Store the mill in a dry, dust-free environment below 40°C to prevent motor and bearing degradation. Operate only with all protective covers in place and ensure the grinding chamber is sealed before starting to contain airborne particulates.
- Electrical Safety: The 220 V AC motor requires a grounded outlet and a dedicated circuit breaker to prevent overload and electrical shock.
- Mechanical Lockout: Never open the lid or touch rotating parts while the turntable is in motion; wait for complete stop after shutting off power.
- Jar Integrity: Inspect agate jars for cracks or chips before each use and adjust the sealing pressure gradually to avoid over-tightening and fracture.
- Vacuum Operation: For vacuum grinding, verify the jar seal O-ring is undamaged and the vacuum line is connected before initiating the cycle.
- Dust Containment: Use only with the provided lid gasket and collect any spillage immediately using a HEPA-filtered vacuum to minimize airborne contamination.
This procedure covers safe initialization and shutdown of the mill for dry, wet, or vacuum grinding. Always follow lockout/tagout steps before maintenance or cleaning.
Required Equipment: 4 x Agate grinding jars with sealing caps, Vacuum pump (if performing vacuum grinding), Sealing pressure adjustment tool (graduated scale)
- Inspect mill and jars
Inspect the mill chamber, jars, and seals for cracks, debris, or wear before loading samples. - Load jars and seal
Distribute sample and grinding media evenly into the jars, then tighten the sealing cap using the graduated scale to the recommended pressure. - Place jars into holders
Insert each sealed jar into its holder on the planetary turntable and secure the locking mechanism. - Set rotation parameters
Set the revolution speed between 35 and 335 r/min and the jar rotation speed up to 1160 r/min using the control panel. - Start grinding cycle
Close the lid, engage the safety lock, and press the start button to begin the programmed grinding cycle. - Monitor and stop
Allow the cycle to complete automatically or press the emergency stop if any abnormal noise, vibration, or odor is detected. - Unload jars and clean
Wait for the mill to come to a complete stop, then unlock and remove jars, and clean all contacted surfaces with a dry cloth.
What is the advantage of using agate grinding jars over other materials when performing soil heavy metal analysis with the XQM-0.2 mini planetary ball mill?
Agate jars minimize contamination because they are chemically inert and non-metallic, ensuring no metal ions are introduced into the sample during grinding. The standard configuration includes 4 x 250 ml agate jars with 700 agate balls, specifically designed for heavy metal analysis in soil. This setup supports dry, wet, and vacuum grinding modes to maintain sample integrity.
Can the XQM-0.2 grind materials other than soil, and what are the feed size limitations?
Yes, the mill can grind materials other than soil, but the feed particle size must be ≤3 mm for non-soil samples, while soil samples can be fed at ≤10 mm. The discharge particle size can be as fine as 0.1 μm, enabling versatile use across various sample types. This constraint ensures efficient grinding and protects the agate jars from excessive wear.
What are the power and continuous operation capabilities of the XQM-0.2 mini planetary ball mill?
The XQM-0.2 operates on 220V AC with a 90W motor, and its three-phase variable frequency controller allows stepless speed regulation. It can run continuously for up to 48 hours at full load, with automatic forward-reverse cycling and timing for unattended operation. The overall dimensions are 420×260×310 mm and net weight is 25 kg, making it suitable for benchtop installation.
The Atomfair XQM-0.2 Mini Planetary Ball Mill is optimized for soil heavy metal analysis, achieving sub-micron particle sizes (down to 0.1 μm) via high-speed planetary action, but imposes feed size limits of ≤10 mm for soil and ≤3 mm for other materials, and the agate jar construction requires careful handling to prevent brittle fracture.
Positive
- Ultra-fine grinding capability: Discharge particle size as fine as 0.1 μm enables thorough sample homogenization for sensitive heavy metal analysis in soil.
- Multi-mode grinding flexibility: Supports dry, wet, and vacuum grinding modes, allowing adaptation to various sample types and analytical protocols without additional equipment.
Trade-offs
- Brittle agate jar material: Agate grinding jars are inherently brittle and prone to chipping or cracking under impact from hard or oversized feed particles, necessitating careful feed preparation and handling.
- Feed size restrictions for non-soil samples: Feed particle size is limited to ≤3 mm for materials other than soil, requiring pre-crushing or sieving for most geological or synthetic samples before milling.
