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 designed for high-viscosity material mixing and battery slurry preparation in laboratory and pilot-scale applications. It integrates planetary mixing, high-speed dispersion, vacuum degassing, and lifting bucket structure, enabling efficient production of uniform and bubble-free slurry systems.

It is widely used in lithium-ion batteries, solid-state batteries, sodium-ion batteries, and advanced material research, especially for electrode slurry with high solid content and high viscosity.

This equipment is specifically optimized for battery electrode paste mixing, ensuring improved dispersion uniformity, reduced air entrapment, and higher slurry density.

Suitable viscosity range: ≤1.2 million cP

Application

This 5L vacuum planetary mixer is suitable for:

• Lithium-ion battery cathode and anode slurry mixing
• Solid-state battery material research
• Sodium-ion battery electrode slurry preparation
• High-viscosity ceramic and functional material mixing
• Conductive paste and polymer dispersion
• Laboratory 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.
