Polyurethane Grinding Jar XN-MJ-PU
SKU: XN-MJ-PU
Polyurethane Grinding Jar XN-MJ-PU is a mold-formed polyurethane (PU) jar for ball-mill grinding, with an extremely smooth surface that keeps material from sticking to the inner and outer walls. It offers higher mechanical strength and oxidation stability, together with higher flexibility and resilience than rigid jars.
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.

Equipment Type: Polyurethane Grinding Jar for Planetary and Ball Mills
Product Code: XN-MJ-PU
Brand: Xnergy
Product Introduction:
The XN-MJ-PU Polyurethane Grinding Jar is a mold-formed polyurethane (PU) jar for ball-mill grinding. Its surface is extremely smooth, so material does not stick to the inner and outer walls during grinding. The jar offers higher mechanical strength and oxidation stability, together with higher flexibility and resilience than rigid ceramic or metal jars — making it a good fit for applications that benefit from a tough yet resilient, low-stick jar. 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
Applications requiring a flexible and resilient jar
Grinding where higher mechanical strength and oxidation stability are needed
Sample preparation benefiting from an extremely smooth, low-stick jar surface
Battery R&D — 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 jar and lid for wear or damage before each run
Avoid excessive heat or sharp impact that could damage the jar
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 jar carefully to avoid damage
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-PU polyurethane jar stands apart from Xnergy’s ceramic and metal jars: it offers higher mechanical strength and oxidation stability together with higher flexibility and resilience, and an extremely smooth, low-stick surface. Where samples are hard or abrasive and call for a rigid, wear-resistant jar instead, the XN-MJ-WC Tungsten Carbide Grinding Jar is the hardest option and the metal-free XN-MJ-ZR Zirconia Grinding Jar the premium ceramic alternative; for general work in a rigid metal jar, the XN-MJ-SS Stainless Steel Grinding Jar is the economical choice. Polyurethane jars run well in roller jar mills such as the XN-GMS-DO Double Station Roller Jar Mill.
