Applications
- Paint and pigment dispersion
- Inkjet ink and digital printing ink milling
- Battery cathode/anode slurry grinding (LFP, NCM, graphite)
- Pharmaceutical wet milling and nanosuspension
- Ceramic glaze and electronic paste processing
Key Features
- Ultra-low wear rate minimizes product contamination
- High density provides superior kinetic energy transfer
- Excellent sphericity for uniform bead packing and flow
- Wide size range from 0.1 mm (nano-milling) to 3.0 mm (coarse grinding)
- Chemical inertness — resistant to acids, alkalis, and solvents
