Dual Planetary Ball Mill DPBM-0.4 0.4L 560rpm ATOMFAIR®

The DPBM-0.4 must be installed on a level, stable surface capable of supporting 250 kg to prevent vibration-induced misalignment. Operating environment must be dry, well-ventilated, and free of flammable or corrosive atmospheres to ensure electrical safety and motor longevity.

• Electrical safety: 220V-50Hz supply with proper grounding and overload protection required.
• Noise exposure: 58±5 dB at 1m; hearing protection recommended during extended operation.
• Over-grinding risk: Dual planetary design multiplies centrifugal force; monitor particle size to prevent excessive comminution.
• Cross-contamination: Select jar and ball materials chemically compatible with target sample to avoid contamination.
• Heavy equipment handling: 250 kg weight; use appropriate lifting aids during installation and relocation.

The DPBM-0.4 requires careful setup to ensure safe and effective high-energy grinding. Following these steps will help achieve nanometer-scale particle sizes while avoiding equipment damage or sample contamination.

Required Equipment: Four compatible grinding jars (50-100 ml capacity), Grinding balls (material specific, fill to 40% jar volume), User manual for detailed operation and maintenance instructions

1. Inspect and prepare work area
   Inspect the main unit for shipping damage and place it on a level, stable surface rated for 250 kg.
2. Install grinding jars and balls
   Select four grinding jars compatible with your material, fill each to 40% capacity with grinding balls, and securely attach jars to the mill.
3. Set operating parameters
   Set total running time (1-9999 min), forward-reverse alternating time (1-999 min), revolution speed (70-560 rpm), and rotation speed (140-1120 rpm) using the variable frequency control panel.
4. Verify safety and start mill
   Confirm the safety lid is closed and jars are properly fastened, then start the mill and monitor for unusual noise or vibration.
5. Monitor and adjust grinding process
   Monitor particle size progression and adjust speed or time as needed to prevent over-grinding, especially when processing nanocomposites.

The Atomfair DPBM-0.4 Dual Planetary Ball Mill is a 0.4L laboratory-grade high-energy grinder with a double planetary structure that multiplies centrifugal force for nanometer-scale grinding, but requires separate purchase of jars and balls and careful speed adjustment to avoid over-grinding.

Positive

• High-energy dual planetary design: The double planetary structure with larger revolution radius and rotation speed multiplies centrifugal force, enhancing collision, shearing, and friction for efficient nanometer-scale particle size reduction.
• Versatile jar and mode compatibility: Supports 50–100ml grinding jars in multiple materials (WC-Co, Al₂O₃, Agate, YSZ, SS, PU, Ceramic, Nylon) and dry, wet, or vacuum grinding modes, enabling broad material processing flexibility.

Trade-offs

• Jars and balls ordered separately: Grinding jars and balls are not included with the main unit, requiring additional procurement and material compatibility selection to avoid cross-contamination.
• Risk of over-grinding at high energy: The dual planetary structure delivers significantly higher energy than standard mills, necessitating careful adjustment of speed and grinding time to prevent over-grinding or material degradation.
