The DPBM-6 ball mill requires a 220V-50Hz power supply with proper grounding. Reduce feed quantity or adjust speed if the overload protection system trips during operation.
- Material Compatibility: Select grinding jar and ball materials compatible with the target material to avoid cross-contamination.
- Over-Grinding Prevention: Adjust speed and grinding time to avoid over-grinding due to the mill's higher energy output compared to standard planetary mills.
- Jar Capacity Limit: Use only grinding jars up to 1500 ml capacity, with vacuum jars available from 50 to 1000 ml.
- Load Management: Fill grinding balls to no more than 40% of the jar capacity to prevent excessive load on the motor.
The DPBM-6 mill is a high-energy grinding instrument requiring careful setup and parameter selection. Follow these steps to safely initialize a milling run.
Required Equipment: DPBM-6 Main Unit, Grinding Jars, Grinding Balls
- Select compatible grinding jars and balls
Select grinding jars and balls made of materials compatible with the target sample to avoid cross-contamination. - Load the jars with balls and material
Load the grinding jars with grinding balls up to 40% of jar capacity and add the material to be ground. - Set the total running time
Set the total running time between 1 and 9999 minutes using the variable frequency controller. - Set the forward-reverse alternating time
Set the forward-reverse alternating time between 1 and 999 minutes for the milling cycle. - Adjust the revolution speed
Adjust the revolution speed to between 70 and 560 r/min for optimal grinding energy. - Adjust the rotation speed
Adjust the rotation speed to between 140 and 1120 r/min for the desired grinding action. - Start the milling cycle
Initiate the milling cycle by activating the variable frequency drive and monitor for overload protection activation.
How does the double planetary design of the DPBM-6 improve grinding energy compared to standard planetary ball mills?
The DPBM-6's double planetary structure uses a larger revolution radius and higher rotation speeds (revolution 70–560 r/min, rotation 140–1120 r/min) than ordinary planetary mills, multiplying centrifugal force on the grinding balls. This significantly enhances collision, shearing, and friction, enabling nanometer-scale particle sizes for advanced materials. The precision gear drive maintains stable operation at 60±5 dB noise level.
Which jar and ball materials are compatible with the DPBM-6 for contamination-sensitive grinding applications?
The DPBM-6 accepts 1500 ml grinding jars (50–1000 ml vacuum jars available) in materials including WC-Co, Al₂O₃, Agate, YSZ, SS, PU, Ceramic, and Nylon. Grinding balls are available in WC-Co, Al₂O₃, Agate, YSZ, SS, and IC-PU. All jars and balls are ordered separately; material selection must match the target sample to avoid cross-contamination.
What are the power and overload protection specifications for the DPBM-6?
The DPBM-6 operates on 220V-50Hz with a 0.75 kW variable-frequency motor. It includes built-in overload protection that automatically shuts down the motor under excessive load to prevent equipment damage. Programmable settings allow total running time from 1 to 9999 minutes and forward-reverse alternating time from 1 to 999 minutes.
The Atomfair DPBM-6 6L double planetary ball mill offers high-energy grinding with nanometer-scale capability and overload protection, but requires separate purchase of jars and media and careful load management to avoid protection system activation.
Positive
- High-Energy Dual Planetary Grinding: The double planetary structure multiplies centrifugal force, enabling nanometer-scale particle size reduction through enhanced collision, shearing, and friction, outperforming standard planetary mills.
- Overload Protection for Safety: Built-in overload protection automatically shuts down the motor under excessive load, preventing equipment damage and ensuring operator safety during high-energy milling.
Trade-offs
- Jars and Media Ordered Separately: Grinding jars and balls are not included with the main unit; users must select compatible materials (e.g., WC-Co, Al₂O₃, YSZ) to avoid cross-contamination, adding procurement complexity and cost.
- Potential Overload Tripping: The overload protection system may activate during high-load conditions; operators must reduce feed quantity or adjust speed to prevent tripping, requiring careful process optimization.
