Zirconia Grinding Jar XN-MJ-ZR
Zirconia Grinding Jar XN-MJ-ZR is a mold-formed zirconia (zirconium oxide) ceramic jar for ball-mill grinding, with extremely smooth inner and outer walls that keep material from sticking. This tough, dense, metal-free ceramic offers high wear resistance, chemical corrosion and inorganic-acid resistance, and high-temperature resistance, and is non-toxic and tasteless.
A large-radius (R-angle) bottom reduces material build-up for high grinding efficiency and long service life. Supplied with a matching lid, and sizes are customizable to suit your mill and sample.

Name: Zirconia Grinding Jar XN-MJ-ZR
Equipment Type: Zirconia Ceramic Grinding Jar for Planetary and Ball Mills
Product Code: XN-MJ-ZR
Brand: Xnergy
Product Introduction:
The XN-MJ-ZR Zirconia Grinding Jar is a mold-formed zirconia (zirconium 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 tough, dense, metal-free ceramic, it delivers high wear resistance, chemical corrosion resistance, inorganic-acid resistance, and high-temperature resistance, while remaining non-toxic and tasteless — making it the premium choice for high-purity, contamination-sensitive grinding. 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.

Application Areas:
Grinding jar for planetary and roller ball mills
High-purity, metal-free grinding of contamination-sensitive samples
Grinding of hard materials that need a tough, dense ceramic
Grinding in the presence of inorganic acids or corrosive chemistry
Non-toxic grinding for food, pharmaceutical, and other sensitive applications
Battery R&D — high-purity 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-ZR zirconia jar is the premium, toughest, and densest ceramic — metal-free and non-toxic — so it suits the most demanding high-purity grinding, including food and pharmaceutical work. Zirconia is also the standard media for wet nano-grinding, making it a natural complement to the XN-MS Nano Sand Mill for ultra-fine work. For small, high-value samples, run it on the XN-GMS-SI Single Station Roller Jar Mill; for a more economical metal-free ceramic on routine jobs, the XN-MJ-AL Alumina Grinding Jar is the step down. It is widely used to grind high-purity Anode Materials without contamination.
