850L Vacuum Double Planetary Mixer | Lithium Battery Slurry Equipment
The 850L Vacuum Double Planetary Mixer is a large-scale industrial mixing system designed for high-viscosity lithium battery slurry production.
Based on industrial design principles widely used in advanced mixing equipment such as Maxwell vacuum planetary mixers, this system integrates:
Planetary stirring
High-speed dispersion
Vacuum deaeration
High-torque kneading
It is widely used in the production of lithium-ion battery electrode slurries, including LFP, NCM, graphite anode, silicon-carbon composites, and energy storage materials.
The system ensures uniform dispersion, stable viscosity control, and bubble-free slurry output, which is critical for high-performance battery manufacturing.
Working Principle
The mixer works through a dual planetary motion system combined with high-speed dispersion technology, similar to industrial vacuum mixers used in Maxwell mixing systems.
1. Planetary Mixing Motion
Two agitators rotate around their own axis while simultaneously revolving around the tank center.
This ensures:
Full material circulation
No dead zones
High uniformity in slurry structure
2. High-Speed Dispersion System
A high-speed disperser operates up to 2980 rpm, generating strong shear force to break particle agglomeration.
Improves:
Conductive carbon dispersion
Active material distribution
Slurry fineness
3. Vacuum Deaeration System
Under vacuum conditions (-0.09 MPa), trapped air and microbubbles are removed.
Benefits:
Higher electrode density
Better coating consistency
Improved battery cycle performance
