Planetary Ball Mill PBM-16A 16L 3KW Soil Grinder ATOMFAIR®

The PBM-16A is a powered mechanical mill with rotating masses and electrical hazard potential requiring controlled installation and operation. Grinding jars and balls must be ordered separately and selected for material compatibility to avoid cross-contamination.

• Electrical and Mechanical Safety: The 3KW motor and variable frequency controller require a stable 220V AC supply and must be operated within the specified 48-hour continuous full-load limit to prevent overheating.
• Jar and Media Compatibility: Grinding jar sealing pressure must be adjusted via the graduated scale to prevent leakage or jar failure during high-energy planetary operation.
• Material Cross-Contamination Risk: Select jar and ball materials (e.g., WC-Co, Al₂O₃, Agate, YSZ, SS, PU, Ceramic, Nylon) that are chemically inert to the sample to avoid introducing contaminants into soil heavy metal analysis.
• Feed Particle Size Constraint: Feed particle size must not exceed 10 mm for soil samples or 3 mm for other materials to prevent jamming or damage to the grinding mechanism.

This procedure covers initial setup, jar loading, and operation of the PBM-16A for ultrafine soil grinding. Always consult the user manual for detailed maintenance and troubleshooting before first use.

Required Equipment: PBM-16A main grinding unit, Grinding jars (4 L, ordered separately), Grinding balls (40% jar capacity, ordered separately), Electric screener with sieve set (included)

1. Inspect and Prepare Jars
   Inspect each grinding jar for cracks or damage, then fill to approximately 40% capacity with grinding balls and add the soil sample, leaving adequate headspace for grinding action.
2. Seal Jars with Graduated Scale
   Seal each jar using the graduated scale to apply consistent, adjustable sealing pressure, ensuring no leakage during high-speed planetary rotation.
3. Load Jars into Mill
   Load two or four jars symmetrically into the jar holders on the turntable, securing them firmly to prevent imbalance during operation.
4. Set Grinding Parameters
   Set the revolution speed (35–335 r/min), rotation speed (70–670 r/min), and forward-reverse commutation cycle using the variable frequency controller with power display.
5. Start Grinding Cycle
   Start the grinding cycle and monitor the power display and timer, allowing continuous operation up to 48 hours at full load for maximum throughput.
6. Stop and Unload Jars
   Stop the mill after the programmed cycle completes, allow the jars to cool if necessary, then carefully unload and open them to retrieve the ground sample.
7. Screen Ground Sample
   Transfer the ground sample to the electric screener fitted with the appropriate mesh sieves (20–200 mesh) and run at 1400 rpm vibration frequency to achieve the desired particle size fraction.

The PBM-16A semi-circular planetary ball mill integrates a 3 kW drive with a 16 L capacity and an electric screener for soil heavy metal analysis, delivering ultrafine grinding down to 0.1 μm from ≤10 mm feed. Its 48-hour continuous operation and adjustable jar sealing pressure support dry, wet, and vacuum modes, but the 205 kg weight and separate jar/ball procurement are practical deployment constraints.

Positive

• Ultrafine output down to 0.1 μm: Achieves sub-micron particle refinement from soil feed ≤10 mm, critical for heavy metal analysis requiring high surface area and homogeneity.
• 48-hour continuous full-load operation: Industrial-grade 3 kW motor with variable frequency controller and automatic forward-reverse commutation enables uninterrupted long-duration grinding for high-throughput sample processing.

Trade-offs

• Heavy unit at 205 kg net weight: The 205 kg mass requires robust benchtop or floor support and may complicate relocation or installation in space-constrained labs.
• Grinding jars and balls ordered separately: Jars and balls are not included in the standard configuration, requiring additional procurement and material compatibility selection to avoid cross-contamination.
