Ruijing Unveils Next-Gen 2000L Gigafactory Lithium Battery Slurry Mixing Station
As global energy storage and electric vehicle gigafactories transition toward high-nickel ternary cathodes (NMC 811 / 9.5.5) and silicon-carbon anodes, traditional planetary mixers face severe bottlenecks: metallic contamination, air entrapment micro-voids, and severe viscosity stratification.
1. Deep Vacuum Deaeration Down to -0.098 MPa
Ruijing Automation’s newly patented mechanical seal enclosure eliminates microscopic air entrapment during high-speed dispersion. Operating at vacuum levels ≤ -0.098 MPa (0.5 mbar absolute), the RJ-VPM-2000L achieves a 99.98% degassing efficiency, drastically lowering internal resistance (DCR) and boosting cycle life in lithium-ion battery cells.
2. 5-Axis CNC Machined Helical Twist Blades
The dual planetary blades are precision milled on 5-Axis CNC centers with a strict 1.5mm to 3.0mm clearance against the inner vessel wall. This tight mechanical envelope generates immense macro-convective folding and high shear rates, homogenizing ultra-high solids content (up to 78% solid loading) within 90 minutes.
Key Innovation Summary:
- Zero metallic contamination via tungsten carbide and ceramic lining options.
- Dual independent high-shear dispersion shafts variable from 0 to 4,500 RPM.
- Continuous closed-loop powder vacuum transfer with gravimetric feeder synchronization.
- Integrated SCADA / Siemens S7-1500 PLC recipe automation.
3. Factory Acceptance Testing (FAT) & Global Delivery
Every production cell leaves Ruijing’s Dongguan manufacturing hub only after passing 100% FAT verification, helium vacuum mass spectrometry leak checks, and 72-hour continuous temperature stability validation under simulated high-viscosity loads.
