed-circuit solutions designed specifically for your production requirements:

  • Ultra-Low Oxygen Environments: Operates continuously under inert gas with minimal O2 concentrations.

  • On-the-Fly Adjustments: Modify separation cut-points digitally without opening the sealed system.

  • Consistent Powder Quality: Achieves precise fine-particle removal and steep particle size distribution curves.

  • Sealed & Safe: Dust- and gas-tight construction protects operators and product purity.

  • Rapid Product Changes: Easy-clean, low-dead-space design minimizes cross-contamination during batch changeovers.

  • Custom Docking & Sampling: Optional gas-tight docking systems and integrated sampling units for quality control.

SINGLE-STAGE OR TWO-STAGE CLASSIFICATION

Whether you require a filterless circulating-air system or a two-stage inert gas process, our engineering team will build the ideal configuration for your operational goals.

  • Key Capabilities:

    • Continuously Adjustable Cuts: Fine-tune particle sizes dynamically from 5 to 120 µm.

    • High Material Yield: Sharp cut-points maximize usable metal powder recovery.

    • CMR Containment: Specialized options available for handling hazardous, carcinogenic, or reactive materials safely.
