The DPBM-4 requires a 220V-50Hz power supply and generates noise up to 65 dB. Users must select compatible grinding jars and balls separately and adjust speed and time to avoid over-grinding from the higher energy output.
- Power Supply: Operate the DPBM-4 only with a 220V-50Hz power supply and ensure proper grounding.
- Noise Emission: The mill operates at 60±5 dB, requiring hearing protection during extended operation.
- Jar and Media Compatibility: Only use compatible 1000ml grinding jars and balls ordered separately to avoid mechanical failure.
- Over-Grinding Prevention: Adjust speed and grinding time to avoid over-grinding, as the dual planetary structure delivers higher energy than standard mills.
- Installation Support: Professional installation guidance and operational training are available upon request.
The DPBM-4 is a high-energy ball mill requiring careful parameter selection and jar preparation. Follow these steps to ensure safe and effective grinding.
Required Equipment: DPBM-4 Dual Planetary Ball Mill
- Verify Power Supply
Confirm the electrical outlet provides 220V-50Hz and the mill is properly grounded. - Select and Prepare Jars
Select compatible grinding jars and balls based on target material and load material and media into jars, ensuring jars are sealed properly. - Set Grinding Parameters
Set the total running time and forward-reverse alternating time using the variable frequency control according to your grinding protocol. - Start and Monitor
Start the mill and monitor operation, adjusting speed if necessary to avoid over-grinding due to the higher energy output. - Complete and Unload
Allow the mill to complete its cycle and stop completely before opening the jars to unload the ground material.
How does the dual planetary structure of the DPBM-4 enhance grinding energy compared to conventional planetary ball mills?
The DPBM-4's dual planetary design uses a larger revolution radius and higher rotation speed than ordinary planetary mills of the same specification, multiplying centrifugal force on the grinding balls. This significantly increases collision, shearing, and friction, enabling some materials to be ground to nanometer scale. The revolution speed range is 70–560 r/min and rotation speed 140–1120 r/min.
What jar materials are available for the DPBM-4 to prevent cross-contamination in sensitive applications?
The DPBM-4 is compatible with 1000 ml grinding jars in materials including WC-Co, Al₂O₃, Agate, YSZ, SS, PU, Ceramic, and Nylon. Vacuum grinding jars from 50–1000 ml are also available. Users must select jar and ball materials compatible with their target material to avoid cross-contamination.
What programmable operating parameters does the DPBM-4 support for customized milling protocols?
The DPBM-4 features variable frequency speed control with a total set running time range of 1–9999 minutes and forward-reverse alternating time range of 1–999 minutes. This allows users to program customized grinding cycles for different material requirements.
The DPBM-4 Dual Planetary Ball Mill employs a double planetary drive with larger revolution radius and rotation speed than standard planetary mills, multiplying centrifugal force for nanometer-scale grinding capability. Variable frequency control (70–560 rpm revolution, 140–1120 rpm rotation) with programmable forward-reverse cycles (1–999 min) and total run time (1–9999 min) enables flexible high-energy milling protocols. Jar and media must be sourced separately, and the higher energy density requires careful parameter adjustment to avoid over-grinding.
Positive
- Nanometer-scale grinding capability: The dual planetary structure multiplies centrifugal force, enhancing collision, shearing, and friction to achieve nanometer-scale particle sizes for advanced materials.
- Programmable variable frequency control: Variable frequency speed control with total set running time (1–9999 min) and forward-reverse alternating time (1–999 min) allows customized grinding protocols for different material requirements.
Trade-offs
- Jars and media ordered separately: The main unit does not include grinding jars or balls; these must be sourced separately, adding to initial procurement complexity and cost.
- Higher energy requires careful adjustment: The dual planetary design delivers significantly higher energy than standard mills, requiring users to adjust speed and grinding time to avoid over-grinding or material degradation.
