PTFE Grinding Jar XN-MJ-PTFE
SKU: XN-MJ-PTFE
PTFE Grinding Jar XN-MJ-PTFE is a mold-formed PTFE (polytetrafluoroethylene) jar for ball-mill grinding, with extremely smooth, non-stick inner and outer walls that keep material from sticking. This metal-free fluoropolymer offers wear resistance, corrosion resistance, and high-temperature resistance, making it well suited to chemically aggressive samples.
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: PTFE Grinding Jar XN-MJ-PTFE
Equipment Type: PTFE Grinding Jar for Planetary and Ball Mills
Product Code: XN-MJ-PTFE
Brand: Xnergy
Product Introduction:
The XN-MJ-PTFE PTFE Grinding Jar is a mold-formed PTFE (polytetrafluoroethylene) jar for ball-mill grinding. Its inner and outer walls are extremely smooth and non-stick, so material does not stick to the walls during grinding. As a metal-free fluoropolymer, it offers wear resistance, corrosion resistance, and high-temperature resistance — making it well suited to grinding highly corrosive or chemically aggressive samples without metal contamination. 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
Grinding of highly corrosive or chemically aggressive samples
Metal-free, contamination-free grinding
High-temperature grinding applications
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 sharp impact or excessive mechanical stress 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-PTFE jar is the chemical-inertness specialist among Xnergy’s jars — a metal-free, non-stick fluoropolymer with wear, corrosion, and high-temperature resistance, ideal for grinding highly corrosive or chemically aggressive samples without contamination. Because PTFE is comparatively soft, hard or abrasive samples are better ground in a rigid, corrosion-resistant ceramic: the economical XN-MJ-AL Alumina Grinding Jar or the tougher, denser XN-MJ-ZR Zirconia Grinding Jar. For a more rigid, higher-strength polymer jar for general work, see the XN-MJ-NY Nylon (MC) Grinding Jar. PTFE jars run well in planetary mills such as the XN-YXQM Series.
