Description
360° Rotating Planetary Ball Mill
- Product Name
360° Omnidirectional Laboratory Planetary Ball Mill, 360° Rotating Planetary Ball Mill

This machine requires secure placement on a stable, grounded surface and operation within a dry, well-ventilated environment to prevent electrical hazards. All grinding jars must be sealed and loaded to no more than two-thirds of their volume to avoid mechanical overload and material leakage.
- Loading Limitation: Do not exceed two-thirds jar volume when loading material and grinding balls to prevent mechanical stress and inefficient grinding.
- Brake Engagement Protocol: Engage the overturning motor brake before stopping or reversing direction to maintain safe, controlled positioning.
- Containment Requirement: Ensure all jar lids are properly tightened and sealed to contain fine powders and prevent exposure to hazardous materials.
- Electrical Safety: Connect the machine to a properly grounded electrical outlet rated for 1.5 kW to avoid overheating or electrical shock.
This procedure covers loading, programming, and initiating a grinding run on the 360° rotating planetary ball mill. Follow these steps to ensure safe operation and optimal powder processing.
Required Equipment: Grinding jars (0.05 L–25 L capacity as per model), Grinding balls (appropriate size and quantity for sample)
- Load the grinding jars
Fill each jar with material and grinding balls up to two-thirds of the jar volume, then seal the lid tightly. - Secure jars in the machine
Place the loaded jars into the jar holders and lock them in place using the clamping mechanism provided. - Set grinding parameters via touch screen
Use the microcomputer touch screen to input the desired rotation speed, grinding time, and forward/reverse alternating cycle. - Initiate and monitor grinding
Start the machine and observe for any abnormal vibration or noise during the first minute of operation, then allow the run to complete.
How does the maximum rotation speed of the QXQM-(8-12) 360° planetary ball mill compare to smaller models, and what is the impact on grinding fineness?
The QXQM-(8-12) model operates at a maximum jar rotation speed of 580 rpm, lower than the 870 rpm of the QXQM0.4, due to its larger jar orbit diameter of Φ275 mm compared to Φ140 mm. This trade-off enables processing medium-to-large batch samples with total jar capacities from 0.2L to 100L while still achieving discharge fineness down to 0.1 μm, depending on material and process.
Can the QXQM-(8-12) be used for lithium battery cathode material grinding without iron contamination?
For grinding lithium battery cathode materials such as lithium cobalt oxide or lithium manganate, contamination from metal ions like Fe, Cr, or Ni must be avoided. The QXQM-(8-12) is compatible with high-purity ceramic jars—zirconia or agate—that eliminate metal ion contamination, whereas stainless steel jars are explicitly cautioned against for battery materials due to sensitivity to Fe/Cr/Ni.
What are the electrical, spatial, and safety considerations when installing the QXQM-(8-12) 360° planetary ball mill?
The QXQM-(8-12) requires a 1.5 kW power supply and a floor footprint of approximately 1360 mm × 850 mm, with the unit weighing 430 kg. Its 360° rotation mandates adequate overhead and lateral clearance to accommodate jar overturning, and the built-in brake-locking mechanism on the overturning motor allows safe stopping at any angle for jar changes and maintenance.
The Atomfair QXQM-(8-12) planetary ball mill features a 360° rotating mechanism that minimizes sedimentation and wall adhesion, suitable for medium-to-large batch grinding. However, users must observe feed size and loading constraints to optimize performance.
Positive
- 360° Planetary Overturning Reduces Sedimentation: The planetary disk overturning function enables multidimensional movement, preventing material sedimentation and wall adhesion, leading to finer and more uniform powder.
- Versatile Jar Material Compatibility: The mill supports a wide range of jar materials (agate, zirconia, stainless steel, etc.) allowing users to select appropriate contamination control for different sample types.
Trade-offs
- Feed Size Limitation: Maximum feed size is restricted to ≤3mm for most materials and ≤10mm for soil, requiring pre-crushing for larger particles.
- Limited Maximum Loading Capacity: The combined volume of material and grinding balls must not exceed two-thirds of the jar volume, limiting batch throughput per cycle.
