This jar is designed exclusively for horizontal roller jar mills and requires specific grinding media and operating conditions. Improper use can lead to jar failure, contamination, or safety hazards.
- Temperature Constraint: Do not operate above 120°C as prolonged high temperature accelerates aging, softening, and cracking of the polyurethane elastomer.
- Chemical Compatibility: Avoid concentrated strong acids, strong alkalis, and strong corrosive solvents that can corrode the PU surface and cause jar damage.
- Grinding Media Restriction: Use only polyurethane-coated iron core balls or nylon balls; do not use corundum, zirconia, or cemented carbide balls which can rapidly scratch through the jar wall.
- Equipment Compatibility: This jar is strictly for horizontal roller jar mills and roller ball mills; it is not suitable for planetary ball mills due to high-speed centrifugal impact.
- Inspection and Replacement: Discard jars showing cracking, peeling, or inner wall scratching to avoid debris contamination and ensure safe operation.
Follow these steps to safely operate the jar while avoiding damage and contamination. Proper preparation and media selection are critical for optimal performance.
Required Equipment: Horizontal roller jar mill
- Inspect the jar
Inspect the jar for any cracks, peeling, or damage before each use. - Select grinding media
Select only polyurethane-coated iron core balls or nylon balls as grinding media to avoid jar wall damage. - Secure the lid
Secure the threaded compression lid with the built-in gasket to ensure leak-proof operation. - Verify temperature
Verify that the operating temperature will remain below 120°C to prevent jar softening or cracking. - Confirm equipment compatibility
Confirm that the jar is used exclusively on a horizontal roller jar mill, not on a planetary ball mill.
How does the polyurethane roller grinding jar's soft cushioning affect grinding efficiency for brittle materials compared to harder jars?
The jar's flexible PU material (Shore A 85–95) provides cushioned impact that prevents lithium battery slurries, pigments, and heat-sensitive powders from being excessively crushed, preserving crystal structure and electrochemical performance. However, it is not suitable for ultra-hard material ultrafine grinding or planetary ball mills, as it lacks strong crushing capability and will tear under high-speed centrifugal impact.
Can the Atomfair PU grinding jar be used with zirconia grinding balls in a roller mill?
No. The manufacturer strictly prohibits corundum, zirconia, and cemented carbide balls because their hardness far exceeds PU (Shore A 85–95) and will rapidly scratch through the jar wall during high-speed rolling, generating massive PU debris contamination. Only polyurethane-coated iron core balls (IC-PU) and nylon balls are recommended.
What are the maximum operating temperature and chemical exposure limits for the polyurethane roller grinding jar to prevent failure?
The operating temperature range is -20°C to 120°C; prolonged operation above 120°C causes softening, cracking, swelling, and jar failure. The jar resists oils, weak acids/alkalis, and common organic solvents, but is not resistant to concentrated strong acids/strong alkalis/strong corrosive solvents such as concentrated HCl, NaOH, or HF, which will corrode the PU surface.
Polyurethane roller grinding jar with Shore A 85-95 hardness, available in 100ml-10L, provides zero metal contamination and low noise for gentle dispersion of heat-sensitive and brittle materials, but requires exclusive use on roller jar mills with specific soft grinding media and cannot tolerate high temperatures above 120°C or strong corrosive chemicals.
Positive
- Zero metal contamination for high-purity applications: The fully polymer-based jar eliminates Fe, Al, Zr, and other metal impurity release, making it suitable for lithium battery, precious metal, and high-purity applications where metal contamination must be avoided.
- Low noise operation reduces lab noise: The elastic PU buffer layer dramatically reduces operating noise compared to stainless steel and ceramic jars, creating a quieter laboratory environment and minimizing spindle and roller wear.
Trade-offs
- Limited to roller jar mills only: This jar is designed exclusively for horizontal roller jar mills and roller ball mills; use in planetary ball mills is strictly prohibited as high-speed centrifugal impact will tear the jar body.
- Restricted grinding media compatibility: Only polyurethane-coated iron core balls (IC-PU) and nylon balls are recommended; corundum, zirconia, and cemented carbide balls will scratch through the jar wall, generating massive PU debris contamination.
