Key Features & Advantages
  • High-Efficiency Planetary Grinding with 0.1 μm Output: The revolution plus rotation planetary motion delivers high energy density and three-dimensional movement trajectories, achieving ultrafine grinding efficiency far exceeding traditional equipment with minimum particle sizes down to 0.1 μm.
  • Four-Station Simultaneous Sample Processing: The standard four-position grinding configuration enables parallel preparation of four different samples in a single experiment, significantly improving research throughput for comparative material studies.
  • Vacuum Atmosphere Grinding Compatibility: Optional vacuum grinding jars enable inert gas or vacuum atmosphere grinding for air-sensitive materials, with models from 0.4A supporting 50 mL vacuum jars up to 16A supporting 1–3 L vacuum jars.
  • Intelligent Programmable Control with Safety Protection: Frequency conversion stepless speed regulation, programmable bidirectional rotation timing (1–999 min intervals), LED digital display, safety lock switch, and overload protection ensure reproducible experiments compliant with laboratory safety standards.

APPLICATION SCOPE: Material science research including nanomaterials, composite materials, and metal/non-metal ultrafine powder preparation. Pharmaceutical applications including drug mixing, cell disruption, and biological sample pretreatment. Ceramic and glass industries for raw material uniform dispersion and ceramic slurry preparation. Electronics and metallurgy fields for metal powders, semiconductor materials, and magnetic material fine grinding. Environmental and agricultural sectors for soil/geological sample testing, solid waste treatment, and agricultural product quality inspection. Supports both dry and wet grinding processes.
PACKAGING: This listing is priced for the SPBM-0.4A main unit only. The standard configuration includes 1 pc grinding host machine with four-station platform, frequency conversion speed control, and programmable timing/bidirectional rotation. Grinding jars (Al₂O₃, PU, PTFE, Ceramic, SS, Nylon) and grinding balls (WC-Co, Al₂O₃, PU-Fe, Agate, YSZ, HCCI, 304SS) are ordered separately. Vacuum grinding jars are available as optional accessories. The SPBM-A series is available from 0.4 L through 16 L models. Installation guidance and operational training support are provided upon request.
IMPORTANT NOTICE: The listed price is for the SPBM-0.4A main unit; grinding jars and balls must be ordered separately. Select jar and ball materials compatible with your target material to avoid cross-contamination. The safety lock switch must be engaged before operation. For vacuum grinding, ensure proper vacuum jar sealing before initiating the grinding cycle. Operating noise is 58 ± 5 dB. For detailed installation, operation, and maintenance instructions, consult the user manual prior to first use.

This equipment must be placed on a stable, vibration-damped surface with adequate clearance for rotating components and electrical grounding. Operation without properly secured, balanced grinding jars and compatible grinding balls risks mechanical failure and projectile ejection.

  • Load Balance: Never operate the mill with an unbalanced load or with jars that are not securely locked into the holders.
  • Material Compatibility: Use grinding jar and ball materials that are chemically inert toward the sample to prevent contamination or exothermic reactions.
  • Overload Prevention: Do not exceed the recommended sample volume or grinding ball mass to avoid motor overheating and mechanical stress.
  • Electrical Safety: Disconnect the mill from the power supply before cleaning, maintenance, or any manual adjustment of moving parts.
  • Environment & PPE: Keep the operating area free of flammable materials and always wear safety glasses, a lab coat, and hearing protection during use.

This procedure guides the user through safe startup and operation of the mini planetary ball mill for material comminution. Follow each step sequentially to prevent mechanical hazards and ensure reproducible results.

Required Equipment: PBM-0.2 Ball Mill Main Unit, Semi-Circular Ball Milling Jars (ordered separately), Grinding Balls (ordered separately), Personal Protective Equipment (safety glasses, lab coat, hearing protection)

  1. Inspect Equipment
    Inspect the mill housing, power cord, and jar holders for any visible damage or looseness before proceeding.
  2. Prepare Grinding Jar
    Select the appropriate grinding jar and balls for your material, load the sample, and secure the jar lid tightly.
  3. Mount Jar
    Place the loaded jar into the designated holder on the planetary disk and lock it firmly into position.
  4. Set Speed and Guard
    Set the rotation speed using the control panel starting from a low value, then close the safety guard completely.
  5. Start Mill
    Start the mill and monitor for abnormal noise or excessive vibration; stop immediately if any irregularity occurs.
  6. Monitor Grinding Cycle
    Allow the mill to run for the required duration, checking periodically that the guard remains closed and the unit is stable.
  7. Stop and Unload
    Wait for the mill to come to a complete stop before opening the guard, then remove the jar and proceed with sample recovery.

How does the 1160 rpm maximum rotation speed of the PBM-0.2 impact its ability to produce nanomaterial-sized particles?

The PBM-0.2 achieves high-energy impact and friction through planetary motion at speeds up to 1160 rpm, enabling efficient grinding and nanomaterial preparation as stated in the product introduction. The 90W motor drives the main disk and four ball milling jars to perform composite revolution and rotation, which is specifically designed for small-batch, high-precision experimental requirements.

What are the dimensional constraints for grinding jars compatible with the PBM-0.2's jar holder?

The PBM-0.2 has a jar holder inner diameter of 50 mm and a revolution diameter of Φ111 mm, which limits the outer diameter of compatible grinding jars to no more than 50 mm. The unit is sold as a main machine only, so jars and grinding balls must be ordered separately to match these dimensions.

What laboratory infrastructure is required to accommodate the PBM-0.2's physical footprint and power needs?

The PBM-0.2 has overall dimensions of 420×260×310 mm and a net weight of 25 kg, making it suitable for a standard benchtop. It is powered by a 90W motor, and the listed price includes only the main unit; no special mounting or electrical modifications are specified, but a stable surface is recommended for safe high-speed operation.

The PBM-0.2 Mini Semi-Circular Planetary Ball Mill delivers high-speed planetary grinding (0–1160 rpm) for small-batch material preparation, optimized by its semi-circular jar design. However, the 90W motor and 50 mm jar holder limit throughput, and users must purchase jars and balls separately.

Positive

  • High-Efficiency Planetary Motion: Composite revolution and rotation of planetary wheels combined with high-energy impact and friction enable efficient grinding and mixing for nanomaterial preparation.
  • Optimized Semi-Circular Jar Design: The semi-circular ball milling jar design improves space utilization and grinding efficiency, making it suitable for small-batch, high-precision experimental requirements.

Trade-offs

  • Jars and Balls Not Included: The listed price covers only the main machine; grinding jars and balls must be ordered separately, adding initial setup cost and procurement lead time.
  • Limited Batch Capacity: With a 50 mm jar holder inner diameter and 90W motor, this micro-type mill is restricted to very small sample volumes, unsuitable for larger-scale processing.
