Description

OPBM-(2-6) 360° ROTATING PLANETARY BALL MILL 0.75KW Φ234MM

LABORATORY GRADE EQUIPMENT

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 three-dimensional 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. The listed price is for the main machine only; grinding jars and grinding balls must be ordered separately.

This planetary ball mill operates with a 360° rotating planetary disk and gear drive, requiring stable electrical supply and secure placement. The overturning motor brake locking mechanism must be engaged before any maintenance or jar removal.

  • Loading Constraint: The total volume of grinding balls and material must not exceed two-thirds of the jar capacity to prevent overloading and mechanical stress.
  • Speed Operation: Jar rotation speed should be set within the specified range for the model using the microcomputer touch screen to avoid excessive vibration or damage.
  • Overturning Lock: The overturning motor brake must be engaged to lock the planetary disk at the desired angle before jar access.
  • Electrical Safety: The equipment must be connected to a properly grounded power source matching the motor power rating (250W to 11KW as per model).
  • Jar Compatibility: Only jars with the specified inner diameter (from 80 mm to 326 mm) and volume range (0.05L to 25L) should be used.

Follow these steps to initialize grinding with the 360° rotating planetary ball mill. Ensure all safety precautions are observed before operation.

Required Equipment: Planetary ball mill unit with touch screen controller, Grinding jars and lids, Grinding balls and material

  1. Inspect Equipment
    Inspect the grinding jars, lids, and jar holders for any cracks or damage before loading.
  2. Load Jars
    Load the grinding balls and material into the jar, ensuring total volume does not exceed two-thirds of the jar capacity.
  3. Secure Jars
    Secure the jar lids tightly and place the jars into the jar holders, verifying proper alignment.
  4. Configure Parameters
    Set the jar rotation speed, grinding time, and forward-reverse alternating cycle using the microcomputer touch screen interface.
  5. Start Grinding
    Initiate the grinding cycle by pressing the start button on the touch screen, and monitor operation for any abnormal noise or vibration.

What is the relationship between feed size and achievable discharge fineness for the QXQM-(2-6) planetary ball mill?

The QXQM-(2-6) accepts soil feed up to 10 mm and other materials up to 3 mm. It can achieve discharge sizes down to 0.1 μm, but the final fineness varies by material type and grinding process, as stated in the technical parameters.

Which grinding jar materials are compatible with the QXQM-(2-6) for processing lithium-ion battery cathode materials without contamination?

For battery materials such as lithium cobalt oxide or lithium manganate, use non-metallic jars like agate, alumina corundum ceramic, or zirconia ceramic to avoid metal ion contamination. Stainless steel jars are contraindicated for high-purity materials sensitive to iron, chromium, or nickel, as noted in the jar caution table.

What are the space, weight, and safety requirements for installing the QXQM-(2-6) 360° rotating planetary ball mill?

The unit measures 1330×810×860 mm and weighs 305 kg, requiring a sturdy, level surface. The overturning motor includes brake locking for safe stopping at any angle. Ensure adequate clearance around the machine for the 360° rotation and verify the gear drive is properly engaged before operation.

The Atomfair QXQM-(2-6) 360° Rotating Planetary Ball Mill leverages a gear-drive transmission and omnidirectional jar overturning to eliminate sedimentation and wall adhesion, enabling submicron particle sizes down to 0.1 μm. However, its batch throughput is constrained by a maximum fill volume of two-thirds per jar, and feed materials must be pre-crushed to ≤3 mm (or ≤10 mm for soils) before milling.

Positive

  • 360° rotation prevents sedimentation: The planetary disk and jars undergo full three-dimensional overturning, eliminating material settling and wall adhesion, which yields finer, more uniform powder compared to conventional planetary mills.
  • Precision gear drive for stable operation: CNC-machined gears made from special materials deliver stable, low-noise, high-speed performance, ensuring reliable long-term operation in industrial or laboratory settings.

Trade-offs

  • Limited jar fill volume: Maximum loading of material plus grinding balls is restricted to two-thirds of jar volume, reducing effective batch capacity per grinding cycle.
  • Strict feed size requirements: Feed size must be ≤3 mm for most materials (≤10 mm for soil); larger particles require pre-crushing, adding a preprocessing step.

Every advanced material, component, equipment, and instrument in our catalog is backed by rigorous testing. We maintain strict internal quality management frameworks and align with CE conformity metrics to deliver transparent, reproducible performance data via our public open-science repository.
