Name: Circulating Cooling Planetary Ball Mill XN-XH-XQM Series
Equipment Type: Planetary Ball Mill with Integrated Chiller for Low-Temperature Nano-Scale Grinding
Product Code: XN-XH-XQM
Brand: Xnergy
Product Introduction:
XN-XH-XQM Series Circulating Cooling Planetary Ball Mill integrates planetary ball-mill grinding with a built-in air-cooled chiller and PLC-programmable frequency-controlled temperature regulation, designed for low-temperature nano-scale grinding of heat-sensitive materials. Chamber temperature is adjustable between 1 °C and 30 °C, with stable rapid cooling provided by an industrial-grade compressor. Automatic cold-air circulation inside the chamber recovers cooling capacity and significantly reduces operating costs compared to single-pass cooling. The patented oil-seal silent technology lowers operating noise by more than 50% versus conventional planetary mills while doubling service life.
Key Features:
Built-in air-cooled chiller — chamber temperature adjustable 1 – 30 °C
Industrial compressor delivers stable performance and rapid cooling
PLC-programmable temperature control with automatic frequency conversion
Automatic cold-air circulation and recovery inside the chamber — reduces operating cost
Oil-seal silent design — approximately 50% lower noise and roughly 2× service life versus conventional planetary mills
Four grinding modes — dry, wet, vacuum, and inert (protective) atmosphere
Eight models from 2 L to 100 L total capacity
Available in both laboratory and mass-production configurations
Suitable for ultra-fine grinding, temperature-sensitive materials, and materials prone to wall adhesion or caking from heat buildup

Operating Modes:
Dry grinding — for dry powder size reduction, mixing, and alloying
Wet grinding — for slurry milling and dispersion
Vacuum grinding — using vacuum jars for oxygen-sensitive materials or de-gassing during grinding
Protective-atmosphere grinding — under inert gas inside the jars for moisture- and oxygen-sensitive chemistries
Low-temperature grinding — combine any of the above modes with PLC temperature control between 1 °C and 30 °C
Application Areas:
XN-XH-XQM Series is suitable for:
Lithium-ion and sodium-ion battery active-material development where heat buildup degrades the powder or distorts particle morphology
Sulfide solid-electrolyte preparation, where many sulfide chemistries are temperature-sensitive
Polymer-electrolyte and polymer-composite grinding, where the polymer softens or melts at room temperature
Pharmaceutical and biological samples that require controlled-temperature processing
Materials prone to wall adhesion or caking from frictional heat generated during high-energy grinding
Ultra-fine nano-scale grinding workflows where extended grinding time would otherwise raise sample temperature out of range
Maintenance:
Clean the equipment regularly with a soft cloth lightly moistened with alcohol
Lubricate moving parts periodically to ensure smooth operation
If the equipment is not used for an extended period, clean the moving surfaces and apply a protective anti-rust coating
Periodically inspect screws, nuts, pins, and other fasteners to prevent loosening
Inspect jar seals (especially vacuum jars) before each atmosphere-controlled run
Keep the air-cooler intake and exhaust clear of obstructions to maintain cooling performance
Safety Notes:
Do not open the safety door while the machine is running — the door is interlocked but should not be forced
Operation should be performed by a single trained operator
Disassembly should only be performed by qualified technicians
For vacuum and inert-atmosphere modes, verify jar seal integrity before starting a run
For mass-production models, verify three-phase electrical installation and floor-load capacity before commissioning
Specifications are provided for reference and may be adjusted to suit specific process requirements. Grinding jars, grinding media, and chiller configuration are specified at order time according to the target material and process.
Note: Specifications listed above are typical and for reference only. Actual grinding and cooling performance depend on input material properties, grinding-media selection, jar-fill ratio, ambient conditions, and process parameters. XN-XH-XQM Series is the only planetary ball mill in Xnergy’s range with integrated temperature control — what distinguishes it is not grinding mechanism but thermal management. For sulfide solid electrolytes, polymer composites, and any material whose particle morphology, surface chemistry, or polymer-phase behavior is altered by frictional heat above ambient, the 1 – 30 °C PLC temperature window is the difference between a usable and a degraded product. For workflows that do not have a thermal sensitivity, the conventional full-range XN-YXQM Series covers the same 0.4 – 100 L envelope at lower cost without cooling. For “no dead angle” 360° tilting motion combined with conventional vertical-planetary mechanics, see the XN-QM-QX Full Direction Series. For mechanical alloying and rapid sub-micron grinding at 1600 rpm jar speed, see the XN-MAX1600 Ultra High Energy Ball Mill. Milled powders typically proceed to slurry preparation — for laboratory batches use the XN-PVM-500mL or the bladeless XN-PVMC-150mL; for pilot and production batches, use the XN-PVM-5L or XN-PVM-10L. For active materials commonly milled with this equipment, see our Cathode Materials and Anode Materials ranges (including metallic lithium, sodium metal, and lithium alloy series).
