Description

OPBM-16 360° ROTATING PLANETARY BALL MILL 3KW Φ320MM

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.

Applications

This equipment requires a stable, grounded electrical connection and must be operated with all safety guards in place to prevent injury from rotating components. Grinding jars must be loaded within the specified two-thirds volume limit to maintain operational safety and prevent jar failure.

  • Electrical Safety: Operate only with a properly grounded power outlet rated for the specified motor power to mitigate electrical shock risk.
  • Mechanical Integrity: Ensure all protective covers and interlocks are in place before initiating rotation to prevent injury from moving parts.
  • Jar Loading Limitation: Do not exceed two-thirds of jar volume for combined material and grinding ball loading to maintain safe operation and effective grinding.
  • Overturning Brake Engagement: Confirm the overturning brake is fully engaged before accessing the grinding jars to prevent unintended movement.
  • Operational Environment: Do not operate the mill in the presence of flammable dusts or vapors due to potential ignition from electrical sparks or friction.

This procedure outlines safe setup and operation of the ball mill for grinding powders. Follow each step in sequence to ensure proper function and avoid equipment damage or personal injury.

Required Equipment: Grinding jar set including jars, lids, and media

  1. Inspect equipment
    Inspect the mill for any visible damage, loose components, or debris on the planetary disk and jar holders before use.
  2. Load grinding jars
    Load the grinding jars with material and balls up to two-thirds of jar volume and securely tighten the jar lids.
  3. Set rotation parameters
    Set desired rotation speed, direction, and time via the microcomputer touch screen interface.
  4. Initiate grinding cycle
    Press start on the touch screen and allow the mill to begin planetary rotation with 360° overturning motion.
  5. Monitor and stop
    Monitor the operation for unusual noise or vibration; after the set time, the mill will stop automatically or can be stopped manually via the screen.
  6. Secure and unload
    Engage the overturning brake lock before opening the lid and then carefully remove the grinding jars from the holders.

How does the 360° rotation of the QXQM-16 planetary ball mill improve grinding uniformity compared to standard planetary mills without overturning?

The 360° planetary disk overturning eliminates material sedimentation and wall adhesion by continuously reorienting the jar in three-dimensional space. This ensures that grinding balls and powder remain in constant disordered motion, achieving finer and more uniform particle size distribution down to 0.1 μm without the need for process interruptions to scrape walls.

Can the QXQM-16 be used for grinding lithium-ion battery cathode materials without iron contamination?

No, the standard QXQM-16 is equipped with 304 stainless steel jars which can introduce Fe, Cr, and Ni contamination, making it unsuitable for high-purity battery materials. For lithium cobalt oxide or lithium manganate, you must select non-metallic jars such as zirconia ceramic or agate, which are available as supplementary products from the manufacturer.

What are the electrical and space requirements for installing the QXQM-16 3KW ball mill?

The QXQM-16 requires a 3KW motor with stepless speed regulation via a brand inverter, and its overall dimensions are 1530×1018×1100 mm with a net weight of 580 kg. Ensure the installation area can support this weight, has adequate ventilation for heat dissipation from the 3KW motor, and access to a compatible power supply for the inverter.

The QXQM-16 360° rotating planetary ball mill delivers anti-sedimentation grinding with a 3KW drive and jar capacities up to 25L, but requires substantial bench space (1530x1018x1100mm) and pre-crushing of feed materials, as maximum feed size is 10mm for soil and 3mm for other materials.

Positive

  • Anti-sedimentation 360° grinding action: The planetary disk and jars perform 360° overturning in three-dimensional space, preventing material sedimentation and wall adhesion for finer, more uniform powder.
  • High capacity and throughput scalability: With a 3KW motor, jar volumes up to 25L each, and support for two or four jars simultaneously, this model bridges lab-scale and pilot-scale milling needs.

Trade-offs

  • Large footprint and weight: Overall dimensions of 1530×1018×1100 mm and a net weight of 580 kg require dedicated floor space and a robust installation surface.
  • Feed particle size restrictions: Maximum feed size is 10 mm for soil and only 3 mm for other materials, typically necessitating pre-crushing of larger feedstocks.

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.
