The PBM-6 planetary ball mill requires sealed grinding jars with adjustable pressure to contain samples during high-speed rotation. Jar and ball materials must be selected to match the target material to avoid cross-contamination.
- Sealing Pressure Adjustment: The sealing pressure of the grinding jars is adjustable via a graduated scale to prevent sample leakage during high-energy operation.
- Material Compatibility: Jar and ball materials must be selected to avoid cross-contamination with the target sample material.
- Grinding Jar Procurement: Grinding jars and balls are ordered separately from the main unit and must be procured before operation.
This procedure describes the safe operation of the PBM-6 planetary ball mill for soil sample preparation. The grinding process requires proper selection of jars and balls, adjustment of sealing pressure, and use of the electric screener for particle size analysis.
Required Equipment: PBM-6 Planetary Ball Mill, Electric Screener, Grinding Jars, Grinding Balls
- Select and Prepare Grinding Jars
Select grinding jars and balls made of materials compatible with the soil sample to avoid cross-contamination, and fill the jars with grinding balls to 40% of their capacity. - Load Sample Material
Load the soil sample with feed size ≤10 mm into the grinding jars, ensuring the jar capacity is not exceeded. - Seal Jars and Adjust Pressure
Seal the grinding jars and adjust the sealing pressure using the graduated scale to prevent leakage during operation. - Set Grinding Parameters
Set the desired rotation speed (0–670 r/min), operation time, and forward-reverse commutation on the variable frequency controller. - Start Grinding Operation
Start the grinding process and allow the machine to run for the programmed duration, supporting up to 48 hours of continuous operation. - Stop and Unload Jars
Stop the mill after grinding, carefully unload the jars, and retrieve the ground sample. - Screen Ground Sample
Use the included electric screener with seven-layer sieves (20–200 mesh) to classify the ground sample for particle size analysis.
What is the maximum achievable particle size reduction for soil heavy metal analysis using the PBM-6, and what feed size does it accept?
The PBM-6 can achieve output particle sizes as fine as 0.1 μm from soil feed ≤10 mm. This is enabled by the planetary high-energy impact with jar rotation speed up to 670 r/min and revolution diameter Φ234 mm.
Which grinding jar materials are recommended for soil heavy metal analysis to avoid cross-contamination?
For soil heavy metal analysis, agate (natural SiO₂) or YSZ (yttria-stabilized zirconia) jars are recommended to minimize metal contamination. The PBM-6 accepts 1500 ml jars in materials including Al₂O₃, Agate, YSZ, WC-Co, SS, PU, Ceramic, and Nylon, but agate and YSZ are preferred for zero-metal or low-metal analysis.
What are the requirements for continuous 48-hour operation of the PBM-6 at full load?
The PBM-6 is designed for 48-hour continuous operation at full load with its industrial-grade 0.75KW motor and variable frequency controller. It supports automatic forward-reverse commutation and timing. The system includes an electric screener with seven-layer sieves for integrated grinding and screening. Ensure proper ventilation and stable power supply.
The PBM-6 planetary ball mill provides ultrafine grinding down to 0.1 μm for soil heavy metal analysis, with 48-hour continuous operation and an integrated electric screener with sieves from 20-200 mesh, but requires separate purchase of grinding jars and media.
Positive
- 48-Hour Continuous Operation: Industrial-grade 0.75KW motor with variable frequency controller enables 48-hour uninterrupted grinding at full load, with automatic forward-reverse commutation and timing for maximum throughput.
- Ultrafine Output Down to 0.1 μm: From soil feed up to 10 mm, the planetary high-energy impact with adjustable sealing pressure yields consistent sub-micron particle refinement for heavy metal analysis.
Trade-offs
- Grinding Jars and Media Not Included: The main unit ships without grinding jars and balls; four 1500 ml jars and 40% jar capacity of grinding media must be ordered separately, increasing total cost and procurement lead time.
- Heavy Unit Requires Robust Lab Bench: Weighing 100 kg with dimensions 760×470×580 mm, the PBM-6 requires a sturdy, vibration-dampened surface and adequate floor space for safe operation.
