Vacuum Atmosphere-Protected Ball Mill Jar XN-MJ-VAC
SKU: XN-MJ-VAC
Vacuum Atmosphere-Protected Ball Mill Jar XN-MJ-VAC is used when grinding must be isolated from air, preventing hazards such as oxidation from oxygen contact or explosion from air contact. Its strong sealing also helps control material drying and improve grinding fineness.
The stainless steel body can be lined with nylon, polyurethane, corundum, or other materials to match your sample, and sizes are customizable to suit your mill.

Name: Vacuum Atmosphere-Protected Ball Mill Jar XN-MJ-VAC
Equipment Type: Vacuum / Atmosphere-Protected Ball Mill Jar
Product Code: XN-MJ-VAC
Brand: Xnergy
Product Introduction:
The XN-MJ-VAC Vacuum Atmosphere-Protected Ball Mill Jar is used whenever grinding must be carried out in isolation from air. By sealing the sample away from the surrounding atmosphere, it helps prevent hazards such as oxidation caused by contact with oxygen and explosion caused by contact with air. The sealed design also helps control the drying of materials and improve grinding fineness, while keeping operation convenient and the seal reliable. The jar body is made of stainless steel and can additionally be lined with nylon, polyurethane, corundum (alumina), or other materials, allowing the grinding surface to be matched to the sample. Sizes can be customized to suit the customer’s mill and batch requirements.

Application Areas:
Grinding of air- or oxygen-sensitive materials requiring an isolated atmosphere
Grinding of materials prone to oxidation on contact with air
Grinding of materials that pose an explosion risk on contact with air
Controlled-drying grinding for improved fineness
Battery R&D — grinding of air-sensitive cathode, anode, and related materials
Maintenance:
Clean the jar, lining, and lid thoroughly after each use to prevent cross-contamination
Dry the jar completely before storage
Inspect the sealing surfaces and gaskets for wear or damage before each run
Keep sealing faces clean to maintain reliable air isolation
Safety Notes:
Ensure the jar is properly sealed before milling, especially for air-sensitive samples
Do not exceed the jar’s rated load or the mill’s capacity
Handle the jar and lining carefully to avoid damage that could compromise sealing
Specifications are provided for reference and may be adjusted to suit specific process requirements. Jar size, lining, and configuration are specified at order time.
Note: Specifications listed above are typical and for reference only. Actual performance depends on the material, media, and mill. The XN-MJ-VAC vacuum jar is Xnergy’s atmosphere-protected jar, built for grinding that must be isolated from air — preventing oxidation or air-contact hazards while improving fineness and controlled drying through strong sealing. Its stainless steel body can be lined with the same materials Xnergy offers as standalone jars: nylon (XN-MJ-NY), polyurethane (XN-MJ-PU), or corundum / alumina (XN-MJ-AL), letting you match the grinding surface to your sample. When air isolation is not required, the standard XN-MJ-SS Stainless Steel Grinding Jar is the straightforward choice. Vacuum jars run in planetary mills such as the XN-YXQM Series.
