5L Vacuum Planetary Mixer for High Viscosity Battery Slurry

5L Vacuum Planetary Mixer for High Viscosity Battery Slurry

Product Overview

The TOB-XFZH05 5L Vacuum Planetary Mixer is a pilot-scale high-performance mixing system designed for battery slurry preparation and high-viscosity material processing.

It integrates planetary mixing, high-speed dispersion, vacuum degassing, and electric lifting structure, enabling stable and uniform mixing of complex electrode slurry systems. The vacuum environment effectively removes trapped air, improving slurry density, coating uniformity, and electrochemical consistency.

This equipment is widely used in laboratory research and pilot-scale process development, serving as a critical bridge between lab formulation and industrial battery slurry production.

Suitable viscosity range: ≤1.2 million cP

Key Features

• Pilot-Scale Vacuum Mixing System
Designed for battery slurry scale-up from laboratory to pilot production, ensuring process stability.

• High Viscosity Material Processing
Optimized for electrode paste and high solid content slurry systems up to 1.2 million cP.

• Vacuum Degassing Technology
Removes trapped air during mixing, improving electrode density and coating quality.

• Planetary + Dispersion Hybrid System
Combines low-speed kneading and high-speed shear for superior slurry uniformity and dispersion efficiency.

• Electric Lifting & Easy Operation
Enhances usability in pilot production environments and R&D laboratories.

Working Principle

The system operates through a multi-mechanism mixing process optimized for high-viscosity slurry systems:

• Planetary motion ensures full material circulation without dead zones
• High-speed disperser provides strong shear force for particle breakdown
• Vacuum system eliminates air bubbles during slurry formation
• Electric lifting structure improves process efficiency and safety
• Integrated scraping system ensures uniform mixing and clean discharge

This combined mechanism ensures high repeatability in battery electrode slurry formulation and pilot-scale material development.

Key Technical Advantages

• No Dead Zone Mixing System
The scraper system eliminates back-side dead zones and improves full material circulation. It reduces manual cleaning effort and enhances mixing uniformity. (Scraper is detachable for high-viscosity processes)

• Easy Cleaning Structure
The optimized gap design between planetary gearbox and vessel improves accessibility and cleaning efficiency, reducing residue accumulation.

• High Rigidity Structure
The mechanical rigidity is approximately 2× higher than conventional mixers, enabling stable operation under ultra-high viscosity conditions.

• Dynamic Temperature Monitoring
Temperature sensing is integrated through the low-speed shaft, improving measurement accuracy and extending sensor service life.

• Variable Cross-section Kneading Technology
Advanced spiral geometry enables continuous kneading of high-viscosity materials, improving mixing efficiency by 30%–40%.

• High-efficiency Dispersion System
Single dispersion disc achieves 137% efficiency compared to traditional dual-disc 5L systems, significantly reducing material splashing and improving dispersion quality.
