Name: Semi-Circular Planetary Ball Mill XN-BQM Series
Equipment Type: Compact Benchtop Planetary Ball Mill with Semi-Circular Cover and Four Grinding Modes
Product Code: XN-BQM
Brand: Xnergy
Product Introduction:
XN-BQM Series Semi-Circular Planetary Ball Mill is a compact benchtop planetary ball mill characterized by its distinctive semi-circular acrylic cover, which gives the operator full visibility into the grinding chamber while keeping the unit’s footprint minimal. The series includes two models — XN-BQM-0.4L (50–100 mL grinding jars, 50 mL vacuum jar) and XN-BQM-1L (50–250 mL grinding jars, 50–100 mL vacuum jars) — sized for laboratories where bench space is at a premium. The same four grinding modes available on larger Xnergy planetary mills are supported: dry, wet, vacuum, and protective atmosphere.
Key Features:
Distinctive semi-circular acrylic cover for clear visibility into the grinding chamber
Compact “Mini model” footprint at 64–65 kg — designed for benchtop laboratory use
Four grinding modes — dry, wet, vacuum, and inert (protective) atmosphere
Oil-seal silent design — lower operating noise and longer service life than conventional planetary ball mills
Self-locking safety door that opens only when the machine is stopped
Caster wheels for easy repositioning in the lab
Digital screen display with one-button operation
Programmable timer with up to 15 saved programs
Power-off memory with self-restart after power restoration
Sun-wheel speed 5–450 rpm; jar speed 10–900 rpm
Available in two models (XN-BQM-0.4L and XN-BQM-1L)
Series Specifications:
| Model | Grinding Jar Size | Vacuum Jar Size | Sun Wheel Speed | Jar Speed | Power | Weight |
|---|---|---|---|---|---|---|
| XN-BQM-0.4L | 50 – 100 mL | 50 mL | 5 – 450 rpm | 10 – 900 rpm | 0.55 kW | 64 kg |
| XN-BQM-1L | 50 – 250 mL | 50 – 100 mL | 5 – 450 rpm | 10 – 900 rpm | 0.55 kW | 65 kg |
The two models share the same drive and control platform; the difference is total grinding-jar capacity. Power supply is configurable to local electrical standards.
Operating Modes:
Dry grinding — for dry powder size reduction, mixing, and alloying
Wet grinding — for slurry milling, particle-size reduction in solvent, and dispersion
Vacuum grinding — using vacuum jars for oxygen-sensitive materials or for de-gassing during grinding
Protective-atmosphere grinding — under inert gas inside the jars for moisture- and oxygen-sensitive chemistries such as lithium metal, sodium metal, sulfide solid electrolytes, and reactive powders
Application Areas:
XN-BQM Series is suitable for:
Small-batch lithium-ion and sodium-ion battery active-material development — powder size reduction, surface coating, mechanochemical activation
Sulfide and oxide solid-electrolyte preparation at lab-scale where atmosphere control is critical
Nano-powder grinding and dispersion at gram-scale R&D quantities
Bench-space-constrained laboratories needing planetary milling capability without floor-standing equipment
Mechanochemical synthesis of intermetallics, alloys, and composite materials
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
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
Specifications are provided for reference and may be adjusted to suit specific process requirements. Grinding jars and grinding media are specified at order time according to the target material and process.
Note: Specifications listed above are typical and for reference only. Actual grinding performance depends on input material properties, grinding-media selection, jar-fill ratio, and process parameters. XN-BQM Series is the benchtop-format member of Xnergy’s planetary ball mill range — its semi-circular acrylic cover and compact 64–65 kg weight make it the lightest planetary mill in the catalog, ideal when bench space and lab-bench visibility matter more than batch size. For larger jar volumes up to 1 L grinding-jar and 500 mL vacuum-jar, or for higher-throughput milling workflows, step up to the floor-standing XN-ZQM Planetary Ball Mill (2 L and 4 L models). Milled powders typically proceed to slurry preparation — for small R&D batches use the XN-PVM-500mL, and for contamination-sensitive samples use the bladeless XN-PVMC-150mL centrifugal mixer. For active materials commonly milled with this equipment, see our Cathode Materials and Anode Materials ranges (including metallic lithium and sodium metal series).
