The DPBM-2 is a high-energy mechanical mill with electrical and mechanical hazards. Proper jar and ball material selection is required to avoid cross-contamination and over-grinding.
- Electrical Supply: Operate the mill only with a 220V-50Hz grounded power supply and a 0.75 kW motor circuit.
- Mechanical Stability: Place the mill on a stable, level surface that can support its 250 kg weight to prevent tipping.
- Jar and Ball Selection: Select grinding jars and balls that are chemically compatible with the target material to avoid cross-contamination.
- Over-grinding Prevention: Adjust the revolution speed and grinding time according to the material to avoid over-grinding due to the mill's high energy output.
- User Manual: Consult the user manual for comprehensive installation, operation, and maintenance instructions prior to first use.
The DPBM-2 requires proper setup and material selection for safe operation. Follow these steps to prepare and run the mill for grinding.
Required Equipment: Grinding jars (500 ml), Grinding balls (set, 40% of jar capacity)
- Inspect Power Supply
Inspect the power supply voltage and ensure the mill is connected to a 220V-50Hz grounded outlet. - Select Compatible Jars and Balls
Select grinding jars and balls that are chemically compatible with the target material to avoid cross-contamination. - Load Jars with Material and Balls
Load the grinding jars with the sample material and grinding balls up to 40% of the jar capacity. - Set Running Parameters
Set the total running time and forward-reverse alternating time using the variable frequency control panel. - Start and Adjust Speed
Start the mill and adjust the revolution speed between 70-560 rpm as needed to avoid over-grinding. - Consult Manual for Post-Operation
Consult the user manual for detailed instructions on jar removal and maintenance after each run.
What is the maximum achievable particle size reduction with the DPBM-2 dual planetary ball mill, and how does the dual planetary structure enable nanometer-scale grinding compared to conventional planetary mills?
The DPBM-2 can achieve nanometer-scale particle sizes due to its dual planetary structure, which provides a larger revolution radius and rotation speed than ordinary planetary mills, multiplying centrifugal force. The revolution speed range is 70–560 r/min and rotation speed 140–1120 r/min, delivering significantly higher collision, shearing, and friction energy for ultrafine grinding.
Which grinding jar materials are compatible with the DPBM-2 for contamination-sensitive applications, and can vacuum grinding be performed?
The DPBM-2 is compatible with 500 ml grinding jars in materials including WC-Co, Al₂O₃, Agate, YSZ, SS, PU, Ceramic, and Nylon, allowing selection to avoid cross-contamination. Vacuum grinding is supported using 50–250 ml vacuum grinding jars, which are available separately for oxygen- or moisture-sensitive materials.
What are the power supply and noise level requirements for operating the DPBM-2 in a standard laboratory?
The DPBM-2 operates on a 220V-50Hz power supply with a 0.75 kW motor and produces a noise level of 60±5 dB, making it suitable for typical lab environments. The unit weighs 250 kg and has overall dimensions of 1150×800×760 mm, requiring adequate floor space and ventilation.
The Atomfair DPBM-2 Dual Planetary Ball Mill (2L variable frequency) employs a double planetary structure that multiplies centrifugal force, enabling nanoscale grinding for advanced materials. Its heavy-duty construction and precision gear drive deliver stable, low-noise operation (60±5 dB). Grinding jars and media are ordered separately, and its higher energy output demands careful speed and time adjustment to prevent over-grinding.
Positive
- Dual planetary high-energy grinding: The double planetary structure provides a larger revolution radius and speed than ordinary mills, multiplying centrifugal force for enhanced collision, shearing, and friction, capable of achieving nanometer-scale particle sizes.
- Heavy-duty low-noise construction: Thickened steel plate welding and precision gear drive ensure stable, impact-resistant operation with noise levels of 60±5 dB, suitable for continuous lab use.
Trade-offs
- Jars and media purchased separately: Grinding jars and balls must be ordered separately, requiring careful selection of compatible materials (e.g., WC-Co, Al₂O₃, YSZ, agate) to avoid cross-contamination with the sample.
- Higher energy requires protocol adjustment: The dual planetary design delivers significantly higher impact energy than standard mills; users must adjust speed and grinding time downward to avoid over-grinding or excessive wear.
