This document outlines the operational and safety constraints for the Atomfair SXQM-2 2L Dual Planetary Ball Mill. The equipment requires a stable, level surface and adherence to the specified electrical supply and operational time limits.
- Electrical Supply Requirement: The mill must be connected to a 220V-50Hz grounded power source with a dedicated circuit rated for the 0.75 kW motor load.
- Operational Time Limits: The maximum continuous running time per cycle is 9999 minutes with forward-reverse alternating intervals programmable from 1 to 999 minutes.
- Noise and Vibration Consideration: The unit generates up to 65 dB noise and significant vibration during operation, requiring placement on a vibration-dampening surface away from sensitive equipment.
- Weight and Stability: The 250 kg net weight demands a reinforced floor or bench and must never be operated on an uneven or mobile surface.
This procedure covers the safe initialization, operation, and shutdown of the SXQM-2 ball mill for laboratory grinding tasks. Proper handling minimizes risk of mechanical failure, injury, and material contamination.
Required Equipment: Grinding jar set (500 ml capacity, up to 4 jars), Grinding balls (appropriate size and material for sample), Jar sealing gaskets or vacuum accessories (if applicable)
- Inspect Equipment and Work Area
Inspect the mill, jars, and grinding balls for cracks, wear, or debris and verify the work surface is level and clear of flammable materials. - Load Material and Grinding Media
Load the sample material and grinding balls into the jar at a recommended ball-to-sample weight ratio of approximately 5:1, leaving adequate headspace for motion. - Secure Jars onto Planetary Disk
Place each filled jar onto the planetary disk and tighten the clamping mechanism evenly to prevent imbalance during rotation. - Set Operational Parameters
Set the desired revolution speed (70–560 rpm), total running time (1–9999 min), and forward-reverse alternating interval (1–999 min) using the variable frequency drive control panel. - Initiate Grinding Cycle
Press the start button and monitor the mill for 30 seconds, listening for abnormal noise or excessive vibration and stopping immediately if observed. - Monitor and Intervene if Necessary
Periodically check the mill during operation and use the pause function to inspect jars if the process requires sample removal or parameter adjustment. - Stop and Unload After Cycle Completion
After the programmed cycle ends, allow the mill to come to a complete stop before unfastening and removing the jars for cleaning or sample collection.
How does the increased centrifugal force in the SXQM-2 double planetary ball mill affect contamination from jar and ball wear, and what material options minimize this risk?
The high-energy milling environment of the SXQM-2 can accelerate wear on grinding jars and balls, potentially introducing impurities into the sample. To minimize contamination, the mill supports a wide range of jar and ball materials—including agate, zirconia ceramic, alumina corundum ceramic, stainless steel, tungsten carbide, and silicon nitride—allowing researchers to select chemically compatible, low-wear combinations for their specific materials.
Can the SXQM-2 mill air-sensitive or pyrophoric materials under vacuum or inert atmosphere?
Yes, the SXQM-2 model offers optional vacuum grinding jars in sizes 50–250 ml, which can be sealed to maintain an inert atmosphere or vacuum during milling. This enables safe processing of air-sensitive and moisture-sensitive powders without requiring direct integration into a glovebox, although the mill's 250 kg weight and 1150×800×760 mm footprint preclude placement inside most gloveboxes.
What are the electrical power and physical space requirements for installing the SXQM-2 ball mill in a typical laboratory?
The SXQM-2 requires a standard 220V, 50Hz power supply and a 0.75 kW motor with variable frequency drive. The unit weighs 250 kg, has overall dimensions of 1150×800×760 mm, and operates at a noise level of 60±5 dB, so it needs a robust, level floor with adequate clearance for ventilation and access, but no specialized soundproofing is necessary for typical lab environments.
The SXQM-2 dual planetary ball mill delivers enhanced grinding efficiency through multiplied centrifugal forces from its dual planetary action, enabling nanoscale particle size reduction for advanced materials processing. Its 0.75 kW variable-frequency motor and robust welded steel construction support high-energy milling at noise levels up to 65 dB, with a total weight of 250 kg requiring adequate bench or floor support.
Positive
- Enhanced grinding efficiency to nanoscale: The dual planetary design multiplies centrifugal force on grinding balls, significantly increasing collision, shearing, and friction. This enables grinding of some materials down to nanometer scale.
- Robust construction with low-noise operation: The shell is welded with thickened steel plate for high strength and deformation resistance. Precision gears and CNC-processed parts ensure stable, safe, and low-noise operation at high speed.
Trade-offs
- 220V-50Hz power supply requirement: The mill is designed exclusively for 220 V AC at 50 Hz. Laboratories with different mains voltage or frequency must use a suitable transformer or frequency converter, adding infrastructure cost.
- Heavy benchtop unit at 250 kg: With a net weight of 250 kg and dimensions of 1150×800×760 mm, the mill requires a reinforced workbench or floor capable of supporting concentrated loads. Relocation after installation is challenging.
