MSK-JB-500-LD Jet Mill with Glovebox and Inert Gas Purification System for Air-Sensitive Powder Micronization
The MSK-JB-500-LD is engineered to address the challenge of micronizing air-sensitive metallic powders without exposure to oxygen or moisture. It operates within a sealed glovebox environment maintained at ultra-low oxygen and water vapor levels (below 1 ppm), enabling safe and contamination-free milling. This system is ideal for producing fine powders with particle sizes typically between 2 and 15 microns, suitable for advanced material research and manufacturing applications.
The jet mill uses high-purity nitrogen or argon gas at controlled pressures (0.6 to 1.0 MPa) to accelerate particles for impact grinding. The integrated glovebox includes a purification system that continuously removes oxygen and moisture, ensuring the inert atmosphere required for sensitive materials. The system’s cyclone separator efficiently collects milled particles, while an air filter captures fine particulates above 2 microns, maintaining clean exhaust conditions.
Wichtigste Merkmale
- Jet milling performed under a controlled inert atmosphere inside a glovebox with O2 and H2O levels below 1 ppm.
- High-efficiency gas-solid cyclone separator for effective particle collection.
- Adjustable automatic powder feeder using vibration frequency control (40-400 Hz) for consistent feed rate.
- Pressure control system manages gas intake and exhaust to maintain stable milling conditions.
- Mill liner constructed from fully sintered high-purity alumina for chemical resistance and durability.
- Output particle size range from 2 to 15 microns, dependent on input particle size and material hardness.
- Glovebox equipped with multiple KF40 ports for electrical and gas feedthroughs, including valves for pressure regulation.

Typische Anwendungsbereiche
This jet mill system is suited for micronizing air-sensitive metallic powders and other materials that require processing in an inert atmosphere to prevent oxidation or moisture contamination. It is commonly used in advanced materials research, battery electrode preparation, and specialty powder production where fine particle size and high purity are critical.
Hinweise zur Konfiguration und zum Betrieb
Optional accessories include a pre-crusher to reduce particle size before jet milling and a sieving system (MSK-SYU-3) to ensure input particle size meets the 100-200 mesh requirement. The glovebox features multiple KF40 ports for electrical and gas feedthroughs, including valves for controlled gas release. Operators should ensure the inert gas supply meets purity and pressure specifications and monitor glovebox atmosphere to maintain low oxygen and moisture levels during operation.
