Description
360° Rotating Planetary Ball Mill
- Product Name
360° Omnidirectional Laboratory Planetary Ball Mill, 360° Rotating Planetary Ball Mill
- Working Principle
Based on a vertical planetary ball mill, this equipment adds a planetary disk overturning function.While performing planetary motion, the planetary disk and grinding jars can carry out 360° tipping overturning in threedimensional space, realizing multidimensional and multidirectional movement of the jars.This enhances the disordered motion of grinding balls and materials, enabling 360° grinding inside the jar for finer and more uniform powder, and solves the problems of material sedimentation and wall adhesion.

Store the ball mill in a dry, climate-controlled environment to prevent corrosion of electrical components and mechanical wear. Ensure the installation surface can support the 1180 kg dead weight and anchor the machine to avoid tipping during operation.
- Electrical Safety: Ground the equipment per local electrical code and avoid exposure to conductive dust or moisture to prevent short circuits.
- Mechanical Hazard: Lock the overturning brake before loading or unloading grinding jars to prevent unintended rotation.
- Material Compatibility: Do not process pyrophoric or explosive materials unless the grinding jar is rated for inert atmosphere and sealed under inert gas.
- Ventilation: Operate in a well-ventilated area or under a fume hood when grinding materials that produce hazardous dust or vapors.
Initialize the mill by verifying jar integrity and setting parameters via the touchscreen. Execute the grinding cycle with the overturning function enabled to achieve 360° particle reduction.
Required Equipment: Microcomputer touch screen controller, Grinding jars with sealing gaskets, Grinding media (balls or rods)
- Inspect and seal
Inspect the grinding jars for cracks or wear, then load material and grinding balls up to two-thirds of jar volume and seal the lids tightly. - Set rotation parameters
Set the jar rotation speed (0–430 rpm) and grinding time using the microcomputer touch screen, and select forward or reverse alternating mode if required. - Engage overturning brake
Confirm the overturning motor brake is engaged before mounting jars onto the holders to prevent accidental tipping. - Load jars into holders
Secure the grinding jars into the jar holders and tighten the clamps evenly to ensure balanced rotation. - Activate overturning
Enable the 360° overturning function from the touch screen to allow the planetary disk to tip during operation. - Start grinding cycle
Initiate the grinding cycle and monitor the display for abnormal vibration, noise, or temperature rise. - Unload after stop
Allow the mill to come to a complete stop before disengaging the brake and removing the jars to avoid spillage or injury.
How does the 360° rotating design of the QXQM-20 affect its maximum grinding speed compared to conventional planetary ball mills with the same jar capacity?
The 360° rotating design limits the maximum jar rotation speed to 430 rpm for the QXQM-20, lower than smaller models like the QXQM0.4 at 870 rpm. This reduction accommodates the larger jar orbit diameter of 385 mm and the mechanical demands of the overturning mechanism, ensuring stable anti-sedimentation and anti-adhesion operation without compromising the ability to reach discharge fineness down to 0.1 μm.
What are the critical considerations when selecting grinding jar material for battery cathode materials like lithium cobalt oxide or lithium manganate in the QXQM-20 mill?
For battery cathode materials sensitive to Fe/Cr/Ni contamination, 304 stainless steel jars are explicitly contraindicated. The QXQM-20 should be equipped with high-purity ceramic jars such as zirconia or alumina, which provide the necessary hardness and wear resistance to avoid ion leaching while achieving the specified discharge fineness down to 0.1 μm, as stated in the jar compatibility table.
What are the infrastructure requirements for installing the QXQM-20 planetary ball mill, particularly regarding floor loading and electrical supply?
The QXQM-20 has a net weight of 1180 kg and overall dimensions of 1700×1210×1300 mm, necessitating a reinforced floor rated for that static load plus operational vibration. A dedicated electrical circuit is required for the 4 kW motor with inverter-driven stepless speed control, and adequate clearance must be maintained around the unit to safely accommodate the 360° overturning motion and gear drive system.
The Atomfair QXQM-20 360° Rotating Planetary Ball Mill delivers a 4KW motor and 385mm revolution diameter, enabling fine powder down to 0.1μm while its omnidirectional jar overturning effectively prevents sedimentation and adhesion during high-energy milling of ceramics and nanomaterials.
Positive
- Anti-sedimentation and anti-adhesion via 360° overturning: The planetary disk overturns 360° in three-dimensional space, enhancing disordered motion of grinding balls and materials to eliminate material sedimentation and wall adhesion inside the jar.
- High power and large orbit for industrial batch processing: A 4KW motor with 385mm revolution diameter supports jar volumes up to 25L per jar (total 100L), making it suitable for large-scale grinding of electronic ceramics, battery materials, and nanomaterials.
Trade-offs
- Substantial weight and floor space requirement: With a net weight of 1180 kg and dimensions 1700×1210×1300 mm, this unit demands reinforced flooring and dedicated installation space, typical for industrial-scale milling equipment.
- Limited feed size necessitates pre-processing: Feed size is restricted to ≤3mm for most materials (soil ≤10mm), requiring pre-crushing or milling of larger feedstocks before charging the mill.
