Alumina Grinding Jar XN-MJ-AL

Name: Alumina Grinding Jar XN-MJ-AL
Equipment Type: Alumina Ceramic Grinding Jar for Planetary and Ball Mills
Product Code: XN-MJ-AL
Brand: Xnergy

Product Introduction:

The XN-MJ-AL Alumina Grinding Jar is a mold-formed alumina (aluminum oxide) ceramic jar for ball-mill grinding. Its inner and outer walls are extremely smooth, so material does not stick to the walls during grinding. As a metal-free ceramic, it resists a wide range of solvents, withstands strong acids and alkalis, and offers good collision (impact) resistance along with strong oxidation resistance — making it well suited to chemically aggressive and contamination-sensitive samples. The bottom is formed with a large R-angle to reduce material sinking and build-up while grinding, supporting high grinding efficiency and a long service life. The jar is supplied with a matching lid, and sizes can be customized to suit the customer’s mill and batch requirements.

Technical Specifications:

Application Areas:

Grinding jar for planetary and roller ball mills
Metal-free grinding of contamination-sensitive samples
Grinding in the presence of strong acids, alkalis, or solvents
Use where smooth, non-stick walls reduce material loss and ease cleaning
Custom sizes to match specific mill models and batch volumes
Battery R&D — metal-free grinding of cathode, anode, and precursor powders

Maintenance:

Clean the jar and lid thoroughly after each use to prevent cross-contamination
Dry the jar completely before storage
Inspect the sealing surface and lid for chips or cracks before each run
Avoid impact, thermal shock, or dropping that could chip or crack the ceramic

Safety Notes:

Ensure the lid is properly sealed before milling
Do not exceed the jar’s rated load or the mill’s capacity
Handle the ceramic jar carefully to avoid chipping or breakage

Specifications are provided for reference and may be adjusted to suit specific process requirements. Jar size 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-AL alumina ceramic jar is a metal-free option that resists acids, alkalis, and solvents — ideal where metal contamination must be avoided and the chemistry is aggressive. For the hardest, most wear-resistant grinding, the XN-MJ-WC Tungsten Carbide Grinding Jar is the choice; for general corrosion- and high-temperature-resistant grinding, the XN-MJ-SS Stainless Steel Grinding Jar; and for an even tougher, denser ceramic, a zirconia jar is the alternative. These jars run in planetary ball mills such as the XN-YXQM Series and roller jar mills like the XN-GMS-SI Single Station Roller Jar Mill.
